Inversions are one of the fundamental fountains of knowledge when it comes to learning harmony. They increase your fretboard awareness, spice up your chord knowledge, and impress all your friends who are stuck trying to get their barre chords sounding great.
Except for sight reading, inversions have been the skill that breaks the most students in terms of frustration. However, they have also led to the "eureka" moments in their studies when the neck just opens up for them. Over the years I've adopted this system on mastering your inversions by learning the shapes and applying them to songs.
The Basics of a Drop 2 Chord
There are two main families of 7th chords: drop 2 and drop 3. With these two families you have access to a vast majority of the chords used by greats like Wes Montgomery or Joe Pass. The voicings are very versatile and will open up the entire geography of the fretboard. For our purposes, we will focus on drop 2, but the concept can also apply to drop 3.
Drop 2 chords cover the most range of the instrument without creating dissonances and provide a massive number of options. How one arrives at a drop 2 chord sounds mysterious, like a strange code. However, it's not that difficult. Let's start with a basic Cmaj7 chord in root position (C–E–G–B). Next, we take the second note from the top, which would be G, and drop it down an octave to create a new shape (Ex. 1).
Ex. 1
The new shape (G–C–E–B) is 2nd inversion Cmaj7 chord and likely doesn't look that unfamiliar. It's more open, stable, functional, and playable in any situation that a Cmaj7 chord could be played. Simple, right?
Next, we will want to extend this idea to the remaining inversions along the neck. In Ex. 2 I've written out the four drop 2 shapes for Cmaj7 along the top four strings.
Ex. 2
I use the term 1573 for a specific reason. This is a way to memorize and visualize the voicing on a deeper level so that you know the function of each voice rather than just internalizing a grip that you spew out. It allows you to alter your voicings to suit your personal tastes in terms of harmonic extension and character. Here are the formulas that correspond with each inversion of a Cmaj7 chord.
1573 C–G–B–E Root position
3715 E–B–C–G 1st inversion
5137 G–C–E–B 2nd inversion
7351 B–E–G–C 3rd inversion
Because of the nature of the drop 2 voicings, we are now offered a large library of new shapes. These exist on four adjacent strings. That gives us three different groups of voicings to learn: one based with the lowest note of the voicing on the 6th string, one on the 5th and one on the 4th. They all have different uses, but that is something we don't need to worry about just yet, we need to get these shapes in your hands and ears.
I've outlined the set of major 7 chords with the lowest note on the 4th string (Ex. 2). In Ex. 3 you can see the shapes based on the 6th string and Ex. 4 covers the 5th string.
Ex. 3
Ex. 4
Mastering all three groups of voicings gets you ready to play in real musical situations. Listening to the solo arrangements of players like Joe Pass and Wes Montgomery, you will discover much of their chord vocabulary is based off this group of voicings.
Now We Exercise
Memorizing the shapes of the chords is the first step to practical application. With four variations on each 1573 chord there is a lot of work to get to. One of the most practical ways is using these shapes to harmonize a major scale. Keeping everything diatonic (within a key) we end up with the following harmony:
Imaj7–IIm7–IIIm7–IVmaj7–V7–VIm7–VIIm7(b5)
Translate that to a key of your choice. Let's start with the key of F, which is a very common key in jazz repertoire, and covers a good range of the instrument.
We begin with the lowest possible root-position chord voicing on the top four strings, which in this key would be Em7b5 (Ex. 5). Naturally, we would move up the neck with each note going to the next scale tone.
Ex. 5
As with every exercise we want to transpose this into other keys. Once you can play this in F major, go to the next key and apply the same concepts. After you get a grasp on your root position chords, start applying inverted shapes right away (Ex. 6). In this exercise, we are working on 1st inversion chords starting with a C7 with an E in the bass.
Ex. 6
Continue this until you can get through all inversions in every key on each of the three string sets. Although these three exercises aren't expansive, they will give you plenty of material to practice. Remember, when you start to learn any new chord shape it takes a little time, but eventually it gets easier.
Playing these shapes across the string sets really opens things up. In Ex. 7 I apply these shapes across all three string sets.
Ex. 7
Now you could not play this entire passage on just the lowest string set, however you need to switch string groupings as you continue to progress. The choice as to when you change groups is yours, and you will want to be able to make this "swap" at any point in the progression instinctively.
In Ex. 8 I've given you one possible way to navigate through all four inversions across all three sting sets. This exercise is very useful in getting a strong start on the basic major scale shapes. Don't rush these; nothing will be internalized and memorized overnight. Remember, we have to not only learn the physical shape of the chords but get comfortable with the sounds that they create.
Ex. 8
Our next exercise will help visualize how each inversion works together going down the neck. In Ex. 9 we start with a higher voicing of Cmaj7 (in 10th position) and work our way down diatonically by keeping all common tones the same. For example, both Cmaj7 and Dm7 share a C, so that note stays while the upper notes move to the closest chord tones. We continue the pattern down the neck and across to the lower string sets.
Ex. 9
Take this process and apply it to all 12 keys to reinforce all of the inversions. Remember, you will be switching string groupings throughout this exercise, so find the best option for you.
Progressions
Practicing these basic exercises helps to get familiar with the shapes, but as you practice them you're going to want to use them over common progressions. Jazz standards move keys often, and in ways that are formulaic and predictable. I teach my students to learn these very common chord progressions in inversions as part of an etude. That way, they learn their inversions not only as a shape, but how they actually work in a tune.
The most common progression is the IIm7–V7– Imaj7. It's also the fundamental basic way of mastering inversions outside of just getting your fingers to make the shape. In Ex. 10 I've gone through a few examples in the key of G. Several of these will stretch out your fingers but after some diligent practice they will become more comfortable.
Ex. 10
Now, you have progressed through learning the basic shapes of the Drop 2 or the 1573 chords, let's unlock the last subject of this lesson, how to play them in song form. As I had mentioned earlier, standards seldom stay in a key for very long. There always seems to be a key change at the bridge, or even several key changes throughout a chorus. Here are a few really common shifts that happen in jazz tunes just to get the ball rolling. Learn these relationships, transpose them, and you're going to be way ahead of the curve.
Practice these studies with a metronome, go slowly, and internalize them. It may take a while for you to get everything nice and smooth. It's a long journey to really get some of this under your fingers and into your ears.
In Ex. 11 we start in the key of G and then play a progression in E minor, which is the relative minor of G. Break open your Real Book to nearly any page and you're likely to find this one.
Ex. 11
For Ex. 12, we start in F major before shifting to Bb major. This I–IV motion appears in countless tunes. Notice how moving across the string sets opens your ears to the relationship between the bass note and the melody. Many times those are the key notes when picking up chords by ear off a recording.
Ex. 12
Moving around by whole steps is another tried and true harmonic pattern. By now, I'm sure you're starting to recognize sounds and inversions and how they interact. In Ex. 13 I've written out a handful of ways to play through a IIm7–V7–Imaj7 in Bb and then move down a whole step to Ab.
Ex. 13
Finally, we get more adventurous with Ex. 14. Here we move from the tonic, in this case Eb, to a minor progression in the key of G, the 3 of the scale. Sounds like jazz to me, right?
Ex. 14
I get it. That's a lot of information. This is going to keep you busy for a while. But remember, you don't have to use all of these voicings. Find the ones you like, pick a tune, and get to work.

John Doe and Billy Zoom keeps things spare and powerful, with two basses and a single guitar–and 47 years of shared musical history–between them, as founding members of this historic American band.
There are plenty of mighty American rock bands, but relatively few have had as profound an impact on the international musical landscape as X. Along with other select members of punk’s original Class of 1977, including Patti Smith, Richard Hell, and Talking Heads, the Los Angeles-based outfit proved that rock ’n’ roll could be stripped to its bones and still be as literate and allusive as the best work of the songwriters who emerged during the previous decade and were swept up in the corporate-rock tidal wave that punk rebelled against. X’s first three albums–Los Angles, Wild Gift, and Under the Big Black Sun-were a beautiful and provocative foundation, and rocked like Mt. Rushmore.
Last year, X released a new album, Smoke & Fiction, and, after declaring it would be their last, embarked on what was billed as a goodbye tour, seemingly putting a bow on 47 years of their creative journey. But when PG caught up with X at Memphis’s Minglewood Hall in late fall, vocalist and bassist John Doe let us in on a secret: They are going to continue playing select dates and the occasional mini-tour, and will be part of the Sick New World festival in Las Vegas in April 12.
Not-so-secret is that they still rock like Mt. Rushmore, and that the work of all four of the founders–bassist, singer, and songwriter Doe, vocalist and songwriter Exene Cervenka, guitarist Billy Zoom, and drummer D.J. Bonebreak–remains inspired.
Onstage at Minglewood Hall, Doe talked a bit about his lead role in the film-festival-award-winning 2022 remake of the film noir classic D.O.A. But most important, he and Zoom let us in on their minimalist sonic secrets.Brought to you by D’Addario.
Gretsch A Sketch
Since X’s earliest days, Billy Zoom has played Gretsches. In the beginning, it was a Silver Jet, but in recent years he’s preferred the hollowbody G6122T-59 Vintage Select Chet Atkins Country Gentleman. This example roars a little more thanks to the Kent Armstrong P-90 in the neck and a Seymour Duncan DeArmond-style pickup in the bridge. Zoom, who is an electronics wiz, also did some custom wiring and has locking tuners on the guitar.
More DeArmond
Zoom’s sole effect is this vintage DeArmond 602 volume pedal. It helps him reign in the feedback that occasionally comes soaring in, since he stations himself right in front of his amp during shows.
It's a Zoom!
Zoom’s experience with electronics began as a kid, when he began building items from the famed Heath Kit series and made his own CB radio. And since he’s a guitarist, building amps seemed inevitable. This 1x12 was crafted at the request of G&L Guitars, but never came to market. It is switchable between 10 and 30 watts and sports a single Celestion Vintage 30.
Tube Time!
The tube array includes two EL84, 12AX7s in the preamp stage, and a single 12AT7. The rightmost input is for a reverb/tremolo footswitch.
Set the Controls for the Heart of the Big Black Sun
Besides 3-band EQ, reverb, and tremolo, Zoom’s custom wiring allows for a mid-boost that pumps up to 14 dB. Not content with 11, it starts there and goes to 20.
Baby Blue
This amp is also a Zoom creation, with just a tone and volume control (the latter with a low boost). It also relies on 12AX7s and EL84s.
Big Bottom
Here is John Doe’s rig in full: Ampeg and Fender basses, with his simple stack between them. The red head atop his cabs is a rare bird: an Amber Light Walter Woods from the 1970s. These amps are legendary among bass players for their full tone, and especially good for upright bass and eccentric instruments like Doe’s scroll-head Ampeg. “I think they were the first small, solid-state bass amps ever,” Doe offers. They have channels designated for electric and upright basses (Doe says he uses the upright channel, for a mid-dier tone), plus volume, treble, bass, and master volume controls. One of the switches puts the signal out of phase, but he’s not sure what the others do. Then, there’s a Genzler cab with two 12" speakers and four horns, and an Ampeg 4x10.
Scared Scroll
Here’s the headstock of that Ampeg scroll bass, an artifact of the ’60s with a microphone pickup. Doe seems to have a bit of a love/hate relationship with this instrument, which has open tuners and through-body f-style holes on its right and left sides. “The interesting thing,” he says, “is that you cannot have any treble on the pickup. If you do, it sounds like shit. With a pick, you can sort of get away with it.” So he mostly rolls off all the treble to shake the earth.
Jazz Bass II
This is the second Fender Jazz Bass that Doe has owned. He bought his first from a friend in Baltimore for $150, and used it to write and record most of X’s early albums. That one no longer leaves home. But this touring instrument came from the Guitar Castle in Salem, Oregon, and was painted to recreate the vintage vibe of Doe’s historic bass.

Hometown: Myrtle Beach, South Carolina
Guitar: The Green Snake
Reader T. Moody turned this Yamaha Pacifica body into a reptilian rocker.
With a few clicks on Reverb, a reptile-inspired shred machine was born.
With this guitar, I wanted to create a shadowbox-type vibe by adding something you could see inside. I have always loved the Yamaha Pacifica guitars because of the open pickup cavity and the light weight, so I purchased this body off Reverb (I think I am addicted to that website). I also wanted a color that was vivid and bold. The seller had already painted it neon yellow, so when I read in the description, “You can see this body from space,” I immediately clicked the Buy It Now button. I also purchased the neck and pickups off of Reverb.
I have always loved the reverse headstock, simply because nothing says 1987 (the best year in the history of the world) like a reverse headstock. The pickups are both Seymour Duncan—an SH-1N in the neck position and TB-4 in the bridge, both in a very cool lime green color. Right when these pickups got listed, the Buy It Now button once again lit up like the Fourth of July. I am a loyal disciple of Sperzel locking tuners and think Bob Sperzel was a pure genius, so I knew those were going on this project even before I started on it. I also knew that I wanted a Vega-Trem; those units are absolutely amazing.
When the body arrived, I thought it would be cool to do some kind of burst around the yellow so I went with a neon green. It turned out better than I imagined. Next up was the shaping and cutting of the pickguard. I had this crocodile-type, faux-leather material that I glued on the pickguard and then shaped to my liking. I wanted just a single volume control and no tone knob, because, like King Edward (Van Halen) once said, “Your volume is your tone.”
T. Moody
I then shaped and glued the faux-leather material in the cavity. The tuning knobs, volume knob, pickguard, screws, and selector switch were also painted in the lemon-lime paint scheme. I put everything together, installed the pickups, strung it up, set it up, plugged it in, and I was blown away. I think this is the best-playing and -sounding guitar I have ever tried.
The only thing missing was the center piece and strap. The latter was easy because DiMarzio makes their ClipLock in neon green. The center piece was more difficult because originally, I was thinking that some kind of gator-style decoration would be cool. In the end, I went with a green snake, because crocodiles ain’t too flexible—and they’re way too big to fit in a pickup cavity!
The Green Snake’s back is just as striking as the front.
This hollowbody has been with Jack since the '90s purring and howling onstage for hundreds of shows.
Our columnist’s Greco 912, now out of his hands, but fondly remembered.
A flea-market find gave our Wizard of Odd years of squealing, garage-rock bliss in his university days.
Recently, I was touring college campuses with my daughter because she’s about to take the next step in her journey. Looking back, I’ve been writing this column for close to 10 years! When I started, my kids were both small, and now they’re all in high school, with my oldest about to move out. I’m pretty sure she’s going to choose the same university that I attended, which is really funny because she’s so much like me that the decision would be totally on point.
The campus looks way nicer than it did back in the ’90s, but there are similarities, like bars, shops, and record stores. Man, our visit took me back to when I was there, which was the last time I was active in bands. Many crash-and-burn groups came and went, and it was then that I started to collect cheap guitars, mainly because it was all I could afford at the time, and there were a lot of guitars to find.
In that era, I was using an old Harmony H420 amp (made by Valco), a Univox Super Fuzz, and whatever guitar I was digging at the time. I was so proud to pull out oddball guitars during shows and just have this totally trashy sound. Squealing and squeaking and noisy as heck, my style was reminiscent of Davie Allan, Ron Asheton, and Chuck Berry. Of course, I was way worse than all of them, but I did have a frenetic energy and I covered up my lack of skill with feedback. During the ’90s, there was a great punk revival, and I loved bands like the Mummies, Teengenerate, the Makers, the New Bomb Turks, and a bunch of others. Bands were embracing lo-fi, and I was planted firmly in that vein. Plus, the guitars I liked to use already sounded lo-fi.
“This was about the trashiest-sounding guitar, but in a good way!”
For a short spell I was using this Greco guitar and, man, this was about the trashiest-sounding guitar, but in a good way! See, Fujigen pickups (like the ones here) have this echoey voice that I describe as an “empty beer can” sound. My Super Fuzz would just destroy these pickups, and I wish I had some recordings from that era, because it was a real scene! I believe this Greco was a flea-market find but it was much later that I found out it was called a Greco Model 912. This was actually a copy of a German-made Framus guitar, but with a lot more glitz and a crazier headstock. Four pickup selector switches, volume/tone knobs, and a rhythm/lead switch rounded out the electronics. Again, these pickups are instant spaghetti-Western movie tone. Airy and bright, the bridge area is like instant, gnarly surf music. Tom Morello of Rage Against the Machine has a similar guitar and John Barrett of Bass Drum of Death was also fond of these pickups. Interestingly enough, these particular Grecos were made in small numbers, ranging between 500 to 600 in total (including all pickup combinations).
The Greco brand was initially owned by the U.S.-based Goya Corporation, but in the late 1960s, Fujigen bought the brand name (for $1,000) and produced a few truly gonzo guitars, including this Model 912. Originally called the GE-4, the four-pickup version sold for $99.50 in 1967. My particular 912 was sold at Sid Kleiner Guitar Studios in Califon, New Jersey (which I learned thanks to the attached store sticker on the headstock).
Aside from the chrome coolness and the four pickups, this model featured a cute little flip-up bridge mute that was all the rage at the time. The body also had some tasteful German carvings around the edges, and as I write this, I am missing this guitar tremendously! But not even close to the way I’m going to miss my girl in a few months. At least I know that she can shop at the same record stores!
