Martin introduces edgy and exhilarating improvisational singing games and forms to high school choruses, church & community choirs, workshop gatherings, and retreat participants. 

Beginning with the simplest forms of single and duet improvisation, Martin builds skills in give-and-take, language creation (scat singing), motor/riff development, harmonic variations, section movements, soloing, finally leading to full group improvisation and performance models. 

Martin has trained with such musical luminaries as Rhiannon (long-time Bobby McFerrin co-performer), Ysaye Barnwell (Sweet Honey and the Rock) and Moira Smiley (International vocalist and teacher) and countless hours in self-guided exploration. He is a founding member of a cappella improv ensembles, ImproVox, Hot Buttah! and BRIO! 

The workshop coordinator for the Harmonium Choral Society of New Jersey exclaims,  "Martin, these are the most consistently high scores I’ve seen in the 3 years I’ve been coordinating. 19 fives (top evaluation score), 1 four, nothing lower!  Also 1 SIX!!! - not even ON the form! The responses from the participants were consistently the most enthusiastic I’ve seen. Thank you once again for a most enjoyable experience."
