Note that the transcription above is just the last 6 bars of the 12 bar blues in Eb. Gene is mostly using a C blues scale here. (That's the alternative blues scale I taught you last week.)
Playing Double Stops
The note you use on top matters. The most common choices are the root or the 5th of your blues scale, NOT the chord.
If we were playing a blues in G, that gives us 4 primary options:
- G - The root of the G blues scale
- D - The fifth of the G blues scale
- E - The root of the E blues scale (Some call the "G major blues scale")
- B - The fifth of the E blues scale
Over the C blues scale that Gene is playing, he's using the root, C, as the upper note.
The reason it sounds so bluesy is the tension. The flat-3 and sharp-4 rubbing against that fixed note on top is the same friction a horn player creates when they bend into a blue note and hold it. On piano, we have to fake it a bit this way.
3 Things to Practice This Week
- Practice playing your G blues scale over the 12 bar blues changes. Put the root on top of every note as a double stop. Then try it again with D.
- For more color, try the same exercise but using the E blues scale over the G blues changes. Pair the E or B on top as your double stop.
- Try introducing these double stops into your improvisation as accents.
We'll dig into this together, nice and slow, at this Friday's workshop.
