# Sequenza

Sequenza (Italian for "sequence") is the name borne by fourteen compositions for solo instruments or voice by Luciano Berio. 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Conversely, Sequenza IX grew out of a piece for clarinet and electronics (later withdrawn), originally known as Chemins V; NB it is not the same as the work with the same title which originates from Sequenza XI.
