About this piece

A short, loud trio for three cellos (the score calls it 'a loud cello trio'), composed in October 2012 and recorded by the composer, who played all three parts, in December 2017; it later appeared on his album The Ageless Gate. It is built over a driving quarter-note ostinato at quarter = 140 in the lowest cello, with long sustained lines above and a punchy middle section of short staccato figures. Alternative violin and viola parts are included, so the top lines can also be taken by upper strings.

Technical overview

All three parts stay in bass clef with ledger lines: the top part sustains whole and half notes up to A4, the middle part reaches G4, and the bottom part repeats double stops against the open C and G strings before climbing a scale to G#4; the middle section needs crisp, together staccato eighths.
