Harmonic Analysis

Four is a 32-bar AABA standard in Eb major with clean, bebop-friendly harmonic movement. The A section features clear ii-V-I progressions in Eb with some chromatic passing chords (a brief move to Ab major). The bridge moves to a contrasting key center (Eb minor / Db major area) before the final A returns home. At medium-up to fast tempos, Four rewards clean bebop lines and smooth navigation of the ii-V-I cycles. Its manageable harmonic changes make it a good stepping stone from basic changes to more complex bebop.
