Boomwhackers & Chroma Note

It is adaption of the earlier Rainbow system that gave notes of the musical scale a relative colour from that of the rainbow. The Chroma Note system is as follows C - Red, D - Orange, E- Yellow, F - Light Green, G - Dark Green, A - Purple, B - Pink, C - Red. The incidentals (Sharps and Flats) are also given colour values inbetween those of the whole notes.
