The ii-V-I chord progression is so common in jazz (and other music), that it’s worth practicing as a standalone exercise. This will help you learn songs quicker and memorize chord progressions.
A ii-V-I progression consists of three chords – the “2” chord (often written with lowercase Roman Numerals ‘ii’), the “5” (or V) chord, and the “1” chord. In the key of C major, this means D minor 7, G7, C major 7.
