 The overtone flute is the ancestor of all flutes! Having no finger holes, the notes are made by altering the pressure of the breath. Therefore, all notes are from the natural overtone (harmonic) series, rather than from the conventional musical scale. THE OVERTONE (HARMONIC) SERIES: In technical terms, "the overtone (harmonic) series" is a combination of a fundamental tone (first partial) together with overtones (harmonics/partials) which are upper tones generated from the fundamental tone. Overtones occur in a fixed sequence (remember that the human ear will only hear some of them). This fixed sequence is known as the overtone (harmonic) series. The first twelve notes of the (theoretically infinite) overtone series are illustrated below in relation to a fundamental tone of "C". C C G C E G Bb C D E F# G or in numbers: 1 1 5 1 3 5 b7 1 2 3 #4 5 |
