A new abstract oil on canvas

This is my latest creation. I wanted to paint a cheerful looking piece for a long time and this one caught my eye. I loved the way the colors, shades and shadows come into play and most of all love the music instrument theme.  I used an unframed canvas sheet so it could be some time before it goes on the wall. I'd love to get some feedback on this - actually thought of asking my husband but what does he know about music :P
