As a professional double bassist with a major symphony orchestra, a significant amount of his creative effort has been spent on works which feature the double bass. He has written works for double bass and orchestra, for solo bass, bass with accompaniment, two sets of bass duets, and several chamber music works. He won the 2004 International Society of Bassists Composition Competition for solo double bass with his work entitled Vision Quest, for double bass and piano. It was premiered in 2005 at the ISB conference in Michigan.
At the keyboard, Stallcop has been active in classical music, free improvisation and the performance of his own music.

His recordings are available on CDBaby, I Tunes, Spotify, and other online sources.
