Variations on a Byzantine Christmas Chant

[for Buchla-Piano Bar and max/msp]

composed 2011: 10 minutes

The piece requires the use of a Buchla “piano bar”— a device that sits along the top edge of the piano keys and allows for a traditional acoustic piano to function as a very sensitive midi controller.  So, while the piece does employ many of the classical approaches to melodic and harmonic variation, there is the additional dimension of timbral variation made possible by the computer.    As live performance “data” is detected (sound from the microphone and midi data from the Buchla Bar) it is passed along to a max/msp patch, which enhances and varies this performance input in a variety of ways.  Variations on a Byzantine Christmas Chant is included on my 2012 CD, Winter Nocturnes.
