§ Ragtime Theory

• John Valerio: Stride and Swing Piano
• Left hand: four beats per measure, alternate bass note and chord.
• right hand: plays melodies at twice the speed of the left.
• Right hand is grouped into additive rhythms : 3+2+3, or 3+3+3.

§ Harmony

• I, IV, V7
• dim7th, secondary dominant
• Joplin used chromatically altered chords.
• Most commonly, a minor triad on top of a IV
• Also, chords built on flat-VI, either as triads or as augmented 6th chords.
• This can be seen as dominant 7th chords build on the flat-VI note of the major scale degree.
