.Recently I have discovered that alternative fingerings in higher register suite me much more than regular. For eg; for 4th space E standard fingering is all valves open, but I find it easier to play with 1st and 2nd pressed down, just like first line E. Also G above the staff is easier in 1-3 combination than standard all valves open
Is this normal? Can that actually damage my playing? Or should I simply stick whith what suits me the best?
