I wanted to write a line this week that used the Harmonic Minor scale over the V7 chord. You'll notice all the notes used over the dominant chord in this week's example come from the Harmonic Minor scale. There are a couple of options to consider when choosing what mode of this scale to use when improvising over dominant chords.
The most common example, first used by be-bop musicians like Charlie Parker and Bud Powell, is to simply use the Harmonic Minor scale based off of the minor i chord relative to the V chord.
G7 - C Harmonic Minor
G7 is the V chord in the key of Cminor. This would be the fifth mode of the Harmonic Minor Scale.
G Ab B C D Eb F or 1 b9 3 4 5 b13 7
I decided to go a different route and use the seventh mode of the Harmonic Minor over our dominant chord.
G7 - Ab Harmonic Minor
G Ab Bb B Db Eb E G or 1 b9 #9 3 b5 #5 13
Remember to sing and play slowly at first. Once you feel comfortable with this line in all 12 keys you can try improvising using the 7th mode of the Harmonic Minor scale on your favorite tunes.
