Right I'll start by saying if you want violin virtuosity you can start with some of the Biber Mystery Sonatas and then move on to the Paganini Caprices. In them you'll hear violinists playing just as fast as that unmusical guitar bloke Malmsteen, in fact I remember him having a penchant for playing Bach rather badly.
As for music and scales it's simple. Most Western Art Music is based around the diatonic system which has 8. Your average heavy-metal neanderthal will use the penatatonic scale to make his solo with, and that only has 5 notes in it. Clever cavemen use modes which do have 8 notes in, but harking back to medieval plainchant. The point being the Diatonic scales are harder to use as they have inherent in them a sense of direction, therefore you have to consider there use carefully
