This musical instrument produces sound when a stream of air directed across a hole in the instrument creates a vibration at the hole. The air stream creates a siphon effect which excites the air contained in the cavity called resonator. Different pitches of the sound are created by opening and closing holes in the body of the instrument. By varying the air pressure, a flute player can also change the pitch of a note by causing the air in the flute to resonate at a harmonic other than the fundamental frequency without opening or closing any holes. The sound of flutes can be increased by creating larger holes on the body of the instrument.
When buying a flute there are certain things to look for. Beware of leaks. Leaks are usually caused by air leaking out of the flute between the pads and the tone holes. You should be able to play easily with good sound all the way to low C without pressing hard on the keys. The lowest octave of the flute is where leaks or adjustment problems are most easily detected.
