Sequenza

From Wikipedia, the free encyclopedia

Sequenza is the name borne by several pieces of music for solo instruments by Luciano Berio. The word "sequenza" means "sequence" in Italian. The pieces, which often call for extended techniques, are:

• Sequenza I (1958) 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) for oboe (reworked as Sequenza VIIb for soprano saxophone)
• Sequenza VIII (1976) for violin
• Sequenza IX (1980) for clarinet (reworked as Sequenza IXb for alto saxophone and 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

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; and Sequenza VIII became Corale.

Conversely, Sequenza IX had grown out of a piece for clarinet and electronics which Berio later withdrew (this original piece was known as Chemins V; it is a different piece to the one now known by that name).
