Not all fingering charts include the third octave (dai kan) notes, so here they are. Most flutes can play at least up to a dai kan chi no meri (A flat on a 1.8) with no problem. Higher than that is very difficult on some flutes. Practicing these notes at home is a great way to insure that you get the house to yourself.
Go no ha (D on a 1.8) - third octave ro, played with only 5 (thumb) open. On most flutes, head should be lowered a bit.
San no ha (E flat) - third octave tsu no meri. 3 and 5 open, head lowered.
Yon no ha (E) - third octave tsu chu meri. 2, 3, and 5 open. Kari position.
Dai kan tsu (F) - to be in tune on most flutes, play like a tsu meri.
