Developing skill in spiccato and ricochet bowing would help immensely. Strong by flexible right-hand fingers and a good bow hold are also essential so that you aren't forcing the bow to bounce as opposed to maintaining the bounce.
It's almost impossible to teach ricochet and spiccato by description alone. It really has to be taught from a practical demonstration, but as a basic outline to achieving it - assuming your bow hold is perfected - place the bow hair on the string, lift the middle two fingers off the bow, press the little finger down to lift (pivot) the bow from the string (without twisting the wrist), then, simply let the bow drop back again - much in the same way a counterbalanced car park gate might work. When done correctly the bow will naturally bounce on and off the string as if it was a rubber ball. If you were to add a quick down bow stroke to this would then be called ricochet because the bounces decrease in size each time. Maintaining a regular bounce for spiccato or staccato comes from the tinniest movement from the little finger.
Common faults include: throwing the bow back onto the string with movement from the wrist or hand. Lifting the bow using the hand rather than it pivoting within the hand by movement from the little finger alone.
Thanks so much Amanda.
I will try that when I practise tonight. I'll let you know how I get on.
