Accept my congrats for your 7 years to play the violin.
I have heard that it is a difficult instrument to learn to play it.
Yes, it´s very hard and after 7 years of playing I have many many many things to learn. There is very important your feeling, because, if you don´t feel the melody you can´t play it well and you can´t give the feel into your hand with fiddlestick. Also you haven´t got fret like on a guitar there, so YOU make a sound and every millimeter is important and you have to "have it in your hand" ... but the same is viola, violonceloo ..
