Creating altered sounds in improvising is a
big deal in jazz. One good scale that does
this is the Harmonic Minor scale. Today's lick
is a classic jazz line for a minor II-V-I
progression in A minor. (Bm7b5-E7-Am7) The
licks begins with a Bm7b5 arpeggio followed by
an Fmaj7 arpeggio outlining the Bm7b5 chord.
The 2nd bar uses the A harmonic minor scale
mixed with a few chromatic passing notes.
Practice this line over Jam track
which is the same progression. Alternate
picking works best for this line. When you
reach the Am7, make up your own ideas using a
C major or G major scale.
