About this piece

Chameleon is an eight-minute piece for six cellos, composed for the Dulwich International Music Academy and first played in Beijing on 28 June 2014. Taking the colour-changing lizard as its image, it uses slow glissandos in every part so that the harmonies gradually morph into one another, with major triads briefly coming into focus out of dissonant clusters. The first cello works as a soloist and twice climbs high into the treble register. The composer has also arranged it for string quartet and for trombone septet.

Technical overview

The first cello carries a sustained solo line that climbs in treble clef into thumb position. The five lower parts, which are noticeably easier, hold slow glissandos between harmonies, sweep through natural-harmonic arpeggios and play rolling slurred arpeggios and plucked chords.

  • Expressively adjust intonation for chord balance.
  • Handle fast runs and large leaps precisely.
