Former Apple engineer Kelly Jacklin writes about how the Apple iPhone’s “Tri-tone” sound was created in the late 1990’s on his website at http://jacklinstudios.com/docs/making-of-158-marimba.html
At the time, Kelly Jacklin was trying to come up with a sound for SoundJam software (the software that would eventually evolve to become iTunes) to alert when a CD was burnt and came with several sounds (you can listen to the other sounds that weren’t chosen), including the now famous Apple Tri-tone sound.
