Multiphonics

I notated my multiphonics using a transparent rectangle to represent the dominant frequency, while the subsequent frequencies were notated using black noteheads. If additional oscillations in the multiphonic required their frequencies to be notated, I added up to two more notes to the chord, which was notated using a smaller, light grey notehead. Where necessary, I have added comments about the position of my embouchure on the reed. As each player plays differently and on different reeds, the dynamics of a multiphonic can be variable, so a composer must work with the player. For this reason, I do not write the dynamic range, but I do write when a multiphonic is fragile. The number system I used relates to the pitch centre I heard when I first played the multiphonic which did not necessarily correlate later to the spectral analysis. This meant the number 0 = a pitch centre of a/b flat 1 the pitch centre of B 2 the pitch centre of C and 3 the pitch centre of C an octave higher etc. This was not the case. The transparent rectangle represents the main frequency.

This is the same fingering as the multiphonic above but I played on the tip of the reed to produce this.
