This fingering is comparable to that for D4 except for the open register hole. This creates a pressure node (or flow antinode) at the midpoint of the pipe, and thus allows D5 but not D4. Compared with the D4 impedance spectrum, the low frequency minima are less deep, and at considerably higher frequency.
