A sharp line, a useful dispute

In remarks highlighted by NME, Khn, the microtonal guitarist in Angine De Poitrine, offered a defense of music-theory language with all the softness of a dropped flight case. “Value terminology. Worship terminology,” the guitarist said, before ending with a contemptuous comparison for musicians who resist it.

The contempt is where a useful argument starts clipping. Brilliant players have learned through notation, tabs, chord shapes, records, muscle memory, patient bandmates, and some combination of all six. A vocabulary gap says little about the quality of somebody’s ear. Still, the central provocation deserves a clean signal: named musical ideas can move a rehearsal faster and help an unusual sound survive from the first lucky pass to the tenth deliberate one.

The practical version belongs beside the tuner and spare strings, ready when the room gets stuck.

Theory is verbal compression

Music theory can pack a long explanation into a short instruction. Picture a bridge that feels crowded. “Take the third out of the guitar voicing, keep the bass on the root, and leave beat four open” gives three players specific moves. “Make it moodier” may also work, especially when a band shares instincts, but it usually requires a pass to decode.

An interval name, bar count, rhythmic subdivision, or chord function turns a private hunch into something another musician can try. The first suggestion may still be wrong. That is healthy. Clear language lets the room reject it quickly instead of circling an adjective for twenty minutes.

At stage volume, that economy matters. Monitors spill, cymbals hang in the air, and the change between songs is never as leisurely as it looked on the set list. A compact cue has a better chance of reaching the other side of the riser before the next count-in.

Keep the vocabulary small

A working band’s useful vocabulary can stay much smaller than a textbook. Build it from the terms its own music keeps asking for. Start with a few lanes:

  • Form: verse, pre-chorus, turnaround, tag, and ending.
  • Pulse: bar count, subdivision, pickup, stop, and where the click sits.
  • Harmony: root movement, chord quality, stable notes, and tension notes.
  • Shape: register, voicing, doubled parts, and space between instruments.
  • Delivery: dynamics, articulation, muting, sustain, and attack.

The exact dialect can vary. The Nashville Number System, Roman numerals, chord names, fret numbers, sung notes, and hand signals can coexist if everybody knows the translation. If one player says “flat five” and another knows that sound as a familiar fretboard shape, connect the two references once and carry on.

Avoid turning a good take into a spelling hearing. Enharmonic detail can matter in a chart or a tuning plan, but a rehearsal has priorities. Write recurring cues in the shared set notes, define unfamiliar language without theatrics, and keep the vocabulary close to the songs. A useful page might simply say “two-bar stop, bass pickup on four, guitar enters high.”

Microtonality raises the stakes

Microtonality is an umbrella for pitch organization beyond the familiar 12-tone equal-tempered grid. Standard fretted guitars and piano-roll editors put that grid directly under the fingers. Once a piece reaches between or outside those fixed positions, “a little lower” can get one player close while leaving another to guess.

This is where terminology earns practical weight. A group might use a ratio, a cents offset, a scale degree within a named tuning, or a recorded reference pitch. No single method covers every microtonal practice. The goal is repeatability inside the chosen system.

Physical setup matters too. Retuning changes the relationships between open strings. Deliberate bends demand repeatable touch. Pitch processing introduces tracking and control choices. Alternate fret layouts redraw the geography under the fretting hand. Those routes can reach related pitch territory while feeling completely different to play.

A clear label preserves the target as the rig changes. The odd pitch can leave the pale stripes of the default piano roll, pass through a rehearsal recording, and return at soundcheck with its edges intact.

Gatekeeping adds noise

Theory loses allies when terminology becomes a password. An ear-trained musician may hear tension and release with precision while lacking classroom labels. A fluent reader may identify every note and still miss the pocket. Those are different competencies, and a serious rehearsal can make room for both.

Useful theory etiquette is plain:

  • Pair the term with a sound. Say it, then sing it, clap it, or play it.
  • Ask which system the group already uses before introducing another one.
  • Correct the arrangement or execution without grading a person’s intelligence.
  • Keep definitions brief during the take, then revisit them during a break.

These habits keep standards attached to an audible result. They also expose empty jargon quickly. If a person cannot demonstrate the “advanced” idea or explain what should change in the next pass, the term is decorating the problem.

Nobody needs that lecture while the amplifier is humming and the drummer is holding sticks above the count-in.

Run the fifteen-minute check

Try a compact check at the next rehearsal:

1. Choose eight bars that keep producing vague feedback or inconsistent takes.
2. Play the section once without interruption. Make a quick room recording if everyone agrees.
3. Let each player describe one important event using whatever language is available: a chord name, a shape, a sung pitch, a rhythmic syllable, or a physical gesture.
4. Translate those descriptions into two or three cues everyone understands.
5. Change one variable, play the section again, and compare the result.

A player who cannot name an interval can sing it. Another musician can supply the term, and both references can remain in the notes. For a microtonal passage, save a starting reference plus the group’s agreed pitch description. That might be a tuning label, an offset, or a short audio example.

The second pass tells you whether the vocabulary earned its place. Keep cues that produce a clearer entrance, tighter spacing, or a repeatable pitch. Replace any phrase that sends the room into fog. Put the final wording beside the tuning and count-in notes, where it can survive a noisy soundcheck and a substitute player.

Theory at floor level

Khn’s provocation catches a real frustration. Anti-theory swagger can turn avoidable confusion into hours of vague takes. A hierarchy of players only creates another distraction. Terminology should face the same test as a cable label, tuner, or strip of fluorescent tape on the floor: does it help somebody act accurately under pressure?

Use the term when it speeds a change, preserves an unusual tuning, or gets an entrance to land. Translate it when the room stalls. Teach it without the sneer. The best defense of theory is sitting in the playback, where four musicians hit the same odd interval while the red recording light is still on.
