For the past two posts, we’ve been talking about the altered scale.

Now I want to teach you a trick that will have you playing ANY altered scale you want in 3 seconds… that is, if you know your major scales!

Here’s the ONE and only rule you need to know:

1) Take any major scale and sharp the first and last note. Bam! That’s it!

Yup! I taught you all that other stuff so that you’d understand it… but this is the shortcut I use to play the altered scale!

Of course, it can still be thought of as the ascending melodic minor scale, starting and ending on its seventh note. It can still be thought of as the super locrian mode. All that stuff remains the same.

But what I’m saying is when it’s time to play and you need to think of an altered scale really fast (…because you’re playing some type of dominant chord with a b9 or #9 or b5 or #5… or combination thereof) — this trick will do the job!

But let me make it even plainer for you…

1) If you want to play a particular altered scale, go down a half step. That will be the major scale you’ll need to know…

2) Then basically raise the FIRST and LAST notes of that major scale to get your altered scale. The first and last note will be the same note.

So if I want to play a C altered scale, what do I do?

1) I go down a half step to “B” and determine its major scale.

2) Now I change the “Bs” to “Cs” and I’m ready to go! I’m basically playing a B major scale but replacing the B with C. “B major” just got carjacked! :-)

Here’s the correct way to spell the C altered scale (the notes will essentially sound the same as the ones above… just spelled to take into account the “Db melodic minor” scale, ascending). Remember, that’s the other way you can think of the C altered scale — as the Db melodic scale from “C” to “C.” But to me, this “major scale” shortcut is a lot easier…

C Db Eb Fb Gb Ab Bb C

(I would use my piano graphic here but it doesn’t do Fb yet, darn).

This altered scale will work perfectly over any chord that has the following alterations:

C7 #9#5
C7 b9 #5
C7 b9
C7 #9
C7 #5

These chords are commonly found on 2nd, 3rd and 6th degrees of a scale. They substitute perfectly for minor chords when you need to pull strongly to another minor chord of the scale. I guess you can say they operate as secondary dominant chords… just altered.

I know, I know! Another big one to digest!

Take it slowly and let me know what you think.

Until next time —
