Excerpt from an Yngwie interview:
One year later my older sister Lulu gave me DEEP PURPLE’s Fireball, which is a really hard rock album, and I went out and bought In Rock the next day. I was listening to songs like 'Fireball', 'Flight Of The Rat' - just so heavy - so I learned how to play all these solos and stuff and, contrary to most people’s opinion or theory, is that Deep Purple, along with all other rock ‘n’ roll bands were all blues based. Pentatonic scales and my classical influence did not come from them. A lot of people seem to think so, but no no no no.
I love these guys… my favourite band ever. My classical music didn’t come from there, but my love for hard rock was definitely from ’Purple. What I wanted to do was try and take this whole thing with the double bass drums and the Marshalls all the way up and all that shit, and play with counterpoints and pedal notes, inverted chords, Phrygian modes, inverted scales, diminished scales… all that shit.
Then I saw a TV program: it was a guy playing violin. They said it was music from Niccolo Paganini. When I heard that I said ‘fuck, that’s what I want to go for on the guitar’. So my guitar playing is 99.9 per cent influenced by classical violin… mainly Paganini, Vivaldi, and Tchaikovsky… and my songwriting is very Bach in the structuring, because I’ve always loved the counterpoint and the harmonic minor kind of things… but I love the sound of the metal ensemble. That’s how it all started."
