I am learning quite a complicated piece and I have to play consecutive eighth note: Low B to Ab. Anyone got any tips or suggestions about how I could roll the little finger from Low Bb up to the G# on the LH Pad. If I try this I’m hitting a bum note as the finger catches either Low B or Low C# and I can hear it. Would it be best to lift my little finger from Low Bb to Ab? I’ve tried this but it’s too slow. Practice perhaps?
