William Rivard's Quadrivalence for bass trombone was composed for and dedicated to Randall Hawes.
The musical style is derived from the 12-tone school. Dr. Rivard makes excellent use of modern brass performance techniques such as singing while playing, improvisation, and full use of the range of the bass trombone.
I highly recommend this piece; great for recitals!

I cannot be objective about Quadrivalence since it was written for me by my college teacher, William Rivard. However, being somewhat knowledgeable about the repertoire choices out there for the college player, I'd say that this is a challenging but very rewarding piece to perform. A few avant-garde techniques are needed such as singing and playing and making doink sounds but it's nothing too difficult. It is in four sections (Valence; the make up of an atom) includes some improvisation and wide interval leaps.
I am forever grateful to Wesley Jacobs for publishing this piece and making it available.
William Rivard passed away in 2008, and this is a wonderful testimony to his memory.
