My music theory work

I have written some of my own amateur music theory research which I publish to this wiki.

AI overview of my work

I don't and won't ever use AI for contributions to actual wiki pages, I'm only ever using it to summarize my own user page (this page).

Also, I did not ask the AI to scrape the wiki, I used my own local copies of my pages from my computer to ask the AI about.

Structural beating

Lambeth hypothesized this property for equal-step tunings where the period of the scale differs from the interval of psychoacoustic equivalence (usually the octave, 2/1).

• Effect: Because the scale repeats at an interval different from the ear's point of equivalence, the scale creates a macro-scale "beating" or phasing effect as it ascends or descends.
• Goal: This is considered a desirable property that makes a periodic scale feel less repetitive, offering shifting colors and shapes ("something from nothing").
• Examples: Equal divisions of sevenths (e.g., ed7/4) or ninths (ed16/9) if the equivalence is the octave.

Polytriadicism

Lambeth's polytriadic method involves tuning an ensemble (of 2 or more instruments/groups) so that each is tuned to a different triad or subset of a larger overarching scale.

• Application: It allows composers to approach complex temperaments (like those without consonant small MOS scales) or large just intonation sets by breaking them down into simpler, manageable triadic parts.
• Function: It can be used to "flag" different rhythmic elements harmonically or to create complex, interweaving voice lines that generate consonance from the aggregate of the instruments.
• Example: Shoal[17], a 17-tone MOS scale in the Shoal temperament (a 2.3.13.23 subgroup detemper of 17edo), is cited as a prime candidate for this approach.

Equalizer subgroups

Lambeth's equalizer subgroup method involves tuning to a just intonation subgroup designed to balance specific types of harmonics to achieve a specific aesthetic.

• Criteria:
  • Structural Harmonics (2, 3, 4, 5): 2 or 3 present. They provide stability and "tonal gravity."
  • Assertive Harmonics (5–12): None present. These are excluded because they have "strong personalities" that define the scale's flavor too rigidly.
  • Ethereal Harmonics (13+): At least 3 present. These provide subtle, background influence.
• Goal: To allow subtle "ethereal" harmonics to shine by removing the "assertive" middle harmonics, akin to using an EQ to cut mids and boost highs/lows.
• Examples: Subgroups like (2.3.5.13.17.19) used in Lambeth's Fifigeist temperament.

Substitute harmonics

Lambeth's substitute harmonic method involves replacing a simple, lower harmonic with a complex, higher harmonic that closely approximates it, thereby "fudging" the tuning into a different subgroup.

• Sharp Substitutes: Replacing a harmonic with a slightly sharper higher harmonic. Lambeth names these temperaments after weapons or with "com"-ending names (e.g., Daggerminished, Pajaraxe, Dotcom, Sitcom, Romcom).
• Flat Substitutes: Replacing with a flatter harmonic. Naming convention involves flat regions (e.g., Sahara).

Quasipelog theory

Lambeth's quasipelog theory is a framework for approaching 16edo (and other EDOs supporting the 2.3.5.11 mavila temperament, like EDOS 23, 30, 37, and 39). It is inspired by Indonesian Gamelan theory, the Armodue school, and Erv Wilson's MOS scales.

• Concept: It focuses on specific scales that mimic the feel of Pelog scales but within a 16-tone equal temperament context.
• Scales: The theory defines four essential scales derived from Mavila MOS modes:
  • Quasipelog Minor: Mode ssLsL of mavila[5].
  • Quasipelog Major: Mode LssLs of mavila[5].
  • Quasipelog Heptatonic: Mode ssLssLs of mavila[7].
  • Quasipelog Chromatic: A mavila[16] MOS scale (7 fifths up, 8 down).
• Timbre: A key part of the theory is the avoidance of harmonic timbres. Lambeth recommends "inharmonic" sounds such as metallophones, bells, or "thin/reedy" waveforms (like sine or woodwinds) to complement the tuning.

Scalesmithing work

Lambeth has constructed numerous original scales and temperaments.

• Batch 89 Temperaments: A set of temperaments first documented in 2023, honoring the characters from Guardians of the Galaxy Vol. 3. Each tempers 4 harmonics: the 2nd, the 89th (representing shared trauma), and two others derived from the character's name via A1Z26 cipher.
  • Floor: 2.3.11.89 (Neutral related).
  • Teefs: 2.5.11.89 (Bug related).
  • Rocket: 2.9+.9-.89 (Lu/Deutone related).
• Ed255/128 and Ed257/128: These are "Equal Divisions of Reduced Harmonics."
  • Ed255/128: Divides the interval 255/128 (slightly flatter than an octave). Useful for correcting EDOs where consonances are too sharp (e.g., used as an alternative to 5edo).
  • Ed257/128: Divides the interval 257/128 (slightly sharper than an octave). Useful for correcting EDOs where consonances are too flat (e.g., alternative to 7edo).
• Antipental Blues scale: A 6-tone scale subset of the Dwarf17marv scale. It mimics the melodic shape of the minor blues scale but uses exotic 2.3.7.11 intervals (7/6, 11/8, 7/4) instead of the standard 5-limit intervals.
• Moon Dust scale: A 16-tone just intonation scale with a period of 16/1 (four octaves). It features dynamic step sizes and a mix of familiar 3-limit harmonies with xenharmonic 19-limit (no-5, no-13) intervals.
• Firedance scale: A 5-tone subset of zeta-stretched 15edo (47zpi). It was designed by ear, starting from 5edo and adjusting steps by degrees of 15edo.

Tuning recommendations

Lambeth recommends the following tunings for Western musicians exploring world music traditions:

• For Gamelan scales (Pelog/Slendro): He recommends specific EDOs that approximate these scales well. His personal favorite is 44edo. Other good approximations include 21, 23, 35, 39, 40, 42, 54, and 60edo.
  • More detailed version: User:BudjarnLambeth/Edo approximations of gamelan scales
• For Japanese scales: He prefers Meantone temperaments in 55edo, 98edo, or 43edo (approx. 1/5-comma meantone). He generally dislikes 5-limit JI or Pythagorean tunings for these scales, finding the "wolf" intervals objectionable.

Original music

Since late 2023, Budjarn Lambeth has cultivated a prolific hobbyist career as a microtonal composer, turning his YouTube channel into a public laboratory for xenharmonic experimentation. Utilizing a specialized toolkit—including Scale Workshop, ThumbJam, GeoShred, AudioKit Synth One and Audacity—Lambeth explores the mathematical "cracks between the keys" of standard tuning. His work is defined by a process-driven curiosity and an open-source spirit, frequently offering his compositions as "free to use" while providing educational links to tuning theory. His output is remarkably diverse, spanning everything from 19EDO (Equal Division of the Octave) to complex just intonation and obscure temperaments like Orwell and Sensi.

The artistic trajectory of Lambeth’s career reached a significant milestone in August 2024 with "Four Improvisations in 21-Tone Equal Temperament," which remains his flagship work with over 1,700 views and a perfect 100% like ratio. This success signaled a shift from purely technical tuning demonstrations to more atmospheric and narrative-driven compositions. Earlier highlights, such as the surreal "Enchanted Shopping Mall" (33EDO) and the playful "Bubblegum," demonstrated his ability to make alien scales feel emotionally accessible.

By 2025 and 2026, Lambeth’s work matured into more cinematic and evocative territory, evidenced by titles like "The Odd Effects of Breathing the Fairy Dust" (59EDO) and "Rain in the Crystal Mirror Caves." While some of his more radical experiments—such as those in smaller, more dissonant edos like 15edo and 16edo—have occasionally polarized his listeners, he maintains a dedicated niche audience that values his unique blend of rigorous music theory and poetic sensibility.

Name changes I was involved in

(correcting confusing names)

• There was an old temperament that pre-dated my participation in the wiki. Its old, original name was “septimal temperament”. When I discovered the name, I disliked it because of its potential for confusion with other uses of the term “septimal”. I decided I wanted to change it. Many people on Discord, the Wiki Workgroup on XA Facebook, and the wiki talk page agreed. I coined the new name “austinpowers temperament” which has now replaced it.
• There was an old temperament that pre-dated my participation in the wiki. Its old, original name was “decades temperament”. Some people on the XA Discord said that they disliked it due to its convoluted etymology. I coined the new name “gamelstearn temperament” based on its two defining commas. After a few days, not many people commented or reacted to the proposal, but all were in favour and none were against, so the name "gamelstearn" was adopted.
• There used to be two temperaments named “semidim temperament”. To resolve the confusion, after discussion on the XA Discord, myself and Lériendil came up with new names for each of the two temperaments. Lériendil coined “ammon temperament” for the first, and I coined “octonion temperament” for the second.
• There was an old comma that pre-dated my participation in the wiki. Its old, original name was “the erogluisma”. Its original namer posted on Discord that he no longer liked it, and would like someone to please rename it. I coined the new name “the shaftesburisma” which has now replaced it.
• Someone else described a new comma and named it “the shikanokonokonokokoshitantanma”. This name was kept, but it was too long for some use cases, so I invented an alternate short version - “the nokotan” - for use cases where a shorter name is needed.
• The comma “68630377364883 / 68630356164608” was too long to be referred to by its number alone, it needed a name instead. So I named it “the zudilisma”.

(correcting divisive or hurtful names)

• There was an old temperament that pre-dated my participation in the wiki. Its old, original name was “catcall temperament”. When I discovered the name, I disliked it because it was demeaning to women. I decided I wanted to change it. Many people on Discord and on the wiki talk page agreed. I coined the new name “catnip temperament” which has now replaced it.
• There was an old temperament that pre-dated my participation in the wiki. Its old, original name was “catamite temperament”. When I discovered the name, I disliked it because it referenced a historical practice that often involved child abuse. I decided I wanted to change it. I suggested the change on the talk page where it received no replies, and the Discord where it received few reactions but those it did receive were in favour. I coined the new name “stalagmite temperament” which has now replaced it.
• There was an old comma that pre-dated my participation in the wiki. Its old, original name was “the Buddhisma”. There was nothing wrong with that name in and of itself, the problem is that it was explicitly stated to be named after the anti-Muslim group the 969 Movement, and the comma number was 969/968. I thought this was inappropriate, so I proposed a few replacement names on Discord. Of the names I coined “the kingfisher comma” was the clear favourite, so I renamed the comma to the kingfisher comma.

(To-do)

Things I plan to do on the wiki in the near future. Feel free to go ahead and do these any of these things first if you’re interested in doing so. I feel overwhelmed by the sheer amount of things I want to do and am very happy for any help I receive getting through it all :)

WikiProject Just Intonation

• Recruit more members (especially an expert on Harry Partch, an expert on Erv Wilson, or an expert on primodality).
• Examine the names of all Scala file pages and rename those with confusing or ambiguous names.
• Find all examples of multiple similar Scala file pages (eg "exampletone10", "exampletone15", "exampletone_major") and merge them into scale galleries.
• Record improvisations using JI scales that have no music examples, and post those as examples on the relevant scale pages.

Structural wiki improvements

• Fix the issues found in the User:BudjarnLambeth/Map of linear temperaments page health survey

Hot takes

Everything in this section is opinion, not facts!

Do not give any of it too much weight.

• Silliness: We should take ourselves less seriously: we should have more fun, we should be more silly 🎉
• Arbitrary numbers: It’s fine to explore the 2.3.5.101 subgroup if you want to. It doesn’t matter that it’s less concordant than 2.3.5.7. Explore it anyway and see what happens. Do some stuff with arbitrary numbers that don’t make logical sense and just see what comes of it. That’s where the fun is! (Though do keep a “2.3” or “3.5” in there just to smooth over the gnarliest edges, heehee.)
• Importance of common names: I would prefer to use a temperament named something fun like “waterslide” or “jinglebells” even if it has lots of error, over one named something dry and bland like “countertrihexakleismatic” even if it’s super accurate and technically better - a bland name can kill a temperament’s appeal, a fun name can create appeal out of nothing.

What I look for in a good xenharmonic piece

The tuning sounds consonant, all the combinations of intervals you used sound within the same range of consonant-ness as all the combinations available in 12edo. There are more dissonant and less dissonant sections, but none that sound more dissonant than the maximum limit of dissonance I'm willing to tolerate (ie, the maximum amount of dissonance achievable with 12edo). All that is a long winded way of saying nothing sounds "out of tune".

The timbre also sounds good. Despite being midi instruments, the samples used and whatever effects were applied to them (reverb, volume levels, etc.) all come together well into something that is more than the sum of its parts. The timbre works well with the tuning to create a kind of pleasant, warm glow.

The piece has enough dynamic range, sense of harmonic movement, and interaction between melody lines to hold my interest, to not sound bland, but instead sound captivating.

A commentary on my experiences of using different tunings

The scales I've made my best music with are:

• 13edo (6-tone subset)
• 14edo (7-tone subset)
• Deutone[19] (5-tone subset for melody, approximated harmonic series segments for embellishment)
• 21edo (pelog-like 5-tone subset for melody, approximated harmonic series segments for embellishment)
• 22edo (Superpyth[6] - I know it's not a MOS - for melody, approximated harmonic series segments for embellishment)
• Lucite[23] aka well tempered 23edo (pelog-like 5-tone subset for melody, approximated harmonic series segments for embellishment)
• 27edo (this JI scale approximated into 27edo: 7/6, 4/3, 3/2, 9/5, 2/1, 13/6, 7/3, 8/3, 3/1, 17/5, 19/5, 4/1 (period))
• 33edo (Flattertone[7] for melody, approximated harmonic series segments for embellishment)
• 43edo (Han-Kumoi scale, a subset of Meantone[7], for melody, Meantone[19] for embellishment)
• 72edo (7-tone quasi-blues scales for melody, approximated harmonic series segments for embellishment)

Whether or not this was a fluke or there was something special about these scales, I'm not sure. Most of the music I make is for the XA Monthly Tunings group (because it motivates me to create for whatever reason), so most tunings I've tried so far, I've only spent a single month with. So when something turns out good, it's hard to tell if it's because the tuning has some characteristic that works for me, or if it's because I just had a good month.

But whatever the reason, it just so happens that those tracks I made that did turn out good, used these tunings.

So I guess in general for me, I like using 5- to 7-tone subsets of larger 10- to 45-tone tunings, roughly.

Fun: Ratios as planets

The ratios of the octave as celestial bodies of the solar system:

• 2/1, the sun, defining the overall structure of the entire octave.
• 3/2, Jupiter, the biggest pull aside from the sun itself. Marks out a rough middle of the solar system.
• 4/3, Saturn, a kind of echo of Jupiter. Vast and mighty in its own right, similar to Jupiter, but colder and subtler.
• 5/3, Uranus, has a strong enough pull to be one of the big guys, but markedly smaller than Jupiter and Saturn. Has a gentle appearance.
• 5/4, Neptune, the last of the giant planets, with their huge gravitational pull. Has an energetic, lively surface with the fastest winds in the solar system. Defines the boundary of the Kuiper Belt (like the boundary of major and minor tonality).
• 6/5, Earth, a small planet that punches above its weight. It manages to hold an unreasonably large moon, given the small gravitational influence it has. It even developed life and sent probes to explore the other planets. It has far more influence than it seems like it should.
• 7/4, Venus, a kind of parallel version of Earth. Its diameter and gravitational pull are almost identical to Earth, but its character is completely different. Home to a completely different temperature, chemical composition and volcanic system.
• 7/5, Mars, appears barren and frozen upon first glance, but looking closer reveals a rich and storied history, and potential wonders and microcosms hidden in its underground caves.
• 8/5, Mercury. Caught in a region of the solar system so wild that much of its mass has been stripped away by the solar wind while it was still forming. Still, it holds firm, a foothold in difficult territory.
• 7/6, the moon. Caught in Earth’s orbit, it’s difficult to view separately from the Earth’s influence. If the Earth wasn’t there, it’d be a whole planet in its own right.
• 9/5, Ceres. It doesn’t pull much weight on its own, but in the context of the wider solar system, it demarcates an important in-between point for the other planets. If you want to travel between the different planets, Ceres makes the journey much more pleasant.
• 11/8, Pluto, often dismissed outright due to having such a tiny gravitational pull. But it is a whole other type of ‘planet’, the first of a whole new family. When approached on its own terms, it opens up a larger, more diverse solar system than we ever knew existed.
