Bass players have a significant role in controlling how harmony is perceived, so brush up on those fundamentals.
Following our “Walking Bass Crash Course,” I thought it would be useful to begin a companion piece on harmony for bassists. Harmony is a massive subject, so this will be one of a few. As I’ve told many students over the years, us bassists must exist between the worlds of rhythm, harmony, and melody. A true understanding will help you realize that these are really all the same thing, and the great master bassists of the past understood this.
Harmony is when individual things are in agreement. In ancient Greek, “harmonia” meant “agreement, concord of sounds,” or the optimal joining of things. Those things could be a group of people, planks of wood to make a ship, or nations of the world who get along. We’ll focus on tones in harmony. Take A, C, and E for example. It may seem obvious that these tones spell an A minor chord. However, long ago, before the science of harmony was well established, this was not so obvious.
There are two basic states within harmony: dissonance and consonance. Consonant sounds complement/reinforce each other, while dissonant sounds fight each other, creating an overall feeling of unrest. Any combination of notes will fall somewhere along this spectrum, and harmony is about balance, like light and shade in a painting.
There are 12 intervals that represent all the possible two-note combinations (dyads) within the octave: unison, minor/major second, minor/major third, perfect fourth, tritone, perfect fifth, minor/major sixth, and minor/major seventh.
Ear training:It’s important to train our ears to identify intervals instantly. Begin by choosing three intervals (unison, major third, and perfect fifth). Find a friend or an app to test yourself. Once you can identify these 95 percent of the time, add two more until you can identify all 12.
Harmony is really based on gravity, and the entire bass role is about reinforcing this.
Unison might be considered the most consonant interval, while a tritone (C to F# for example)and minor second (C to Db) might be the most dissonant. How dissonant depends on who we ask.
Consonance and dissonance are both related to real world physics via the overtone series, and psychosomatics via history and culture, or our exposure to certain sounds. I put more stock in the physics explanation. What we hear as a single note—the fundamental—is in fact an infinite number of upper partials (pitches), which together create what we perceive as a single tone. These partials are arranged in a series called the overtone or harmonic series. Expressed as comparative wavelengths, that looks like this: 1, 1/2, 1/3, 1/4, 1/5, 1/6, 1/7, 1/8, and so on. Expressed as pitches, that’s C, C, G, C, E, G, Bb, C, and so on.
Thus, taking into account all the partials involved when we combine two notes, we’re combining many notes. Each note’s partials vibrate in a manner which either reinforce or fight against the partials of the other note. The notes whose partials reinforce each other are the ones that are most consonant. Venturing further down the rabbit hole: Consonance is not based on overtone coincidence alone. It’s also based on the simplicity of the resulting ratio between two notes. Unison = 1:1, octave 1:2, fifth = 3:2, etc. (For a full explanation, see Hermann Helmholtz’s On the Sensations of Tone.)
The fifth has a very important role in harmony. People often confuse fourths with fifths. I’ll skip ahead and say the only difference between these intervals is which direction you’re going, and which note sounds like the root. The concept of “the root” is hard to explain in words. It’s a form of “harmonic gravity” that’s much easier to hear.
Exercise: Play C to F ascending and listen for which note sounds stronger—some might even say heavier or slightly louder. In most cases people will say F (the top note). Now, try the same with Fto C ascending. Most people will now hear the bottom note as dominant. Try to do the same with other fifths, and then other intervals. With all intervals, except for the tritone (more on that later), one note (the top or bottom) will consistently dominate the other, and you guessed it, once again the partials are to blame.
We could sum all this up by saying that harmony is really based on gravity, and the entire bass role is about reinforcing this. Bass instruments add weight to whatever is happening harmonically by focusing on roots and their progression. Walking bass, where we began a couple months back, is one form of this. Great bass players develop an amazing sense of where the gravity lies in any chord, or progression, and can instantly home in on it.
In the next installment, we’ll explore chord qualities, scales, modes, harmonic function, and more exercises.

Watch the official video documenting the sold-out event at House of Blues in Anaheim. Join Paul Reed Smith and special guests as they toast to quality and excellence in guitar craftsmanship.
PRS Guitars today released the official video documenting the full night of performances at their 40th Anniversary celebration, held January 24th in conjunction with the 2025 NAMM (The National Association of Music Merchants) Show. The sold-out, private event took place at House of Blues in Anaheim, California and featured performances by PRS artists Randy Bowland, Curt Chambers, David Grissom, Jon Jourdan, Howard Leese, Mark Lettieri Group, Herman Li, John Mayer, Orianthi, Tim Pierce, Noah Robertson, Shantaia, Philip Sayce, and Dany Villarreal, along with Paul Reed Smith and his Eightlock band.
“What a night! Big thanks to everyone who came out to support us: retailers, distributors, vendors, content creators, industry friends, and especially the artists. I loved every second. We are so pleased to share the whole night now on this video,” said Paul Reed Smith, Founder & Managing General Partner of PRS Guitars. “I couldn’t be more proud to still be here 40 years later.”
With nearly 1,400 of the who’s who in the musical instrument industry in attendance, the night ended with a thoughtful toast from PRS Signature Artist John Mayer, who reflected on 40 years of PRS Guitars and the quality that sets the brand apart. “The guitars are great. You can’t last 40 years if the guitars aren’t great,” said Mayer. “Many of you started hearing about PRS the same way I did, which is you would talk about PRS and someone would say ‘They’re too nice.’ What’s too nice for a guitar? What, you want that special vibe that only tuning every song can give you on stage? You want that grit just like your heroes … bad intonation? The product is incredible.”
Black Sabbath to Reunite for First Time in 20 Years—Ozzy Osbourne’s Final Performance
The original Sabbath lineup will reunite on July 5 in Birmingham, England, and be joined by Metallica, Pantera, Slayer, and more.
The concert will feature founding members Tony Iommi on guitar, bassist Geezer Butler, drummer Bill Ward, and singer Ozzy Osbourne. Profits from the show, called "Back to the Beginning," will be donated to charities including Cure Parkinson's.
On future Black Sabbath plans, Ozzy's wife, music manager, and TV personality Sharon Osbourne had this to say (via Reuters) about Ozzy: “While other bandmembers might continue to make records and perform, Black Sabbath's gig at the birthplace of the band will certainly be the 76-year-old's final performance.
"For Ozzy right now, it's definitely: 'I love you and good night'," she said.
The shredder and son of legendary artist Frank Zappa gives a tour of his up-to-date gear, including a complex stereo switching system, four racks of pedals, and some of his father’s favorite guitars.
Dweezil Zappa was always going to end up being an incredible guitarist. His dad, Frank Zappa, is celebrated as one of the most talented and creative guitarists in history, and by age 12, Dweezil was recording music produced by Eddie Van Halen. (Little surprise that he’s covering Van Halen’s 1981 stunner “Push Comes to Shove” lately.) He’s been a bona fide guitar star ever since, releasing seven original solo records, six tribute records, two LPs with his brother Ahmet Zappa, and guesting on recordings across the music universe.
Ahead of his gig at Memphis’ Minglewood Hall on his 2024 Rox(postroph)y tour, which celebrated the 50th anniversary of Frank Zappa’s Apostrophe (') and Roxy & Elsewhere records, Dweezil gave PG’s John Bohlinger a boot-to-bonnet look at his current road setup. There’s a lot of ground to cover between his and his father’s catalogues, and Dweezil loves the challenge, which he meets with a mix of his own gear and some special vintage assists courtesy of his dad.
Brought to you by D’Addario.Shut Up ’n Play Yer Les Paul
This coveted Gibson Les Paul Custom, featured on the cover of Frank’s 1981 record Shut Up ’n Play Yer Guitar, came out on the road this tour. Dweezil says that around 1986, his dad swapped in Dan Armstrong-made ceramic pickups. At one point, Frank installed a second input to try to use the guitar as a synth controller, but it didn’t track well enough to continue the experiment.
Along with the standard controls, the guitar includes switches to turn on different parts of the onboard preamp, which boosts the signal and adds plenty of gain. A rotary knob controls a wired-in parametric EQ set up to emulate different settings along the sweep of a wah pedal. Dweezil didn’t get much of the lowdown from his father on the complex operations; it was more trial-and-error. “You just have to turn knobs until you find something that you like,” he says. He connects to his rig with ZZYZX SnapJack magnetic cable connectors.
Rockin' with Roxy
Also out on the Rox(postroph)y tour is Frank’s iconic Roxy & Elsewhere-era Gibson SG. Like the Les Paul, it’s got a preamp circuit to boost the signal, a sweepable EQ, and can achieve acoustic, piezo-adjacent sounds. The preamp configuration in this one is red-hot; it dishes out tons of gain.
Signature Shabat
For Strat-style tones, Dweezil calls on his signature Shabat Lynx DZ, which has been used to dial in his cover of “Push Comes to Shove.” Per Shabat, it has a “body-mounted HSS configuration with a push/pull phase shift on the middle pickup, simplified single-knob layout, custom-cut 3-ply parchment/gold pickguard, and … a Vega-Trem VT1 tremolo."
The Lynx DZ is constructed with an alder body and a quartersawn hard maple, medium-C-profile neck with a 25.5" scale length. It’s loaded with Lollar Special S and Lollar El Rayo pickups, and the middle Special S is wired for phase shift. The Lynx, as well as the SG and Les Paul, are strung with Optima Gold-Plated 2028 FZ Frank Zappa strings (.008–.046), and struck with D’Addario .50 mm celluloid picks. (Dweezil likes them for pick slides.)
On the Ground
Zappa keeps a significant board at his feet, which he controls with a Fractal FC-12 controller. He runs his sound in stereo, with different effects going to each side, so he keeps volume pedals for each side in front of him, plus a wah and expression pedal.
The row of pedals perched atop the pedalboard includes a TC Electronic Polytune 3 Noir, a Marshall-style prototype pedal, J. Rockett Audio Designs PXO, Union Tube and Transistor Lab, SoloDallas Orbiter, a Jext Telez White Pedal (to nab a specific tone for playing “Nanook Rubs It”), and a 29 Pedals FLWR.
In the Rack
On our 2013 Rig Rundown, Dweezil was using the Fractal Axe-Fx II, and this time around, he’s upgraded to the Axe-Fx III as the basis of his sound. Given the sonic territory covered in his shows, it simply became too unwieldy and expensive to tour an analog rig.
The brains of his show are held in a rack system. A couple of out-of-sight splitter boxes help with the complex stereo signal paths, as do a pair of Voodoo Lab HEX audio switchers. The Axe-Fx III lives on the top shelf, and just below it are an Eventide H90 and TC Electronic TC 2290 that go to both sides.
The next rack down runs only to the left side, and includes a BK Butler Tube Driver, DigiTech FreqOut, Red Panda Radius and Raster, Krozz Devices Airborn Analog Flanger, and a Paul Trombetta Design Tornita! fuzz.
The level below it runs to the right side, with a “Clown Vomit” fuzz, Chase Bliss Warped Vinyl, Korg FLG-1 Flanger, Chase Bliss Generation Loss, Goochfx Holy Cow, and another Red Panda Raster.
Wrapping up the rig is the bottom rack, which again runs to both sides. It carries most of Zappa’s exquisite dirt sounds, thanks to a Union Tube and Transistor Tsar Bomba, Chase Bliss Automatone Preamp MKII, Goochfx Dirty Hippie, Tru-Fi Two Face, Foxrox Electronics Paradox TZF2, and a Paul Trombetta Design Rotobone that … somewhat reasonably apes a trombone sound. Paul Trombetta, we salute you.
