Tuned bottles

Tuned Bottles are musical instruments crafted from everyday bottles (found objects) which are filled with water to create different pitches. The length of the air column above the water determines the resonant frequency, and thus the pitch achieved. Tuned bottles may be struck (placing them in the percussion family), or blown (placing them in the wind instrument family, similar to pan-pipes). In the latter case, they are often known as blown bottles.

The instrument has the potential range of at least one octave, and can easily be tuned to any chromatic pitch, so it is possible to perform complex melodies with it. Typical struck bottles sound from about C7 to C8. Of course, music can be transposed into this range as needed. The pitch, dynamic range, and timbre depend on the bottles used, for example their material, shape, thickness, and so on.
