We've included two octaves of .wav files in the key of F.
The leftmost bottle (as you look from the front) is the tonic, and the next 7 bottles go up through the scale. Bottle #8 plays F again, one octave up.
Bottle 9 (the rightmost bottle) acts just like a thumb hole on a recorder. When you touch this bottle, all the other bottles will play a note that's one octave higher. This gives you two full octaves plus a high F -- plenty of notes to play melodies in a major or minor key.
Bottle 10 is my off switch. Touching this bottle will make all the bottles go dark.
Bottle 11 starts "demo mode". We've included 3 .wav files that play short melodies. Touching this bottle will cycle through the three melodies, and play an accompanying LED animation too.
