Son filé ad nauseam!
Casorti Op 50 (see link below) no 21 suggests 1 minute per measure.
I suspect he means 1 minute per bow stroke; not 1 minute per bar, which would result in 8 minutes per bow stroke, lol. Or perhaps you disagree? (if you do, I think I'll take up the drums instead, lol)
Yes, if you go back to #19, I think I'm right: -
Gotta do what you gotta do to become an international soloist...
sure Gordon. son filé is one minute per bow. have you seen Nathan Cole's one-minute-bow video?
LOL - yeah, 8 minutes per bow would be pretty insane.... although I remember Josef Gingold suggested aiming to achieve 5 min. per bow. :o
I like the way he says it should be expressionless (in #19).
