One of the things I love about the internet is it has opened up a lot of opportunities to create music that didn't exist before and in fun ways that even non-musicians or people who can't read music can still have fun making sounds. I'd like to share a trio of them with you today.
Auditorium is the most beautiful and challenging of the three. Change the location and size of the gravitational pulls to activate each portion of the composition.
Ball Droppings has a lot of potential if you want to take the time to fine tune it. Balls drop and you draw lines. When the ball hits a line, it plays a note corresponding to the amount of force it had when it struck the line.
My favorite, though, is Andre Michele's Tone Matrix. A very simple synthesizer but a complete blast to make music with.
