This piece is aleatoric. The pianist sets the pulse for the piece from their entrance at 0:40. Players play the sections in boxes until cued by the pre-recorded track. Be sure you are certain of the pianist's pulse before moving on to the next section. Players should also complete the previous section before moving on. At about 6:00, the aleatoric section ends. The final section of humming should be in unison.
TheTree is dedicated to the memory of my dear sister, Susheela Sankaram, who passed away on 9/19/19 at the age of 39.
