Here are free MP3 files of the musical notes. Listen to each pitch, hear the scale, tune your instruments. Feel free to sample, mix, scratch, and mashup the sounds of the various notes from A3 to E5. Each MP3 file is 1 minute long.
When and if you come up with clever uses for these files, please tell me jetcityorange at gmail dot com I’m just curious. Yes this page is an online tuning fork but what else are you doing with these files?
