One aspect of preparation that I am trying to figure out is preparation right before a performance. Currently, my preparation consists of long tones, especially in the low register, five note scales, and then playing the actual piece. And there is the million dollar question; how many times to practice the piece before performing it, and how to play it. How much to practice the day before?? I found a few items online that address this question:
Preparing for Performances and Recitals, written primarily for pianists by Chaun C. Chang.
Should One Practice Very Much the Day of the Concert, by Noa Kageyama, Ph.D., again for pianists, but applicable to all.
Tips for Staying Calm Before A Concert, thread on Stack Exchange.
I’ll be reflecting on these ideas and my own rituals as they develop…. more to follow as I wend my way through these things.
