{{anchor|SchubertOp4no3}}<!-- This section is linked from [[Schenkerian analysis]] -->Unfolding (''Ausfaltung'') is an elaboration by which several voices of a chord or of a succession of chords are combined in one single line "in such a manner that a tone of the upper voice is connected to a tone of the inner voice and then moves back, or the reverse".<ref>''Free composition'', p.&nbsp;50, §140.</ref> At the end of Schubert's ''Wanderers Nachtlied'' op. 4 no. 3, the vocal melody unfolds two voices of the succession I–V–I; the lower voice, B{{music|b}}–A{{music|b}}–G{{music|b}}, is the main one, expressing the tonality of G{{music|b}} major; the upper voice, D{{music|b}}–C{{music|b}}–B{{music|b}}, is doubled one octave lower in the right hand of the accompaniment:

In his later writings (from 1930 onwards), Schenker sometimes used a special sign to denote the unfolding, an oblique beam connecting notes of the different voices that are conceptually simultaneous, even if they are presented in succession in the single line performing the unfolding.<ref>For a detailed study of "unfolding", see Rodney Garrison, ''Schenker's ''Ausfaltung'' Unfolded: Notation, Terminology, and Practice'', PhD Thesis, State University of New York at Buffalo, 2012.</ref>
