For the record...

I originaly mentioned the 'natural' interval scale, and then waffled towards a term I 'just' didn't really understand... sorry... I am very consistant when I am 'free' tuning to a drone note... and the scale that I come up with 'doesn't play well with others', but it sounds 'right' to my ear. The resolve of the dominant chords pertaining to the tonic drone are very satisfying, and soothing. Although the effect is considered minimal, to my ear, it is consistantly preferred. If I am playing fixed tone tempered instruments, this question never comes up... and this thread is helping me get to the marrow on this nagging issue for me... Thanks so much!

Come to think of it, this may be why the fiddle is so difficult for me... Cheerio! ttr
