-7 to V7 to Δ Progressions

In Mark Levine's Jazz Piano Book, one of the first exercises is to learn a ii-V-I pattern, with the ii a minor seventh (-7), the V a dominant seventh (7), and the I a major seventh (Δ). In this exercise, you play the root in the bass and the third and the seventh in the treble. (The fifth isn't necessary because it's the third and seventh that determine the quality of the chord.) He says to practice these, going around the circle of fifths, and in both inversions (fifth on top, third on top), until it's all second nature.

So when I was about 28, shortly after I bought the book, I started working on these. They weren't easy. I wasn't very good at music theory (or even reading music) at the time, so it was a real strain on my mind. This was about the time I signed up for jazz piano lessons with a musician in Baton Rouge. At the first lesson, I showed him the little progress I'd made on the progressions, and he suggested that, instead of going around the circle of fifths, I should work make the I of one progression to the ii of the next progression. This way I wasn't having to jump a fourth every time.

So I learned that ... and I wish I hadn't. Because going up a fourth is part of the "second nature" of the exercise. Anyway.

The next chapter talked about suspensions and Phrygian chords and I absolutely did not understand any of it, so I set the book aside, purportedly for a while, and then life circumstances changed and I didn't go back to it for a long time. I still practiced the ii-V-I progressions on occasion, and I even wrote some nice little melodies based on them, but I never got past that Phrygian chapter.

A few days ago, I went back to the Levine book ... and that Phrygian chapter still does not make sense to me. So I moved on to the next chapter, which is much easier to digest. It introduces some color tones into the ii-V-I, and, as with the previous exercise, it says to practice and practice and practice these progressions around the circle of fifths until they become second nature.

Because color tones are added, there are three inversions to learn instead of just two. Here is one of them:


Here is a brief video of me going through these in several different keys, going up a fourth each time.

So ... 12 keys x 3 inversions = 36 progressions that need to become "second nature." I've been working on these for a few days, and, while it hasn't exactly been easy, it's been fun. It's making my brain happy to think on this level.

Once I learn these, there will be inversions with flatted fifths and such ... but it will be a while before I get there.  In the meantime, I'm glad to be back in the Levine book again.

Eureka! Secondary Dominant!

I am such a nerd, and I love being a nerd! Today I was working on Section 5 of You Are My Sunshine, specifically on getting this section up to performance level. In other words, I was practicing being a performer , not an arranger . But then, of course, I came up with another idea. I had just played the delicate sixths and descending rag rolls of "when skies are gray" (I chord) and then moved to the parallel octaves of "you never know, dear" (leading to  IV). The shift sounded abrupt to me. Harsh. It needed something. It needed musical WD-40. Something to ease the hinge between textures. And then I stumbled upon it! Right before moving to IV, I can slip in a V7/IV — a secondary dominant! So I tried it, and it sounded so good that I actually yelled "Secondary dominant!" out loud in my house like I was Archimedes discovering water displacement in the bathtub. It's such a small thing. One little chord. But it smooths that transition, leaning the harmony ...

The Rusty Lock and Key

I'm in a room. There's a door in front of me. On the other side of that door is a whole world of adventure and imagination and joy and delight, but for the moment, I'm locked in this gray little room. The door itself has a lock that is all rusted. I've tried to open it in the past, but I've never gotten very far. Sometimes I try to scrape the rust off the lock. I also have a rusty old key that I occasionally try to polish. Each time, after I've made a little progress, I'll put it into the keyhole in hopes of opening the door. It turns a half a millimeter or so, but the brief excitement at my progress dies quickly when I realize, once again, the lock isn't opening. I set the old key aside, and from there I can forget about the door, the lock, and the world outside, for months—years, even. But then something happens—I hear birdsong, or I catch a glimpse of color—and I pick up the key and start picking away at the stubborn rust. That dark little room is my ...

Ode to Joy Day 3: Patterns, Shapes, and Short Breaks

As I work through Rebecca Bogart's Learn New Repertoire Faster challenge , I'll be posting more extended updates here on my blog. Days 1–3 Day 1 was analysis, listening, and generally scoping out the territory of the music . The road trip to Florida last week turned out to be Day 1, even if I didn't label it that way at the time. Day 2 was fingering and the start of my first "batch": measures 0-7 (intro), 8-15 (Section A), and 16-23 (Section A'). Day 3 (today) was about recognizing patterns and continuing work on Batch 1. Batch 1: Intro, A, A' The intro isn't difficult, and it will likely be one of the two easiest sections in this piece. Still, the syncopation is a little tricky, so I took some extra time with it. I've already memorized it, as the chord progression is pretty straightforward and the melody is just a single line (no harmony notes). There is one big augmented chord at the end that required some focused work. Sections A and A' ar...
