Sequenza (Italian for "sequence") is the name borne by fourteen compositions for solo instruments or voice by Luciano Berio.1 The pieces, some of which call for extended techniques, are:
- Sequenza I (1958; rev. 1992) for flute
- Sequenza II (1963) for harp
- Sequenza III (1965) for female voice
- Sequenza IV (1965) for piano
- Sequenza V (1966) for trombone
- Sequenza VI (1967) for viola
- Sequenza VII (1969/2000) for oboe (reworked as Sequenza VIIb for soprano saxophone in 2000)
- Sequenza VIII (1976) for violin
- Sequenza IX (1980) for clarinet (reworked 1981 as Sequenza IXb for alto saxophone, and 1980 as Sequenza IXc for bass clarinet)
- Sequenza X (1984) for trumpet and piano resonance
- Sequenza XI (1987) for guitar
- Sequenza XII (1995) for bassoon
- Sequenza XIII (1995) for accordion
- Sequenza XIV (2002) for cello (reworked in 2004 by Stefano Scodanibbio as Sequenza XIVb for double bass)
Several of these pieces became the basis of larger works:
- Sequenza II, with the addition of extra instrumental parts around the original solo, became Chemins I.
- Sequenza VI developed into Chemins II, Chemins IIb, Chemins IIc and Chemins III.
- Sequenza VII became Chemins IV.
- Sequenza XI became Chemins V.
- Sequenza X became Kol-Od, also known as Chemins VI.
- Sequenza IXb became Récit, also known as Chemins VII.
- Sequenza VIII became Corale.
Conversely, Sequenza IX grew out of a piece for clarinet and electronics (later withdrawn), originally known as Chemins V; NB it is not the same as the work with the same title which originates from Sequenza XI.
