My daughter is using a baroque bow hold (holding the stick at the balance point) in order to develop a sense of a good line without the point being dragged towards the floor- this is as suggested by William Pleeth (Jacqueline Du Pre's teacher) in his book "Cello". My question (which is only out of nosiness as her teacher is so great we will do whatever he thinks) - is - how long do you stick with that before moving to hold the bow at the heel?
