Craig Leonard is an artist and musician living in Halifax, Nova Scotia. He has exhibited work nationally and internationally and most recently was included in the "Oh Canada" exhibition at Mass MoCA in North Adams, MA, which runs from May 26, 2012 to April 1, 2013. His band Catbag (with Mitchell Wiebe and Dave Ewenson) released the album Bunker Junker (Electric Voice Records) in June 2012, while his project Guilt (with Matthew Grimson) released its self-titled album in March. He has taught Intermedia at the Nova Scotia College of Art & Design since 2006 and will be a visiting artist at CalArts in fall 2012. Craig's "A Colour-Coding of Partch's Ptolemy Keyboard Based on his Chromelodeon 1" transfers the arbitrary colour scheme used by the American composer Harry Partch for the Chromelodeon I, a microtonal keyboard he constructed in 1945, to Partch's preliminary instrument, the Ptolemy. The only record of the Ptolemy is a black and white photo. This colour print represents one 'octave' (comprised of 43 distinct notes) of the Ptolemy keyboard as it might have appeared if given the same colour-coding as the Chromelodeon I. The original Ptolemy was misplaced by Partch sometime in the 1940s.
