Greetings fellow listmates. I am new (about 4 months) to arco playing, and recently got a new carbow, German with black hair, and am having trouble getting it to stay "rosined". I've tried both Carlsons and Pop's. With either one, the bow seems to lose it's grip on the strings after only about 10 to 15 minutes. I am located in the four corners area of NM, an area of low humidity and warm temperatures. Any suggetstions or links to previous threads or messages regarding this problem would be appreciated. Thanks in advance, Alex It's really a hoot being in the intermediate summer strings program here at the local community college with junior high students who've been playing a year or so... a contrast between overall life and musical experience and actual arco time and skill.... I'm having a ball!
