To make melodies , one plays it high into the overtone series .. melodies. melodies. overtone series. harmonic series ( music ). One series of harmonics is achieved by overblowing with the end of the tube open and another is achieved with the end closed .. overblowing. overblowing. This means that most overtone flutes are limited to producing only those notes from a natural scale .. natural scale. Harmonic series ( music ). Overtone flute tubes typically have relatively long resonating chamber compared it its diameter or cross sectional area , which encourages the instrument to resonate in the higher harmonics .. flute. flute. resonating chamber. resonator. cross sectional area. cross section ( geometry ). This also makes it either difficult to play or very quiet when attempting to play the instrument in the first harmonic .. harmonic. harmonic
