What Are Crunchy Quartals? 

The best feeling

As long as your ears are ok.

LoL!

Good idea 👍 I’m gonna work on that,it sounds good !! Thanks 😊

Captain Crunch Quartals for raw Gums.

The other 12 minutes must have been practicing at the keyboard 😂

Well I had to watch it several times and stop it occasionally to make notes. This is now part of my regular practice routines! ❤️

Bravo, maestro...!!!

This is what I consider brilliant educational instruction. He’s always gonna make me work, but with loads of energy, inspiration, and value. That’s Peter Martin. Thanks, brother!

Wow! Now I hear it and understand it! When he said he wasn’t really playing “out” but it sounds like it while sticking to the minor pentatonic I was like 🤯🤯

Same exact experience as you (as a guitar player). I could hear it but had no idea what was happening. This was awesome.

Man, I know the feeling, this kind of stuff is like magic from another realm as a guitar player. We have an advantage that we can bend, trill and slur to taste but the voicing and substitution aspect is a challenge.

But the nice thing is that these chords come so easy to the guitar as tuning of at least the bottom 4 strings are fourths (or well, if you use a standard tuning that is). The regular quartal voicings can be done with just one finger on those strings. When using the D-string as the starting point it's either 2 fingers (incorporating the B-string) or just three (using the E-string). The crunchy derivatives are not difficult either.

Yup, it's great because they are the same voicings as the shell for the #9 chord (a lot of them), and since the #9 is in both that chord and the scale of the tonal center, it makes total sense as a sub. So logical while deriving something still inspired-sounding, creative and hip! Which I think are the cross streets jazz lives at

Like Db-G-C is a rootless Eb7(13) which is a sibling of C7b9, and even that C dominant sound gets along with Cmin/Ebmaj pentatonic, because Eb is a blue note to C.

Just had an ah ha experience. Thanks.

Good observation!!

Good observation! I think that may relate to why he made “crunchies” only on select positions (the 2, 4, 5 and 6 I think it was)

Accounting for the crunch isn't the problem. Accounting for why they should be played with C minor pentatonic IS.

They're also implying the c altered scale (except B which implies c harmonic minor scale)

Thank you, I was wondering why that was what they where playing

It works great on any harmonic instrument.

just another color in the crayon box..

I think you can also try shifting upper notes up... or doing Aug4 + Aug 4. So still with Cmin pentatonic right hand, on the 4 voicing left hand plays F Bnatural Enatural. And that can move chromatically up or down from there all the way down to Db. Then switch the D or second degree voicing to the regular perfect 4th voicing and you can go back to diatonic sound.

Sorry not aug4th + Aug fth. That would be tritone and octave. But the aug4th or tritone + the perfect 4th voicing I think could be played chromatically up and down with the Cmin or any minor pentatonic over that. This a sax player learning a bit of piano though. Another way to riff or to get to the 'out' voicing would be to keep the root and move the upper two notes up a half step. This again stretches the lower half of the voicing creating the tri-tone. So another way to think about it is to add a tri-tone to the voicing by shifting pinky down or top two fingers up. I think the piano player for Cannonball uses this sound chromatically on the live in New York or San Fansisco album. Gemini maybe? So not just McCoy.

Get the transcription, it's fantastic. If you're not a Pro member, I bet they will send it to you if you ask nicely. They're good like that.

My theory of how these alterations come to be is that they are highlighting Gb7 and its chord scale Gb mixolydian. It doesn't matter if you play C or Cb because C would imply Gb lydian scale

I was the same not so long ago. Stick with it, it will come.

Stick to the simpler stuff first. Major scales, minor scales, diminished scales, basic chords…. Then quartals… then crunchy quartals…
