This can be considered as disturbed version of the E4 fingering, although it is not a simple register hole, as it falls somewhere between half and one third of the way along the effective bore. This far above the filter cutoff frequency, it is difficult to find simple explanations for the resonances. Note that this note operates on the sixth minimum (we are well beyond the harmonic regime in the impedance curve). Compared with that for F6, this minimum is deep and the note is clear and readily played.
