Finger independence routine as a composition tool

Hand independence is one of those technical things that I unconsciously put off for as long as I can, trying to justify it by telling myself that it’s not as important and that I’d be better off focusing on theory or learning pieces, plus it’s just plain boring and frustrating, so why start it anyway. And it’s all right until I sit down to record another piece and realise that I need 20 exhausting takes to lay down a fairly simple part because I just can’t reconcile left hand bass pattern with the melody that my right hand plays. Furthermore, because of the lack of focused work on independence, my fingers tend to avoid complex patterns and I often end up with similarly sounding, repeating melodic landscapes. So yeah, dedicated hand independence workout is important because it improves composition.

But instead of reaching for a Czerny book and embarking on a 10-year nightmare of finger exercises, I decided to make use of some jazz voicings and — as always — come up with a routine that would be fun and musical. So I could actually compose stuff in the process.

Here’s what I started with:

As you can see, the right hand simply plays notes from the shell voicing of a major 7th chord (7-3-5 in this case), while the left hand walks up and down the major 7th arpeggio (in full 1-3-5-7 form). Just breaking a shell chord voicing into individual tones already creates a pleasant-sounding line! What is the obvious next step to sex it up?

Yes:

Add broken 10ths in the left hand. Alternating 10-5-1-5-10 pattern and walking ∆7 arpeggios with LH against the same line with RH already sounds super jazzy and very rich. Just in case — I’m going around the cycle of 4ths here (C∆ → F∆ → etc.) and playing corresponding 7-3-5 shells with my right hand.

Next step — try a more sophisticated intervallic pattern. I love 6ths, James Jamerson loves 6ths, why not take them?

First, isolate them and practice over descending and ascending arpeggio to let the right hand get used to the new pattern, and then — combine all left hand and right hand lines in one workout:

Here C∆ 7-3-5 figure is played over broken 10ths, and then in the next bar, the 6-5-3-7 pattern in F major is played over F∆ arpeggio. Obviously, you can continue on and go around the cycle of 4ths / circle of 5ths or a modal II—V—I.

Finally, here’s an example of a real world application of the all aforementioned techniques. I took the first couple of bars of Always on My Mind by Brenda Lee (D | A | B- | D) and just improvised on them playing mostly 1-5-10, 1-5-1′ pattern with the left hand and different intervallic patterns with the right (mostly focusing on melodically played 7-3-5 shell). Check it out, I’m using colours now! Does it make notes on the staff look less (more?) annoying? 🤓

Reversed stride bass in the context of satisfaction

Okay, first post after a two-week vacation! The best advice I could give to my two-week-younger self? Don’t ever take a goddam break from posting! I should’ve known this trap already, and yet I fell into it just like that. Anyway, on the plus side, I have tons of new sheet music and practice routine ideas waiting in the pipeline now, so expect high activity in the nearest future 👌🏻

Alright, today I wanted to talk about another left hand pattern that is worth exploring after you’ve mastered the broken 10ths and the excitement of mixing them with other diatonic intervallic patterns has started to wane. Reversed stride bass! I found it in the wonderful book Jazz Piano: The Left Hand by Roberto Scivales (which I highly recommend to everyone), got blown away by it and then amended it in order to use it in my own routine.

Reversed stride bass is — well, stride bass played backwards 🤓 Instead of hitting the root in the low register and then following up with a block triad or shell octave or two above, you do the exact opposite. Here’s the exercise that I used to practice this movement:

Screenshot 2019-04-28 at 5.35.25 PM

The right hand here plays rootless voicings with minimal movement voice-leading pattern (7-3-5 → 3-7-9) around the cycle of 4ths. The left hand plays chord shells one octave lower and roots two octaves lower. You may also add root — 5th — root octave up movement to complement the rhythmic figure, but it’s more of an ornament.

You can absolutely play block chords in place of shells with the left hand, but, to my taste, doubling roots just sound too muddy. As always, after cycling that thing, take it to your favourite modal progressions & songs.

Reverse stride may sound a bit weird on its own, so, in order to add some FAT and intensity, you can actually combine it with broken 10ths (1-5-10) and block triads! It might be a bit tricky to get used to, but super fun to practice. Check this out:

Same routine (cycling → modal DNAs → songs).

Just for the hell of it, here’s the (slightly oddly voiced) ii—V—I—IV improv that makes extensive use of the above pattern:

I’m definitely not done practicing it yet, so it most likely is going to be one of my priorities in the next sessions. There aren’t too many things as satisfying as hitting the low A after a rather watery sounding 7th chord shell played over another shell, both of which are trying their best to avoid the root 😄 Till later—

How to deal with mad accidentals in harmonic minor modes

Harmonic minor is a bitch. Well, what I wanted to say is that it’s tricky in terms of getting fluent in it and not messing it up when you improvise. That raised 7th degree is super dissonant, it almost gives a feeling of a “wrong note” in a lot of contexts, so in order to get it properly wrong, you need to make sure your fingers remember what it is. The problem with accidentals in Hm is that the standard formulas for flats and sharps do not work, and “4 flats” does not automatically mean “Bb, Eb, Ab, Db”, as it would in any major mode. So you really need to get quick at figuring out what the 7th is and then raising it half step — or just get comfortable with all the accidentals in each key. Sounds like a lot of boring math, but I actually came up with a fun exercise that makes it sound super fancy and can turn your next practice session into a — you guessed it — extremely entertaining pastime.

The idea is simple: one of your hands only plays scale degrees with accidentals, the other one only plays naturals — in any octave, in any combination, harmonically or melodically. That’s it! You do it for one measure, and then you change hands. If the left was playing only altered degrees, it has to switch to naturals, the right then will switch to accidentals. For the next measure, you change the key (like, go around the cycle of 4ths maybe?). Here’s an example of Bb harmonic minor going into F harmonic minor going into Eb harmonic minor:

And here’s how it sounds:

It might start sounding a bit like shit once you get to the keys with a lot of accidentals (like Eb here), but in this case, you can just turn off the restrictions and use all notes in both hands.

Oh, and yes — try in any major mode or blues scale to experience the instant gratification of not having to think about the raised 7th 😆

Practice session: harmonic minor and rootless broken 10ths

Scale studies

All Hm1 scales

Left hand

Broken 10ths recap: Dorian DNA (i7 — IV) in all keys
Descending motion focus: rootless broken 10ths
Having some classical time: all minor 7th arpeggios in descending motion

What do I mean by “rootless broken 10ths”? 🥴

These are normal broken 10ths with some diatonic line (going from Cm to Fm):

Here, I’ve just replaced 1s (C) with the 9ths (D) to get a super sexy sound of a 9th played below. Give it a try (and ignore the second measure):

Becoming a scale monster

Last week I’ve shared a non-boring scale hack that is supposed to turn the scale studies that are often viewed as boring and mechanical into an — quoting Dan Haerle — extremely entertaining pastime. I am using it all the time, and just recently I’ve come up with a new workout that could be viewed as a sequel to the original one. Word of warning: its efficiency in terms of fucking up your brain and your finger muscles has improved exponentially. This is why I called it The Scale Monster.

At some point in my bass training I have been introduced to the concept of chord permutations. Basically, it’s just pure math: you have a 7th chord arpeggio, and there are 24 ways to play these notes in a sequence. Not a big deal, right? Later, you realise that you can then take all inversions of this chord and permutate them. Which will give you 96 sequences. Which you will then transpose to all keys and circle around all the modes and create all the Western music.

Of course, it would be crazy for a human to just mechanically practice this hell (although it does improve your fluency tremendously). Instead, you can just use it as a pool of pre-generated patterns to sex up your routine!

Check it out — this is just a regular F#m7 chord played consequently in all inversions:

Screenshot 2019-04-03 at 20.08.34.png

Easy, right?

Going on — F#m7 in all permutations starting on 1:

Screenshot 2019-04-03 at 20.15.51.png

Personally, I just like how it sounds. There is no trace of that worn-out minor arpeggio sound that so many other people are practicing at this very moment all around the world. Yes, it’s a bit robotic — but — we’ll fix that in a sec.

Next — my “aha!” moment: 1st inversion in different permutations:

Screenshot 2019-04-03 at 20.21.48.png

Note that permutating the inversion does not give you the same results as permutating the original chord, as the root (aka 1) is transposed one octave above. So it’s a completely different set of combinations.

As a next step, I’m going to take one permutation of choice (1-3-5-7 in this case) and play all inversions of my F#m7 using it — ascending, then descending:

Screenshot 2019-04-03 at 20.32.29.png

And finally, add the right hand that is going to play the F# Dorian scale dissected into groups of 2 notes:

Screenshot 2019-04-03 at 20.42.13.png

If up until this point you were only mildly challenging the part of your brain responsible for scale fluency, now’s the moment when you finger independence gets fucked up big time! 🤓

Not all of it might sound great — as particular permutations might create dissonant intervals with scale degrees, but that only means that you can spend another two hours trying out other ones figuring out the best combination. And — remember — it was only F# Dorian over F#m7. Sooo… You get the idea 🤙🏻 Harmonise ’till it hurts! Till next time—
