Demisemiquaver

Thus they call a double whole note a breve, a whole note a semibreve, a half note a minim, a quarter note a crotchet, an eighth note a quaver, a sixteenth note a semi-quaver, a thirty-second note a demisemiquaver, and a sixty-fourth note a hemidemisemiquaver, or semidemisemiquaver. ❋ Henry Louis (1921)

Remember, you've got to begin on the demisemiquaver at the end of the bar -- only not too staccato, remember -- and allow for the pause. ❋ William Frend De Morgan (1878)

But you must not vigorously move immediately from semiquavers to demisemiquavers, as in this example, or from these to the next in degree -- that would be doubling the velocity of the shake all at once, which would be a skip, not a graduation; but you can imagine between a semiquaver and a demisemiquaver intermediate degrees of rapidity, quicker than the one, and slower than the other of these characters; you are therefore to increase in velocity by the same degrees in practising the shake, as in loudness when you make a swell. ❋ George Hart (N/A)

OH MY GOD. The semiquavers are followed by demisemiquavers that are entirely [too fast] at this [tempo]. I am a [sad panda]. ❋ Binder Clip (2005)
