Peruvian Pan Flute — 7 Tube

The 7-tube pan flute is the most elemental form of the instrument, its range spanning a single Andean pentatonic octave that has been in use since pre-Columbian times. Every tube is open at one end and sealed at the other, its pitch determined entirely by length — a perfect illustration of the physical law connecting dimension to frequency that Pythagoras encoded as the basis of harmony. Small and light, it requires only breath and attentiveness to produce music of quiet beauty.
