Obvious tips would be practising the scalic figures slowly (yes, helpful, eh? ), and maybe in different rhythms (swung, double-dotted, bunches of three), strictly in tempo. So when you go back to doing it in straight quavers, it seems easy by comparison!
I always found that it was difficult to get the top note to ring out cleanly - it ended up, with my initial fingering, on finger 3, which just didn't have the strength to be reliable. So I tried out different fingerings. Ended up with quite an unorthadox fingering, which ended up (I seem to remember) with 1-2-1-2-1-2-2 (for the final note, finger 2 just rolls onto its side, sort of. Hard to explain). Probably not the most pro fingering, but it worked for me, at the level I was playing at!
That's my input, anyway. I'm sure there are far better players who would shudder at such 'solutions'...
Omg i love that song i would listen to it over and over...but i would never play it for a competition...because i knew i would prob be compared to jacqueline dupre. but it so pretty.
Using different rhythmic figures is a great tip. If you continue to struggle w/ it, break down the scale and practice each position change individually. It’s very time consuming, but it will help. good luck!
