Just thought I'd share this fun, medium swing jazz practice backing track made for improvising on the essential and classic minor 2-5-1 progression

It's in the key of A Minor.

Chord progression:

II: Bmin7b5 I E7 I Amin7 I Amin7 :II

On the track, you will hear extensions of these chords - as is common in jazz of course

Scale suggestions:

A minor scale - A B C D E F G (A)

(Bmin7b5 chords and Amin7 chords)

A harmonic minor scale - A B C D E F G# (A)

(E7 chords)

Basic arpeggios:

Bmin7b5 arpeggio = B D F A

E7 arpeggio = E G# B D

Am7 arpeggio = A C E G

Next up, try out some more advanced colours on the dominant chord (E7) by treating it as an altered chord and using the altered scale:

E altered scale - E F G Ab Bb C D (E)

The altered scale is the mode which starts on the 7th step of the melodic minor scale, so in other words - the notes of E altered scale are the same as those of F melodic minor scale
