Some potential see here I. A few ideas. Add drum sounds. Make it a circle: distance from center will be the pitch, and an arrow moving clockwise will be the time. Allow to draw lines: when such a line crosses a pitch circumference, it will make a sound. Line color will be instrument type. The time arrow will keep revolving around the center, playing the pattern over and over. You'll basically draw music this way.
