Reharmonize — find jazz standards with similar chord progressions
Type in any of \~3,000 jazz standards (Autumn Leaves, So What, Giant Steps, etc.) and it returns the tunes that share the most harmonic vocabulary, ranked by similarity. Works regardless of key — chord progressions are normalized to Roman numerals first, so a ii-V-I in F matches a ii-V-I in Bb. No signup, no ads. #entertainment
