The document describes several styles of piano playing including stride piano, New Orleans, boogie woogie, Fats Domino style, Nashville sound, Lennon & McCartney's songwriting style, and Roy Bittan's rock piano style. Stride piano uses alternating bass notes and chords played between hands, New Orleans uses a broken triad bass with rolled chords, and boogie woogie relies on a persistent left hand bass ostinato. Fats Domino style combines a New Orleans bass with even triplet chords. Roy Bittan redefined the piano's role in rock with melodic treble phrases and classical-influenced arpeggios.
