Bow Circles: Good for Tone

          This is one of the simplest ways to build your tone on the violin. It even works with viola, cello, and bass. So what you want to keep in mind:

• the bow needs to be placed gently on the string at the frog (bottom of the bow).
• then pull the bow gently watching that the string resonates (wiggles really fast).
• then circle back to the middle of the bow! 
• keep the bow off the fingerboard and use as much of it as you can.
• start by doing 5 bow circles per string, then every week keep adding 1 more bow circle per string.
• after 2 weeks you can experiment with slower and faster bow circles.
• you can even do bow circles up bow

This warm-up exercise is good for the rest of your life, just like marriage, so keep at it and be creative.
