BOW HOLD AND PRESSURE.
I personally have struggled with these, to have a lose but firm grip with a flexible wrist, I have tried several ways of holding the bow to have that and still maintain control it still a work in progerss to get it the best it can be.
Being as I have always used my hands and arms to grab and hang onto equipment along with moving heavy items, that you did not want to get loose. Having a light touch especially at the frog is difficult at best for me, I tend to have a very heavy hand when bowing and when playing higher up the finger board I crush the sound all the time having to much pressure. For me it a field of study that I'm personally have a hard time mastering to my satisfaction.
Master the Frog and you have mastered the bow.
Don't worry, Mark. You may find that overly light bowing is the more common problem, and its a bullet you have dodged! I notice my bowing growing too light, and assume it's fatigue, but my teacher says, no, it's because my brain is working too much on my left hand and losing control of my right hand.
So maybe you should try finding something more demanding for your left hand?
Either that, or your right hand is moving too slowly for the pressure you are applying.
Try some long fast bold bow strokes.
(sorry, CID, but I'm not sure I understand the thread's remit)
Two comments about bowing, one, I’ve found it to be more challenging than intonation in some of the songs we are playing for our Christmas program. Also, throw in a challenging rhythm and accidentals and believe me, your head is spinning. There is so much to playing a violin that people don’t comprehend. Two, recently my wife made a video of a song I’m playing and I didn’t have a clue I was pulling the bow toward me as I was playing a long bow. I’ve found I must consciously juke the front of my shoulder out as I extend the bow to keep it straight. That has become part of my daily practice routine now. Just my 2 cents worth on the subject of bowing. Have a great Friday everyone!
