Uli Jon Roth is a German guitarist who became famous for his work with the hard rock band Scorpions and is one of the earliest contributors to the neoclassical metal genre. He is also the founder of Sky Academy and designer of the Sky Guitar.

In Roth’s early days with Scorpions, his soloing style was based primarily on the blues scale, occasionally incorporating notes from other modes. However, by the time the band recorded the Virgin Killer album, he began incorporating more advanced compositional elements from European classical music: such as pedal tone sequences and intricate arpeggios. Beginning with Electric Sun, the classical influence began to dominate his playing style- notable in songs like “Cast Away Your Chains” and “Still So Many Lives Away”. His style eventually became a fusion of blues-based rock with European classical sensibilities. Roth employs major and minor pentatonic, the blues scale, Phrygian, harmonic minor, diminished, and the whole tone scale.
