Music icons

Attached are samples of the style of logo's we're looking for... very primitive with just a few correctly-placed lines to get the message across. The attached icons are examples we're considering using for the clarinet theme, the violin theme, the film music theme and the piano theme. Other themes we need: - trumpet - trombone - horn - flute - saxophone - bassoon - guitar - harp - accordeon - singing - children (child's face) - literature (open book) - percussion - jazz & blues (stylized "J & B") - harmonica - orchestra/ensemble - keyed instruments (piano, organ, keyboard... design could be a few black and white keys) - (maybe a few more...) I'll need the images in vector format (CDR, AI). The illustration should be drawn as lines of a given thickness; the background circle as a separate object such that I can change it's color afterwards.
