Virginal

1. Nomenclature and construction.

The precise application of the term ‘virginal’ is much debated, partly because of its use in England to denote all quilled keyboard instruments well into the 17th century. Although some writers still reserve the term for rectangular instruments, present usage generally applies it to instruments whose strings run at right angles to the keys, rather than parallel with them as in a harpsichord or at an oblique angle as in a Spinet. A distinction based on the supposed uniqueness of a virginal’s having two bridges resting on free soundboard is no longer tenable, since this is also the case with some harpsichords where the wrest plank is hollowed out under the nut (wrest-plank bridge), and some virginals have one bridge deadened by a massive plank underneath the soundboard. However, ‘spinet’ is often applied to polygonal Italian virginals (in English and in German) because of the similarity to the Italian word ‘spinetta’. The late 16th-century Italian name for the rectangular virginal was spinetta, while the most common word for polygonal instruments was Arpicordo. During the 17th century, however, ‘spinetta’ came to be accepted in Italy as a generic term for any plucked keyboard instrument smaller than a harpsichord. The term ‘clavicordio’ was used in the 16th century to mean any kind of plucked keyboard instrument, but also specifically for the polygonal virginal. The word virginale did not appear in this sense in Italian usage until the 20th-century revival of early music. (For further discussion of terminology, see Spinet; for Flemish usage, see §3 below.)

The derivation of the term ‘virginal’ remains in dispute, the association with the Latin virga (‘rod’) being unproved and that with Elizabeth I (‘the virgin queen’) being without foundation. The term probably derives in some way, however, from the instrument’s association with female performers – Marcuse suggested that this results from a confusion between ‘timbrel’ (a frame drum played by women since biblical times) and the ‘cymbel’ in such terms as ‘cembalo’, ‘clavicymbel’ etc. – or from its tone, which some theorists likened to a young girl’s voice (vox virginalis). The term ‘pair of virginals’, to be found in early literature derived from organ terminology, denotes a single instrument.

In contrast to those of a spinet, the long bass strings of a virginal are at the front, making it possible to build the instrument in a wide variety of shapes, from squat rectangles to more or less graceful polygons, depending on whether the keyboard is inset or projecting. The rectangular form would appear to have been the earliest. It is cited in the manuscript treatise of Paulus Paulirinus of Prague (c1460), who described the virginal as ‘an instrument having the shape of a clavichord and metal strings making the sound of a harpsichord’. This form was also the one known to Virdung, who showed a small rectangular instrument with a projecting keyboard having a range of just over three octaves (FGg'', lacking F) in his Musica getutscht (1511). Non-rectangular instruments appear in early 16th-century Italian representations, notably intarsias in the Vatican and Genoa Cathedral, as well as Giorgione’s well-known Concert in the Pitti Palace, Florence, all dating shortly after 1510. An earlier example is the intarsia from about 1506 in Isabella d’Este’s grotta in the Palazzo Ducale, Mantua, which probably represents an instrument made for her in 1496 by Lorenzo da Pavia, and is the earliest example of a C/E–c'''compass in a virginal (see Wraight, ii, pp.198–201). Like the intarsia in the Vatican, this instrument has some curved case sides and suggests that virginals may have been made in a variety of shapes before the straight-sided, pentagonal design became established.

The bridges of Italian virginals were invariably parallel-sided with a moulding on the top edge, but North European instruments usually have a triangular section. The right hand bridge of any virginal usually has a pronounced curve in the treble; this was always bent in Italian virginals but may be sawn in other traditions. All instruments at quart, quint and octave pitch sometimes have the right bridge (at least partly) made of straight sections. In the North European traditions the left hand bridge is virtually straight, but most Italian virginals have a curve at the bass end.

In a typical virginal the jacks are placed along a line running from the front of the instrument at the left to the back of the instrument at the right. The key-levers are correspondingly quite short in the bass and quite long in the treble, giving the keyboard of the virginal a characteristic touch, and, in some cases, making it difficult to play notes in the extreme bass easily and quickly. The jacks (one for each key) are arranged in pairs and pluck in opposite directions, so that the pairs of jacks are separated by closely spaced pairs of strings. In Italian instruments, each jack passes through a slot in the soundboard and in the solid register or jackslide (about 4 cm by 3 cm) glued to the underside. In North European virginals each pair of jacks is usually served by a single slot in the soundboard, together with another slot below in a thin guide above the keys. Leather on the soundboard and lower guide provides a quiet bearing surface for the jacks.

Although virginals were made in many shapes, the internal bracing is similar for the different types. There is a brace extending from the front to the back of the case at each side of the keyboard; this may be supplemented by corner blocks. A liner around the inside of the case supports the soundboard and carries the hitch-pins; the wrest pins (tuning pins) are held by a larger piece of hardwood. In rectangular instruments a separate diagonal hitch-pin rail and wrest plank are provided. The back corners of rectangular Italian virginals were sometimes cut off as shown by the 1593 virginal by Giovanni Celestini (Donaldson Collection, Royal College of Music, London). A few employ the false inner-outer construction in which a thick softwood case is fitted with cypress veneer and half-mouldings to make it appear as if a cypress instrument were in an outer case. The oldest known such instruments are by Joseph Salodiensis (c1570; see Wraight, ii, p.263) and Celestini (1587; in the Beurmann Collection, Hamburg). By far the most common Italian construction used thin (3–5 mm) cypress case sides with mouldings on the top and bottom edges, as in Italian harpsichords. Many of these thin-cased virginals were kept in a painted outer case.

The case joints of Italian virginals are mitred, as might be expected considering the thinness of their wood; accordingly, it is noteworthy that the corners of the 1548 Karest virginal (fig.2) are dovetailed, even though the wood is scarcely thicker. Otherwise, the structure of the instrument is hardly different from that of an Italian example (compare with fig.1), except for the replacement of the solid Italian jack register by a complete counter-soundboard mortised for the jacks and serving as a lower guide (this feature is also found in a number of German and English instruments, and dovetailing of the case joints in German harpsichords and clavichords persisted into the 18th century).

Later Flemish virginals have thick cases, like those of Flemish harpsichords, and are assembled before the bottom is put on rather than being built from the bottom up. As with the Italian instruments, however, the two principal braces run from the front of the instrument to the back at the ends of the keyboard. The decoration of these instruments normally corresponds to that of the Flemish harpsichords, either plain paint or marbling outside and block-printed papers inside, except for the inside of the lid, which may have a painted landscape on it. A few examples are painted with arabesques instead of being papered, but this must have been relatively uncommon. The inclusion of a Latin motto either on the inside of the lid, on the jackrail, or around the inside of the case above the soundboard was quite common, and this is also seen in German instruments. The case-side covering the keywell (the ‘fallboard’) was usually hinged to the case along its underside. The decorated inside face, sometimes with a motto, was thus displayed when the fallboard was opened.

Virginal

2. Italy.

Numerous Italian 16th-century virginals have survived and show that often considerable trouble was taken to provide elaborate decoration: the 1577 Rossi instrument (Victoria and Albert Museum, London), with inset precious and semi-precious stones is a fine piece of work. More typical was a plain cypress case with fine mouldings, but sometimes the casework was set with intarsia work in contrasting coloured woods, as in the 1523 Francesci de Portalupis virginal (Musée de la Musique, Paris). All of these virginals have a rose in the soundboard, usually made of three or four layers of wood veneer, pierced in intricate gothic or geometric designs. Sometimes carved brackets were set either side of the keyboard. Ivory was sometimes used for the natural-key covers, but boxwood was most commonly used, with ebony-topped sharps. Most instruments by Venetian makers had projecting keyboards, and virginals from the Milan–Brescia area had partly recessed keyboards, but exceptions to these traditions are found in both regions. There is no overwhelming acoustical advantage in one system or the other. Almost all 16th-century virginals have a C/E–f''' compass and later 17th-century examples only C/E–c'''. Early 16th-century instruments were made with an FGA–f''' compass, but in the few instruments that survive the keyboard has since been modified. Some 17th-century virginals (e.g. by Francesco Poggi and Stefano Bolcioni) had split keys for d/e and g/a. Flemish and Italian virginals usually ended on a C/E short octave. A well-known instrument, the so-called ‘Queen Elizabeth’s Virginal’ (in the Victoria and Albert Museum, London; see fig.3), is Italian, probably by Giovanni Baffo. Its original keyboard had a C/Ef''' compass, but a Cc'''d''' (i.e. no c''') keyboard was later installed, presumably in order to alleviate the difficulty of the non-chromatic bass. In turn, this keyboard was later modified to the present G'/B'c''' compass (see Wraight, ii, p.50). English virginals tend to have a wide compass (see §4 below).

Modifications, which have obscured the history of the Italian harpsichord, were not undertaken often for the virginals. It was relatively difficult to replace keyboards with those from other instruments since the pairwise jackslide tends only to match the keyboards for which it was made. Nevertheless, some virginals had their scales changed and keyboards altered to keep them abreast of changing musical requirements.

Considerable discussion has been devoted to the question of the pitch of Italian virginals (see Harpsichord, §2(i), for a detailed discussion): it has been argued that the long scales (usually corresponding to C/Ef'''compasses) were intended for low pitches. Most 16th-century Italian virginals have scales between 30.5 and 35 cm at c'' (with only a few being shorter than this). These instruments were, however, designed to be strung in iron wire, which requires a longer scale than brass wire, and means that this long scale came to a normal pitch (i.e. for 35 cm about a tone below a'= 440).

Although most Italian virginals were designed for iron wire, some were quite clearly intended for brass wire at the same pitch (by reason of their sealing; for further details, see Harpsichord, §1, such as the 1693 instrument by Cristofori (Musikinstrumenten-Museum, Universität Leipzig)). Several rectangular instruments by the 17th-century maker Honofrio Guarracino are examples of the latter. They have the tuning pins on the left-hand side and only one bridge on free soundboard, with the result that the sound is much brighter than that of most virginals and closely resembles that of a bentside spinet. These virginals by Guarracino appear to have been the continuation of a Neapolitan tradition: a similar instrument was made by Alessandro Fabri in 1598 (Tagliavini and van der Meer, 1986). Since instruments of this design are unknown further north of the Italian peninsular, the speculation is permissible that this design might have been influenced by Spanish virginals. Virtually nothing is known of the latter, but Naples was under Spanish administration at that time so the introduction of Spanish instruments would have been possible. In the 16th century the use of brass wire on virginals is believed to have been uncommon, but Isabella’s intarsia virginal was probably so strung; the pitch would have been about a fourth above normal 8' pitch (a' = c415–440).

Italian makers (unlike Flemish makers; see §3, below) all adopted similar scalings and plucking points, thereby giving a fairly uniform character to their instruments. The sound of an Italian virginal is usually louder than that of an Italian harpsichord, since the virginal has two bridges on free soundboard. However, as with all keyboard instruments with a plucking action, it is possible to vary the volume considerably by voicing the plectra.

A few virginals were made with two sets of 8' strings although this was not common. Four such instruments are known: two by Donatus Undeus (1623, Brussels Museum of Musical Instruments; 1633, Kirby Collection, Cape Town), one by Celestini (1594, Museum für Kunst und Gewerbe, Hamburg) and an unsigned instrument attributed variously to Undeus and Celestini (but probably by the latter) in Fenton House, London. Another rectangular virginal, made by Celestini in 1610 (Brussels Museum of Musical Instruments), does not have the usual pairwise arrangement of jacks: instead each string is separated from the next string by one jack. On the nameboard this instrument is described as an ‘arcispineta’. Other Italian makers whose instruments gained a high reputation at the time included Domenico da Pesaro, Vito Trasuntino and Alessandro Trasuntino (no instruments by the latter two makers survive).

Virginal

3. Flanders.

Although the tonal resources of the virginal (which has a single set of strings and is seldom equipped with any means of changing timbre) are more limited than the harpsichord’s, it none the less occupies a crucial position both in musical life and in the development of quilled instruments in general in the 16th and 17th centuries. Harpsichords certainly existed throughout this period both north and south of the Alps, but they are more rarely represented in paintings, drawings etc. than virginals, and it must be concluded that they were much less common than the smaller, simpler and cheaper instrument. In addition, the sound of the virginal is excellently suited to most of the keyboard literature of the period. That the virginal occupied a central position in Flemish instrument building is well illustrated by the fact that in the rules for the admission of keyboard instrument makers to the Antwerp Guild of St Luke (drafted in 1557) the piece of work to be submitted by a candidate was specifically designated as ‘a rectangular or polygonal virginal’ (‘een viercante of gehoecte clavisymbale’) and no mention of harpsichords is made at all. Furthermore, O’Brien (1974) has shown that the Ruckers family made many more virginals than harpsichords.

The earliest surviving Flemish virginal (see fig.2), like those depicted in Flemish paintings from before 1565, is thin-cased and polygonal. These instruments thus bear a superficial resemblance to their Italian counterparts, the most obvious difference being that their keyboards are entirely recessed rather than wholly or partly projecting; however, some Italian virginals of false inner-outer design have completely recessed keyboards. The appearance of a Flemish polygonal instrument seems somewhat heavier than the graceful Italian design. Ripin (1971) has speculated that the Flemish polygonal design was transmitted to the Low Countries by way of Germany. It is known that some of the earliest 15th-century makers working in the Low Countries came from Cologne: of the earliest string keyboard instrument maker in Flanders, Hans van Cuelen (Hans from Cologne; fl 1509–57), little is known, but Joes Karest (builder in 1548 of the oldest surviving Flemish virginal; see fig.2) headed the instrument makers’ petition to the Guild of St Luke in 1557 as they sought to be admitted as instrument makers and not grouped with the painters. A German harpsichord of 1537 made by Hans Müller in Leipzig shows striking resemblances to thin-cased Italian harpsichords. However, the answer as to where these harpsichord or virginal designs originated probably lies in the 15th century, and about this period so little is known in detail that answers can be no more than speculative. As is often the case with inventions, similar designs may have been developed simultaneously in different parts of Europe.

As noted above, however, the guild regulations make it clear that rectangular as well as polygonal instruments were being made in Antwerp in the 1550s, and presumably these instruments were also thin-cased. Although no example from this period survives, the earliest Flemish depiction of a rectangular virginal (an engraving by Cornelis Cort printed in 1565, based on a painting by Frans Floris from ten years earlier, now lost) shows an instrument without a lid, suggesting that it was thin-cased and intended to be kept in a stout outer case like an Italian instrument. By the end of the 1560s, however, it would seem that a thick-cased rectangular instrument very much like those now considered typically Flemish had come into being, since a painting by Michiel Coxcie purchased by Philip II of Spain in 1569 clearly shows an instrument of this kind, which seems immediately to have superseded the thin-cased types in the Low Countries.

At the end of the 16th century, three types of virginal were being made in Flanders: one with the keyboard centred in one of the longer sides (fig.4), one with it placed off-centre to the left (called ‘spinett’ by Claas Douwes; see fig.5), and one with it placed off-centre to the right (‘muselar’; fig.6). The centre-keyboard design in normal-pitch virginals is known only from one instrument, that made for the Duke of Cleves (fig.4), and it is impossible to say whether this was an isolated example or whether it was a design that was later forgotten. Octave (4') instruments retain their central placement of the keyboard, although this is virtually obligatory because of their small size. The difference in the placement of the keyboard is important since it determines the placement of the jacks in relation to the two bridges. With the keyboard placed to the left, the jacks run in a line close to the left-hand bridge; therefore the point at which the jacks pluck the strings is close to the mid-point in the treble and well away towards the left end in the bass. This is also true with virginals with centrally-placed keyboards, although the displacement of the plucking point from the centre of the strings in the bass is reduced (see fig.3). Because of this varying plucking-point, the timbre of these virginals gradually changes from flute-like in the treble to reedy in the bass, being similar in this respect to the timbre of a harpsichord. Muselars, with their keyboard at the right, have their strings plucked at a point near the centre for virtually their entire range, producing a powerful, flute-like tone that varies little from treble to bass. Both spinetten and muselars were made in a variety of sizes, the smaller ones presumably tuned to higher pitches and the smallest ones clearly tuned an octave above the largest ones. Among the surviving instruments, muselars are more numerous in the full-size examples, spinetten in the smaller sizes.

The earliest surviving example of a muselar is by Hans Ruckers (d1598) and is dated 1581 (fig.6); it is entirely possible that Ruckers invented the muselar design, even though it must be emphasized that the other characteristics now associated with Ruckers’s work are to be found in virginals made by the preceding generation of makers, notably Hans Bos and Marten van der Biest. Muselars always have both their bridges resting on free soundboard in contrast to the spinetten and the polygonal instruments, which often appear to have had the bridge at the left deadened by a plank underneath the soundboard. Ruckers’s practice in this regard was not consistent; the smaller spinetten all seem to have the left-hand bridge deadened, but some of the full-size examples have both bridges resting on free soundboard. Muselars have the further distinction of being the only virginals normally provided with any means of changing timbre. A substantial number of the surviving examples have an Arpichordum stop, which may be engaged to produce a buzzing sound in the tenor and bass to contrast with the clear flute-like sound of the alto and treble. (For a detailed discussion of surviving Ruckers instruments, see Ruckers, §2.)

The culmination of the Flemish virginal makers’ art was the double virginal called ‘mother and child’ by Joos Verschuere-Reynvaan (Muzijkaal kunst-woordenboek, 2/1795), a usage apparently sanctioned by the makers, since the original Ruckers numbers on surviving examples include an ‘M’ and a ‘k’ for moeder and kind on the large and small instruments respectively. These instruments consisted of a virginal of normal size (the ‘mother’) with a compartment next to its off-centre keyboard in which a removable octave instrument (the ‘child’) was housed. The octave instrument was designed to be coupled directly to the larger one. An oblique slot was cut in the bottom of the octave instrument, and if the jackrail of the ‘mother’ was removed and the ‘child’ was put on top of it in place of the jackrail, the larger instrument’s jacks reached through the slot to touch the underside of the octave instrument's key-levers. Thus when a key of the ‘mother’ instrument was depressed its jack pushed upwards on the back end of the corresponding key of the ‘child’, causing the octave instrument to sound at the same time as the larger one. In addition, the octave instrument could be played separately, either when in place on top of the larger instrument or entirely removed from it. Instruments of this kind appear to have been imitated in Germany and Austria, and an Innsbruck inventory made in 1665 mentions a virginal in which two smaller ones were contained, ‘all three of which could be placed on one another and sounded together’.

Virginal

4. England and other north European countries.

Unlike some Italian and Flemish examples, the surviving English virginals are all rectangular in shape. Their cases are typically of oak, and the lids were always originally vaulted. The decoration is also standardized: the outside of the cases are plain, ornamented only by ironwork strap hinges and locks; but the insides are given stylized and colourful embellishment including paintings on the lid and fallboard generally of landscapes with figures, painted decorations on the soundboard, and gilt embossed papers contrasting with finely cut mouldings, normally of cedarwood, sometimes painted. The natural keys are usually boxwood, with dark sharps, occasionally inlaid, although instruments survive with snakewood or ebony naturals and solid ivory sharps. The compass of early virginals is often from C to c''', later instruments usually having a very wide G'/B'–f''' compass, although three instruments from the mid-1660s have compasses extending down chromatically to G' or below. The short scalings, often based on a c''' string length of 6 inches (15·24 cm) suggests many instruments were strung in iron at a high pitch standard, probably one or two semitones above a' = 440. Other instruments were built to pitches one or two semitones below this high pitch and there is one instrument, the orphan of a mother-and-child virginal made by Thomas White (c1600–60; the only such instrument known to be made in England), which was designed to play a 5th above the standard high pitch.

The virginal in England probably developed in the early part of the 16th century, influenced by early instruments from Flanders and the Spanish Netherlands. There are many references to virginals in this period, including several in the inventory taken at the death of Henry VIII in 1547. Although a number of these were probably made on the Continent, about 20 virginal makers are known to have worked in Britain in the 16th century. The typical layout and decorative scheme found in the surviving instruments were most likely established by the last quarter of the century.

The surviving instruments date from 1638 to 1684, although two undated examples are probably earlier. The White family appear to be the most prolific of the early makers judging from surviving examples. Five of Thomas White's instruments have survived, including an unusual instrument with double stringing from G'/B' to A, then single strung to f'''. His son James has left two instruments. Later virginal makers of note include Stephen Keene (c1640–1719) and John Player (c1634–c1706), who both went on to make spinets, Adam Leuersidge (fl 1650–70), and the Exeter makers John Loosemore (1613–81) and Charles Rewallin (fl 1657–97). Loosemore, Rewallin and James White were also involved in making or repairing organs.

Praetorius (Syntagma musicum, ii, 2/1619/R), who also mentioned placing virginals on top of one another, depicted a rectangular instrument differing in several respects from the developed Flemish design, rather resembling pre-Ruckers examples in having a central keyboard and a jackrail supported at the left by an arm extending from the bass end of the key-well. The instrument shown by Praetorius also has a larger range than the regular Flemish virginal compass of four octaves with a bass short octave (C/Ec'''), its keyboard extending to d''', with divided accidentals in the lowest octave to provide the F and G not ordinarily available with the C/E Short octave, as well as having the E keys divided in the remaining octaves to sound D, thereby extending the range of available keys to include E major and E minor. As with virtually all north European virginals, a tool box is set in the space to the left of the keyboard.

Although north European polygonal virginals were normally housed in outer cases like their Italian counterparts, this does not seem always to have been true of the rectangular instruments. Praetorius did not show a lid for the instrument he illustrated (presumably to save space), although the presence of a hinged front board to cover the keys strongly suggests that the instrument had one; it would be of great interest to know whether such a lid would have been vaulted like those shown in French illustrations of the 1580s, on the title-page of Parthenia (London, 1612–13; fig.8) and found on all surviving English virginals, which range in date from 1641 to 1679. Despite the fact that the English instruments seem to be patterned on Flemish spinetten, the vaulted lid, the method of supporting the left end of the jackrail and the shorter scaling of English virginals (fig.9) suggest that they actually derive from the same non-Flemish tradition represented by Praetorius's illustration and the surviving 17th-century harpsichords and virginals from Germany and France – a tradition also represented by the polygonal Flemish virginals from the mid-16th century.

Outside Italy the making of rectangular virginals seems to have come to an end by the close of the 17th century, these instruments having been replaced by bentside spinets. Since only one bridge of a spinet is on free soundboard, the sound of a spinet resembles that of a harpsichord, and it may be for this reason that taste changed in favour of the spinet and against the virginal. Although the spinet is typically somewhat smaller than a rectangular virginal, the scalings employed in both instruments are similar. Polygonal virginals and spinets usually have less soundboard area in the low tenor and bass than rectangular virginals; this can impart a clearer, reedier character to the sound but, as in all keyboard instruments, it is the skill of the maker that ultimately influences the quality of the sound. Some virginals were made in the early 19th century in Italy: they resemble square pianos in appearance, but contain a plucking mechanism. The last dated of these (1839, now in the Musikinstrumentum-Museum, Leipzig University) is by Alessandro Riva of Bergamo.

The importance of the virginal has been exaggerated by some, who, unaware that the term was used for all plucked keyboard instruments in England, assume that the music of Byrd, Bull, Gibbons, Tomkins and others was intended specifically for these single-strung instruments. However, as is made clear by the title-page illustration of Parthenia In-violata or Mayden-Musicke for the Virginalls and Bass-Viol (c1624–5), which shows a harpsichord rather than the rectangular instrument of the earlier version of Parthenia, the music of the ‘virginalist composers’ was not intended to be restricted to the virginal. Other writers have relegated the instrument to a status rather lower than that of the modern upright piano. The proper assessment of the virginal lies between these extremes. Despite the limitations imposed by a single register, virginals are useful and remarkably versatile instruments with special qualities of their own, on which virtually the entire literature of their period can be played with considerable success. Thus, although virginals were often used merely as practice instruments and for domestic music-making, they should not, like the spinet, be thought of essentially as substitutes for the harpsichord.
