I'm practicing a piece that has a glissando at the very end. It goes from low on the keyboard to the top and the RH has to pop off a little note at the end. When I try doing it with my RH turned over so the backs of my finger tips are on the keys, I get too much clicking sound from my nails. I'm now trying to do it without turning my hand over - using the tips of my fingers with my palm facing down. Is this okay? It feels a little weird. Is there a better way?
