It is essential for a jazz guitarist to understand 2-5-1 chord progressions since they are found in almost every jazz song.  2-5-1, sometimes written as ii-v-i, refers to the chord progression made up from the 2nd, 5th and 1st chords in the major scale.   Minor 2-5-1 uses the chords from the harmonic minor scale.
