According to the concert programme in the BSO archives, the concert containing the premiere of Triad IIa was broadcast. However, no tape has survived.
Triad II is one of a group of pieces related not so much by musical gestures as by similarities of formal articulation. In the present work the emphasis is upon the constant re-ordering of a number of simple elements heard at the opening; in the course of the three sections they undergo variation and expansion as well as reorientation relative to one another.
Percussion: vibraphone, 5 chinese blocks, 3 chinese tam tams, 2 timpani, side drum, 3 suspended cymbals, bass drum, small gong.
Pianist plays also: tam-tam, bass drum, small brass bell. The piano's lid should be removed.
