Animisha It is interesting, because you'll play with a pounding heart. However, what if you mess up badly in that situation? Would it make matters worse?
I don’t think so. The idea is to experience playing despite the physical reactions.
In my experience, when I’ve had a performance that hasn’t gone well due to nerves and shaking hands, and then had another performance soon after, the second one always goes better. This happened to me last November, when I played in the (mostly kids) recital held by my piano school, and then two weeks later I played at the concert at the retirement center.
These two performances where the first time I’d played in a truly public recital since before the pandemic. And even though I’ve played publicly a lot, I somehow don’t retain the feeling of shaky hands very long, so the first recital, I just couldn’t get control of my shaky hands. For the second one, I think I was just less surprised by the feeling.
So back to your question, @Animisha , I would think that the thing to do would be to do the “pounding heart” practice more than once, not in the same practice session, but a few times over the course of a week. Then if it goes badly the first time, you have a few more chances with it.
