Trevor Bock - 4-Note Bottle Blowing Instrument

I have always loved the angelic sound that is produced by blowing into an empty glass bottle. The combination of wind noise and the ringing sine wave tone that resonates out of the bottle creates a fascinating timbre that is impossible to perfectly replicate digitally. What if you could mechanically create this sound and produce beautiful melodies to perform with it? This is
what inspired me to create the 4-Note Bottle Blowing Instrument. This device contains four small fans attached to DC motors mounted in a specific way to effectively blow air into each of the bottles. This causes them to resonate and create a fairly loud sine tone. Each bottle is individually tuned by raising and lowering the amount of water inside them. Using an Arduino, the instrument will then perform a sequence of notes by fading the fans in and out from left to right. This allows musicians to tune each bottle accordingly and create any four-part melody they desire.
