Christopher Willits is a musician and multimedia artist located in San Francisco. His musical focus is characterized by guitar with computer software processing and improvisation, which generates a large palette of possible sounds including; melodic rhythms, grainy textures, and smooth drones. Willits' music is electroacoustic in nature, in that both analogue and digital worlds are fused into one. Willits coined[citation needed] the term "folding guitar" in press releases and interviews surrounding his 2002 release Folding, and the Tea. Willits' guitar lines and harmonies are folded into each other using custom-designed software. As described on his website; "notes and phrases hook and weave, creating complex patterns of interlocking rhythms, melodies and textures".
