People like David Garret are called virtuosos because they've played since they could walk basically, excelled in all they did, can memorize like 200 classical pieces and never miss a note when they play (or cover it up exceptionally well!) and can play by ear as well.

He's a specific kind of player, born and raised on classical, played in a professional capacity early in his childhood and now is famous for his cross-over playing of modern pieces with the violin.

Picking it up and just playing 'anything' in key, and basically note for note with the current tune, and having a 4 million dollar instrument and actually being able to afford it,,, that would make you a virtuoso in my book.

They play the violin like you and I walk and talk... second nature and although we might trip as we walk, we recover quickly 'naturally' (most of the time). They can speak of most any subject as long as it's about the music. Very few virtuosos can do simple things like change the oil in their car. Re-roof their house. Repair a broken cord on a blender, etc. Their entire life has been devoted to making sounds from a wood box that defy logic and many laws of physics! LOL

I think in many respects FM would qualify as a 'virtuoso' as well. He plays many, many pieces of classical, can play be ear... knows the in's & out's of the world of the classical musician and basically can pick it up and just play... He might compare to others like David as a 'beginning virtuoso' but one never the less.
