Fiddle permits you freedom. If you are GOOD - everyone tunes to you.
If you violin - everyone still tunes to you - (BUT you are ON correct pitch)
Fiddle is easier IF you understand a previous intrument.....you can "tune it" like a "slide guitar" and go for the harmonious-whole.....every sting is in harmony.
If you develope your "EAR" everything is playable no matter the pitch....or the tuning
Unfortunately, if you live by ear-only, you cannot mix with others. A dear friend plays BRILLANT guitar in the sytle of one of the world's greats....unfortunately, his playing must always be solo.
