In Sympathetic (2016), for bass clarinet and marimba with live electronics, it becomes difficult to distinguish between the original sound and its sympathetic response. Both musicians play similar gestures which sometimes dovetail and increasingly overlap. The electronics act like a set of sympathetic strings, but each "string" has been processed independently so that each note triggers a different sound.


Emerging composer and improviser Joshua Hahn has been presented by Boston Musica Viva, Nonevent, East Coast Contemporary Ensemble and Da Camera of Houston. Joshua’s music starts with the instruments. He relishes the thought-provoking, often unexpected results of reaching a unique musical solution for every instrumentation. He often applies his background in engineering to craft exciting, integrated electro-acoustic works.

An active composer and improviser in Boston, Joshua Hahn is completing a commission for Trio Notturno and plays with Inedit sound and movement ensemble. In the past year his works have been premiered by Red Hedgehog Trio, Vox Novus Fifteen Minutes of Fame, and Madera Winds. He has ongoing improvising collaborations with Dan Sedgwick, piano and James Coleman, theremin, and has been presented as an improviser by Opensound, Nameless Sound, Nonevent and Washington Street Art Center.

Joshua is a freelance musician who has appeared with the Pro Arte Chamber Orchestra Wind Quintet (flute), Tufts New Music Ensemble (flute and electronics), Greek Music Ensemble/Berklee Performance Center (nay) and in the US premiere of Stockhausen's Stop with the Harvard Bach Society Orchestra (synthesizer and electronics). He teaches western flute privately at Focal Chinese Music.

Joshua holds a BA summa cum laude in music from Tufts University and an MM in composition from Rice University. His major teachers have included John McDonald, Shih-hui Chen and Anthony Brandt. He is the current Operations Manager at both Symphony Nova and Pro Arte Chamber Orchestra of Boston.
