At this point I'll introduce thread creep -- Some time in the past six months there was a thread with a "blue clicky thang" to a web site that had a series of Pentatonic scales laid out for fiddle (and, by default, mandolin). I foolishly forgot to bookmark it, and haven't been able to find it since. It was very well done. Do any of you scaly modeists know where that might be ? I'd be ever so grateful !!!
