I wrote this piece for trombone and piccolo on May 17, 2013 in Los Angeles, CA. The conceit of it is that the trombone and piccolo each play the same long phrase, in their own register, but with different rhythms and starting times. In other words, they are saying the same things in different ways.

The piece was premiered in 2023 by Mariaceli Navarro (Piccolo) and Alonso Olvera (Trombone) under the Piccolegio Youtube channel:
