DESCRIPTION: Kin'Ya Takahashi --- The function of the register hole of the Clarinet can be basically \nexplained from the common property of two delay systems (J. \nPhys. Soc. Jpn, Vol.83, 124003 (2014)). Namely, if the strength of \na short time delay is sufficiently small but non-negligible, the \nthird harmonic is well sustained over a wide range of the short \ndelay time. This fact indicates that the register hole with a small \nradius raise the pitch of the first register notes in a wide range \nmore than an octave to the second register notes by a twelfth \n(19 semitones). However, the reflection function has many delay \npeaks even when only the register hole is opened. That is, the \nclarinet should be characterized as a multi-delay system. In this \npaper, we focus on the effect of a very short time delay, which \ncharacterizes the reflection from the discontinuity in the \nmouthpiece. We numerically found that the function of register \nhole survives even for such a three delay system including the \nreflection from the mouthpiece.\n
