Interpreting memories, wrangling frequencies, and exploring the importance of well-designed studio rooms.
We all have a few moments in our musical journeys that we'll always remember—from the first (or worst) gig to the people we've met and played with. One of my most memorable was my first time in a well-equipped recording studio, especially upon hearing my bass through some huge JBL studio monitors in the control room. When the tone kicked in with previously unknown dynamics and my notes had an abrupt end with no echo or delay, it was worlds away from what I knew from rehearsals. I loved how the notes chimed in with no build-up time or decay. Of course, it all had nothing to do with my abilities. It was simply just the excellent room acoustics that we weren't able to create in our rehearsal room.
Studios have that special atmosphere of an acoustically dead room, and nailing egg cartons or carpets on the wall isn't really going to accomplish the same thing. Sure, that may dampen the sound, but it's the upper end—not the low end—that causes the majority of problems in room acoustics. So getting that bass range under control will require more than egg cartons and stinky carpets, but it's worth it, even in a rehearsal room.
It's common to look at frequencies of up to 300 Hz as the low range, but keep in mind that a guitar's B-string has a fundamental frequency of roughly 250 Hz. So, if your band is going to invest in acoustic improvements, the guitarist has to pay his share and so does the drummer!
Every room has its modal responses, aka “eigenmodes," where—as opposed to a free field—waves will be bounced back from the walls and mix with those of the signal source. This is called wave cancellation and happens at all frequencies. However, due to the long wavelength of low notes, the points of a low-end signal's buildup of sound pressure (constructive interference) and cancellation (destructive interference) are much further apart, making them way more noticeable. In fact, this makes it impossible to hear all bass frequencies (not just the eigenmodes) at the same volume at every point in a room.
The effect is called Speaker Boundary Interference Response (SBIR), and the peaks and nulls it creates are entirely due to the distances of various surfaces in a room. The problem is that we not only have a lot of sound sources in a typical rehearsal room, but our low-end bass signal is omnidirectional. High frequencies spread more like a directed beam, while low frequencies spread in all directions from the source, which means that we have to take far more boundaries into account. It's not just the wall the speaker is pointing at, but also the one behind it. This causes a multitude of problematic frequencies at different points in the room, and can give the phrase “I can't hear my bass!" literal meaning.
Unfortunately, it doesn't end there, as there is also a lesser-known effect that is simply annoying for everyone trying to keep a groove. We know we can get extended decays at different points in a room, but this effect doesn't just result in a different tonal perception at different locations or a decay or sort of echo when the signal stops. The very same decay is happening when the tone builds up. And it can easily be as long as a fraction of a second. So much for playing in time!
Studios take on great effort and expense to get these effects under control, since recording or rehearsing in a free field isn't normally an alternative. Otherwise, the sound of productions would be highly dependent on the rooms they're recorded and mixed in.
Next month, let's explore the possibilities and limits of studios, and see some options for smaller budgets.
Kick off the holiday season by shopping for the guitar player in your life at Guitar Center! Now through December 24th 2022, save on exclusive instruments, accessories, apparel, and more with hundreds of items at their lowest prices of the year.
We’ve compiled this year’s best deals in the 2022 Holiday Gift Guide presented by Guitar Center.
DiMarzio, Inc. announces the Relentless P (DP299), the Relentless J Bridge (DP301), Relentless J Neck (DP300), and the Relentless J Pair (DP302) for 4 string basses.
DiMarzio, Inc. announces the release of the Relentless P (DP299), the Relentless J Bridge (DP301), Relentless J Neck (DP300), and the Relentless J Pair (DP302) for 4 string basses. The new Relentless P and Relentless J series pickups feature the Relentless cover designed in collaboration with Billy Sheehan.
As with the Relentless pickups, we removed all the hard edges from the standard P Bass and standard J Basspickups, and added an arch to the top of the pickups to bring the sensing coils and pole pieces closer to the strings. These improvements increase the dynamic range and make active circuitry unnecessary.
The Relentless P and Relentless J pickups incorporate Neodymium magnets and produce 70 percent more output than traditional passive pickups, and they’re dead quiet due to the incorporation of metal covers and foil-shielded cables. To dial in (or fine-tune) the individual string output, the Relentless P and Relentless J include eight adjustable pole pieces. These pickups also have a broad magnetic field so you can even bend notes without volume dropout.
DiMarzio’s extra shielding makes the Relentless P and Relentless J better for both recording and stage performances. We’ve mounted them onto robust .09375” thick circuit board base plates to eliminate the annoying protruding mounting screws — ultimately creating a more comfortable and consistent foundation to rest your fingers on.
The new Relentless P steps beyond the traditional P-Bass sound and can only be described as massive. It has more of everything: more volume, beefier lows, a growling midrange, and crispy highs with better individual string definition.
The Relentless J incorporates a new invention, (patent pending) parallelogram-shaped coils, offering an expanded mid-range punch, snappy highs, precise lows, and a new dimension to the sound of the Relentless series pickups.
Relentless P and Relentless J pickups will breathe new life into any bass, increase playability, and work well for any style of music from Motown to metal.
DiMarzio’s Relentless P, Relentless J Bridge, Relentless J Neck, and Relentless J pair are made in the U.S.A. and may now be ordered for immediate delivery.
Suggested List Price for the Relentless P is $169.00 (MAP $119.99).
Suggested List Price for the Relentless J Bridge and Relentless J neck is $155.00 (MAP $109.99).
Suggested List Price for the Relentless J Pair is $296.00 (MAP 209.99).

For part two of our crash course in harmony for bassists, we’re talkin’ triads.
As bass players, our job is often to indicate and support what is happening rhythmically and harmonically in the music we’re playing. And to do that, it’s important for us to understand the basics of tonality and how it works. In fact, every bass player must have a strong knowledge of harmony to do their job correctly. This month, we’ll continue last month’s harmony crash course with some more ways to brush up on your ear skills, in italics below, so you can do your low-end job effectively.
The basic building block of harmony is the dyad, which gives us our basic intervals. But the basic building block of tonality is the triad, a grouping of three or more tones (root, 3rd, and 5th) that give us the four chord qualities—major, minor, diminished, and augmented—which you’re probably already familiar with.
Just as with intervals, we should train our ears to recognize chord qualities instantly. Start with two qualities (major and minor). Once you can identify those two correctly about 95 percent of the time, add another. Keep going until you can identify all four qualities consistently.
Another great exercise is to take a melody (either major or minor) and convert it to the opposite quality. Start out with something you know well, like “Twinkle, Twinkle, Little Star.” This may take a while at first, but the goal is to keep on doing these until you can convert most stuff on the fly instantly.
“This feeling of resolution, in some ways, is the whole point.”
Each chord quality has its own distinct sound, but major and minor are related, and both feel very grounded. Because of the 5th in each, our ears can easily hear which note in the chord is strongest (the root), which gives major and minor a sense of gravity. This feeling persists even if we change the order of the notes (invert the chord).
Have a friend or an app play inversions of major or minor triads. Find the root of each chord by singing it. Work towards being able to identify these triads in root position (root in the bass), first inversion (3rd in the bass), or second inversion (5th in the bass).
Pay attention to bass lines that land on a root, 3rd, or 5th on the first beat of the bar and then practice coming up with your own examples.
Diminished and augmented triads are much more ambiguous. Without a perfect fifth (diminished has a b5 and augmented has a #5), no tone in particular sounds strongest. Thus, both chords lack gravity. In fact, to most of us, every tone sounds equal, like being lost in the woods where every direction appears the same. Both seem to want to move towards something else more stable. When this occurs, it gives a sense of release, or resolution. This feeling of resolution, in some ways, is the whole point.
The top part of a dominant seventh or V7 chord is a diminished triad. For example, a C7 consists of the notes C–E–G–Bb. If you remove the C, we’re left with an E diminished triad. This is where the moving sound, or the desire to resolve, comes from. The important takeaway is that we’re making something very stable—a major chord—and making it less stable when we add the b7, because of the diminished sound, which in turn sets up the need to resolve.
Listening for V–I: On a guitar or keyboard play any major chord, then add a b7 (transforming I to V7) and try to hear where the progression “wants” to go next. Move to the new key (a fifth down) and repeat. After twelve V–I progressions you’ll arrive back at the original key.
The Dominant Gateway: On bass, try playing a walking bass pattern over the cycle of fifths, strategically using a b7 to move to the next key. This foreshadowing is a great voice-leading skill.
That's all for our crash course in harmony. If you take your time with these exercises, you should notice not only your ears improving, but your bass playing too!
