Cheers Tom , I’m not sure if this answers the thumb question , but I’m using the thumb on the keys as I do the fingers.Im trying to start off with good habits , example when I’m practicing scales , I’m trying to use all digits on the right hand in the scale progression rather than moving one finger from key to key.Im trying to practice with the instrument on its side with my left hand directly upright through the handle. My aim is to play the thing without looking at the keyboard.
