Keypad music!!

[Calleja]

I just got sent this:

And it really works!!

I figure... there's gotta be more songs you can sort-of-play with the keypad... do you guys know any?

I used to do this all the time with little kids songs like mary had a little lamb or london bridge.

Interesting factoid: Telephone tones use a scheme called DTMF (dual tone multi frequency). Basically they use two tones to make up the sound for each button. On some older handhelds, pressing two buttons at once would cause one of the frequencies to drop out, so that you would get a pure tone, which made phone music much more enjoyable

I'm going to set that number up as a sex chat line and make millions.
