Please guys I need someone to show me how to play the C major scale on a fretted violin (diagrams would be helpful). Also does one play on the frets or in the spaces between the frets. Thanks guys.
Perhaps you want to look at mandolin fingering charts, since they're tuned the same and actually have frets. If you have imaginary frets on your violin, something that's not a physical fret, you would want to finger at those points. On an actual fretted instrument you press just behind the frets. The other musical thing is to listen to what you are doing, and trust your ears, assuming you know what a major scale is .
I'm curious what's so special about playing just a C major scale.
I recommend you take a look at the fiddle fretter. You place your fingers as you would for an unfretted fiddled. I put it on my lower priced fiddle for learning 3rd position.Worked like a charm. Good Luck.
I think that you could easily learn the key of C by learning the intervals between the notes... if you can play in the the key of G, then moving the patterns down one string will give you the key of C...once you have it, then you can move the fingering to the upper strings etc...
Cyndy is right that C is probably not the easiest place to start, but if that's what you want, why not try it? Your questions were mostly answered in the first reply from Brian. If you Google "mandolin scales" you should find everything you need.
One thing Cyndy didn't mention is that if you learn her fingering suggestions, and then move over one string and start on the open A string you'll end up with an A scale, using the exact same fingering. And if you move down one string and use the same fingering starting on the open G string you have a G scale. So three of the most common fiddle scales are available with just one pattern of three fingers. Lots of musical possibilities there.
