Experimental results when playing chromatically on a diatonic harmonica

Résumé

One can play chromatically on a diatonic harmonica by using different playing modes: normal playing, bends and overnotes (overblows and overdraws). For each playing mode, the reed motions were measured with strain gauges and the inner pressures were recorded at the same time with a differential pressure transducer. The reeds motions were shown to be sinusoidal. The control of active reed motion(s) on the evolutions of the inner pressure was underlined. The internal mechanisms occurring during the playing were systematically analyzed. Modeling of the reeds operation was derived and explanations for the harmonic content of the sound is given.
