This essentially is a long melody, to be played by solo cello, viola or violin, or any combination of the three (or possibly more than three). The cello and viola are an octave apart, and the violin a fifth above the viola. Each instrument therefore plays on the equivalent string with the same finger at all times. There are lots of glissandi, which need to be very carefully controlled - tuning matters!! Much of the string playing technique is influenced by the Indian sarangi…
