How is sound produced in your straw flute?

Sound is produced in a straw Flute when air is blown across the opening at one end of the straw, creating vibrations in the column of air inside. The pitch of the sound is determined by the length of the straw and the placement of finger holes, which alter the effective length of the vibrating air column. When the holes are covered or uncovered, the frequency of the vibrations changes, producing different notes. Essentially, the movement of air and the manipulation of the straw's length create musical sounds.
