This is the fastest I've ever played (with little to no tension). I started out about 2 hours ago at 60 bpm, focusing on every subtle motion, and playing as efficiently and clean as possible. I slowly moved it up to now (without stopping), at 140 bpm. I tried 150 and 160, but I'm not quite ready for that yet.
My wrist does feel kind of tired, but it didn't hurt while playing. I might be overthinking, but Papa Gates said that you should be able to play at high speeds for a long time without feeling tired. So am I playing wrong, or is it natural to feel fatigue after 2 hours of playing?
If there is anything wrong with my technique, please let me know. I really don't want any bad habits. Thank you so much for watching!
