The wall experiment
I invite you to engage in a simple experiment and report back with your findings.
Find a wall on the corner of your room with enough empty on your left (entrance or corridor) for your bow when you stand with your back aligned.
Start with your feet and align all the way up.
Practice or warm-up for 10-20 minutes, and pay attention to contact points, especially in the area of your backbone, deltoid muscles and shoulders. Twist the upper part of your body a bit toward your right, come back then toward your left. Detach from other contact points and come back. Bend your knees slightly, stay a minute, then make contact again. Pay attention to your posture, sound production and violin / bow hold.
What was it like? Did you bring awareness in different parts of your body? Did you feel any pain, tension? Was it uncomfortable? Once when you left the wall and came back to your regular posture, did you see any improvement? Any other impressions? Thank you!
My heels were never against the wall and I abandoned after 3 minutes with calf pain. Gorilla don't stand straight.
