When I am learning a song I try to find a way to play a measure using a hand without having to move the hand. I watched a video where some guy was playing the same song as me but he moved the hand even though I would've just stretched my hand to try and make it work. Is his way of doing it better? It seems hard to play it his way, you'd have to move even faster I feel. However, my small hands often can't reach certain chords well.
Basically, how should I place my hands in order to deal with certain songs? I get uncomfortable putting my hands in stretched out positions for too long.
If you think it matters, the song I am talking about is comptine d'un autre été. The left hand part of it which repeats so many times, very rarely is the left hand anything else in the song. It is tough for me to play and yet I am required to play it for like 80% of the piece
