I so enjoy playing this instrument, the sound is so beautiful, it doesn’t wet out like the other OcariNAF, it has an amazing, deep sound, and it’s just fun. The two holes on the left side are larger, as described but I have normal, female hands and I don’t have trouble covering those holes. They’re very similar to a bass 432Hz flute I have and they are very well-placed so I don’t feel like I have to stretch or play it any differently than other flutes I have. This is now the flute I reach for every day.
