Auskomponierung

(Ger.).

In Schenkerian analysis (see Analysis, §II, 4–6), the elaboration of a given contrapuntal-harmonic plan. The term is often rendered in English as ‘composing-out’, but ‘elaboration’ is a common alternative. The process of Auskomponierung begins with the tonic triad; its initial elaboration produces the Ursatz comprising a conjunct descending Urlinie supported by a I–V–I bass Arpeggiation (ii). At subsequent structural levels (see Layer), various techniques of Prolongation are applied.

‘Composing-out’ is sometimes used more generally, in a non-Schenkerian context, to mean the working-out of the implications of some special feature of a piece; for example the C in the seventh bar of Beethoven's ‘Eroica’ Symphony may be said to be ‘composed-out’ when it is interpreted as D in the recapitulation of the first movement.
