One of our guitarists is a fine luthier and he made a bow for me as a gift. I got it last night, but don't know anything about playing Arco. I have a laundry list of questions.......... How do I determine correct tension on the bow? What type of rosin to apply, how to apply it and how often? What's the proper angle of the bow in relationship to the strings (how much hair should be contacting the strings) Proper way to hold the bow? Correct hand-arm-wrist and body postioning? I know that taking lessons is the answer but I'm financially strapped due to a marriage break up and distance to a teacher is also an issue. I'm self taught, have been playing for about 5 years and work with this semi pro americana-swing band http://www.myspace.com/delvers. Any sage advice from veteran players is greatly appreciated.
