Oh I actually never thought of that before! I'm not really sure about if I vocalize before a performance bc I actually have never heard of that before, but I practice the piece I will perform shortly before a competition or recital starts if I can.
if I'm nervous my hands tend to get cold and tingle. Then my hands start to freeze and become hard to move, especially whenever I'm playing on the piano.
Thank you so much!!! π«Ά
