Composing Music with Sound Matrix

For composers, musicians, and music enthusiasts, then the Sound Matrix Flash game could be your new favorite Internet toy. I’ve definitely wasted more than my share of time goofing around with it! 😀

How to Use Sound Matrix


When you load up the game, you are greeted with the above blank gray grid on a black background.


Clicking any gray square on the grid turns it white; the white square will produce a tone every so often. In the above example, this white square produces a B natural approximately every 3-4 seconds, and the little white square lights up when “struck,” such that the whole grid sparkles with it. Very pretty! 😀


For those who might be interested, I came up with the complete musical scale that Sound Matrix can produce. (The uppermost squares produce the highest tones; the lowermost squares produce the lowest.) While this may not look like the most diverse scale, it can actually create quite a variation of tunes!

As for actually composing tunes, clicking squares that are an equal horizontal distance apart will give you a “beat,” which will loop every few seconds. That’s pretty much all you need to know–the rest is just experimentation, play, and happy accidents! 🙂

A Few of My Sound Matrix Compositions

These are a few little tunes I came up with while musing and playing; I had a ton more saved, but I lost them in the Great Hard Drive Crash of 2011. :/ But where those came from, there are plenty more 🙂 The following screenshots kind of serve as “sheet music” for Sound Matrix:


“Celebration in A Major”


“An E-Z Groove”


“Latin Dance in B Minor”


“Triplets in E”


“Fast Club Jam in B Minor”
