Per title, how does a flutist maintain a grip on the flute when the stops are open?
If the note requires holding down the stops, I would think that grip is between the closed fingers and the thumb, but if all the stops are open (or the note otherwise requires all fingers to be lifted), then how can the flutist maintain a grip on the flute?
(PS to readers in the UK: please don't change my spelling of flutist, I am using the American spelling)
