"Four" by Miles Davis Major Pentatonic Approach

Plenty of solos exist for this tune. My beginners approach uses only major pentatonic chord scales.

There are only 3 chord scales you need to know to get away with a solo. Bb Major Pentatonic, Ab Major Pentatonic, Db Major Pentatonic.

Those are not the chords, rather they are the chordscales.
The chords are Ebmaj7 Ab7 fmi7 and so on. The major pentatonic chordscale built on the 5th of the chord eliminates the void tones and simplifies the choices. Got it?

There is a moment when a B Major Pentatonic is used, but hell, that's the exact same formation and pattern as the Bb Major Pentatonic, only moved up one fret, so if you can play one then you can play the other.

The Ab and the Db are different stories. Yes, you can shift the whole pattern up or down to the different key but the idea here is to stay in the 6th position through the whole deal.

So, Bb Major Pentatonic is in the 6th position using what amounts to an E scale formation.

Then Ab Major Pentatonic stays in the 6th position but you now use the D scale formation.

The Db Major Pentatonic in the 6th position uses the G formation ( or just pretend you are playing a Bb Minor pentatonic in the 6th position with a G formation.)

Fretboard Logic by Bill Edwards is a good place to start for lessons on placing chord scales along side known chord formations.

Like I said, Bb and B are only a half step difference so you simply move up one half step for that change.

The turnaround (Gm7, F#m7, Fm7, Bb7, Ebmaj7, Fm7 Bb7) is so fast that you have to be playing 16th notes to even establish a chord scale. I stick with my Major Pentatonic through the descending bass (C Maj pent, B Maj pent. Bb Pent....)

The lesson here is staying anchored in the 6th position throughout.
