The tone hole for this note is around 8 inches. For the first few odd harmonics there are antinodes at the start, the mouth piece, and the end, the tone hole. The fifth harmonic strangely ends on an anitnode. All of the even harmonics start and end on nodes. As with F4, special attention should be paid to the shape of the even harmonics. From 2nd-4th, there is one hump, and two humps. The 6th harmonic doesn't show the three expected humps, though.
