Thanks for all your supportive replies!
I have heard about the alexander technique, just seen the website, so will go through it taking notes!
I think that the whole posture and wrist movements are so important, and I say this as someone who is really affected by them!
My back hunches sometimes over the piano (I'm sure from years of wearing a backpack with every book going to school - a requirement!) and I suffer really bad tension in my wrists. Because of this, I cant play fast pieces even if I did play it slow simply because my wrist tenses without me realising it! After about a minute, my hands are tired. I honestly thought when I was younger the tension meant my hands weren't "fit" enough, meaning I needed more practice. A vicious cycle!
I do have a teacher, and this teacher spotted the tension immediately. She also spotted that I dont keep my heel on the floor while peddling, she also spotted my raised shoulders, thankfully something thats gone away now! All these bad habits that were never spotted! We work on the tension all the time, but after 7 months its still there, like a bad omen not wanting to go away! I still steer clear of certain pieces, and even though I can play the whole of the moonlight sonata, I will never be able to play it all the way through without my wrists seizing up. I am trying to battle this tension I have but its a struggle!
Knowing all this, you can imagine the fear that set in when the ajudicator at the festival said my student had tension in her body!! "Why didn't I spot it?", "oh my god was it that bad?" I've been thinking about it ever since, and all i can think of is saturday and what exercises we will do to get rid of it!!
Can anyone give me some ideas of what things I should tell her to do while she's playing a piece? I know breathing is one thing, lower shoulders, anything else?
Also how do I tell a student to stop tensing their wrists. My teacher says it all the time, but for the life of me, I still dont honestly know how to do it!!
