AC’s Turning refers to the turning signal equipped on busses used by AC Transit in the Bay Area. The motive is an alternating major second, heard in the French Horn at the beginning of the piece. Having used public transportation often as a student in the Bay Area, I used this melody, motive, as the source of many whistled and hummed spontaneous inventions to creatively pass time on the bus. Movement, with occasional stops and starts, is another important concept connecting this piece with the image it represents.
