This fingering is comparable to that for G4 except for the open register hole. This creates a pressure node (or flow antinode) about two thirds of the way along the pipe (one third from the downstream end), and allows D6 but not G4 or G5. (It not only facilitates the 3rd harmonic of G4, it makes the lower harmonics difficult.) Comparing this with the G4 impedance spectrum, we see that the third minimum is little changed. The second is shallower and unplayable. The first minimum plays C5. Both C5 & D6 may be played simultaneously as a multiphonic. For more detail on register holes see the section in the introduction to flute acoustics.
