Good evening,
although I read you assiduously, it has been a while since I last intervened on the forum. I am returning to write because I would kindly need some information and advice.
First of all, I would like to purchase Sandor's book "How to Play the Piano". I downloaded the PDF but I would like the hard copy. Unfortunately, it is not available in any bookstore in my city, nor can I find it online. I would appreciate it if someone could provide me with a link to a seller. Thank you.
Now to the point:
Since mid-March, I have started taking piano lessons. Unfortunately, after playing for a while, I begin to experience soreness in my left arm, specifically the forearm, wrist, and part of the back of the hand. The issue was negligible during the period when I was taking lessons (until June), but now that I am practicing at home, the problem has worsened significantly. My teacher told me it could be the stiffness I still manifest in my wrist movements and the fact that I tend to lower my left wrist. I have worked on this latter aspect. As for the stiffness, however, I find it very difficult. To date, I simply cannot avoid keeping my limbs somewhat tense while playing. I still need to work on it when I resume lessons. What doesn't make sense to me, however, is that I don't feel the discomfort at all in my right hand. And I don't understand why. It makes me think that this depends on the movements I have to make with the left hand on the piece I am learning. The teacher told me to make "arched" movements when transitioning from one chord to another and to work a lot "with the wrist" on the second beat of repeated chords.
I have uploaded a video in which I "strum" Chopin (link below):
Apologizing for the mess I make of it, I would really appreciate it if you could point out any incorrect movements/imperfections I make with my left hand so that I can correct them during these months away from lessons.
I have also thought that my discomfort might stem from a cyst I have had on my left wrist for several years (not to be confused with the clearly visible bone, as I am quite thin). This cyst has never caused me any trouble, but I fear that with piano movements it may exert pressure on nerves and tendons, resulting in soreness. I don't know if I should consult a doctor to have it aspirated or surgically removed. The fact remains that this little pain in my left limb gives me pause. I am afraid that by continuing to practice I might worsen the situation, and the idea of having to nip this wonderful adventure I started just a few months ago in the bud distresses me quite a bit. Tomorrow I will upload a video filmed from below, where the movements I make with my left limb are more clearly visible. In this one I have already uploaded, before I start "playing," I show the parts that hurt.
Thank you for any advice you may wish to give me.
