At the moment I am not actually having violin lessons, just playing what I want when I want really. I am currently playing "Goodnight Sweetheart" which is an old wartime song, sung by, (I think) Dame Vera lynn.
I am finding is slightly awkward, and someone suggsted playing in 'half position'. What is this?

If you were playing on the D string, half position would be pulling your first finger back for a D sharp, then putting your second finger on E, third finger on F and 4th finger on G. It's often used, especially in viola music, to avoid awkward string crossings.

Hope this helps!

Ahhh. That makes sense now!

Took the words right out of my mouth there Rainbow!

Oh that's just one of my skills... mindreading lol
