Trombone
The trombone offers unique pitch flexibility through its slide, but this means positions are approximations that must be adjusted by ear. Standard positions are starting points, not absolute.

Common Pitch Tendencies
- Slide positions vary based on partial, temperature, and instrument
- Higher partials require shorter positions than lower partials
- Sharp side of position = more toward bell (shorter)
- Flat side of position = more toward you (longer)
- F attachment changes all positions when engaged
- Cold slide = all positions need to be longer
- Upper register tends sharp
- Lower register tends flat
- Each trombone has unique position quirks
🌡️ Temperature & Warm-up
Slide positions change significantly with temperature. Cold instrument requires longer positions. Warm up both yourself and the instrument.
Register Guide
Low Register
Low register (pedal Bb–F3): Positions tend flat in cold conditions. Use longer positions than marked. Pedal tones require embouchure flexibility and are notoriously unstable in tune.
Middle Register
Middle register (F#3–Bb4): Most stable range. Position 1 (Bb) and position 4 (D/G) are reliable anchors. Focus on tone quality here.
High Register
High register (B4–D5+): All positions trend sharp as partials tighten. Use shorter positions and lighter embouchure pressure. Avoid locking the slide position — allow micro-adjustments.
F-Attachment
F-attachment notes: When engaged, all positions shift roughly ½ position shorter. F3 = 1st position (F trigger), E3 = 2nd, etc. Intonation varies by instrument — learn yours specifically.
Note-by-Note Tendencies
| Note | Fingering / Position | Tendency | Adjustment |

🔧 Equipment & Setup
🎵 Mouthpiece
- Larger cup (e.g., Bach 6½AL vs 12C) = darker tone and slightly flatter tendency
- Shallower cup aids upper register brightness but can be sharper
- Wider bore (0.547"+) requires more air but gives more flexibility for pitch adjustment
- Rim diameter affects comfort and endurance over long sessions
- Hard rubber vs metal cups — both affect resonance and pitch center
🔧 Instrument
- F attachment: engaged by trigger/thumb lever — positions shift approximately ½ position shorter
- Main tuning slide: pull to flatten overall pitch for warm rooms; push in for cold environments
- Larger bore (bass trombone) requires longer position extensions in low register
- Water key placement affects resonance in some positions
- Lightweight slide affects position feel — heavier slides have better feedback
💡 Practice Tips
- Adjust 5th-position F to "long 5th" (slightly past the bell stay) — most horns sit ~10¢ sharp at marked 5th
- Use "flat 2nd" for B natural and "sharp 5th" for A — both compensate for natural partial drift on those slots
- Use alternate positions across slurs (D in 1 → C in 6) to smooth legato without crossing partials
- F-attachment positions run progressively shorter — 5th-position F-att is ~1/2 position shorter than open 5th
- Drone-sustain low Bb (1) and F (1) — these are tuning anchors; if these are off, every other position drifts with them
- The 7th partial (high-Eb area) is naturally 30¢ flat — lip up or shorten the slide visibly to reach equal temperament
- Cold slide flows differently from warm — re-tune main slide after 10 minutes of playing rather than from the case

Ensemble Intonation
Ji Deltas Instrument
- major-third
- perfect-fifth
- harmonic-seventh
- major-sixth
Section Role
- Bass voice (tuba / bass trombone) holds the root — others tune to it, not to a piano
- Always tune the perfect 5th UP from the root by ~+2¢ (Just), not 12-TET
- The major 3rd is the load-bearing pitch: flatten by ~14¢ from ET against the root
- In dominant 7th chords (V7), flatten the b7 by ~31¢ (harmonic 7th) for the classic "fat" brass blend
- Lead trumpet often plays slightly sharp to project; rest of section tunes to a section A
- Mute the bell when checking sectional intonation in rehearsal — clearer beats
Harmonic Series
- 2nd partial (open fundamental): in tune by design
- 3rd partial: ~+2¢ sharp from ET (just perfect 5th = 702¢)
- 4th partial: in tune
- 5th partial: ~-14¢ flat from ET (the natural major 3rd) — players consistently lip up
- 6th partial: ~+2¢ sharp (just perfect 5th from the octave)
- 7th partial: ~-31¢ flat (harmonic 7th) — unused in modern playing, always altered
- 8th partial: in tune
- 9th partial: ~+4¢ sharp (just major 2nd)
- 10th partial: ~-14¢ flat (major 3rd, again)
Genre Pitch Center
- Concert band: A=440 standard
- Orchestra: A=440 in US, A=442 in many European orchestras
- Jazz: A=440; lead trumpet often plays +3¢ to +8¢ sharp to cut through the section
- Symphonic brass: tune to the bass voice (tuba) — not to oboe — in section work
Overrides
- Trombone section has continuous pitch adjustment via slide — use this as section glue
- In jazz big-band, lead bone tunes to lead trumpet, NOT to its own section pitch
- In symphony, bass trombone holds the root; tenors voice the 3rd/5th relative to bass
- Glissando: any pitch is reachable — but TARGETED arrival pitches must use the JI deltas
Mute Effects
Straight mute
- Pitch Effect:
- +10¢ to +20¢ sharp
- Tone Effect:
- Bright, focused — common big-band ballad mute
- Adjustment:
- Extend main tuning slide; check with a drone
Cup mute
- Pitch Effect:
- +5¢ to +15¢ sharp
- Tone Effect:
- Mid-warm, slightly distant
- Adjustment:
- Small slide adjustment
Harmon (Wick / Denis Wick)
- Pitch Effect:
- +5¢ to +15¢ with stem in; -10¢ stem out
- Tone Effect:
- Edgy; works for jazz solo lines
- Adjustment:
- Adjust stem first, slide second
Plunger
- Pitch Effect:
- Negligible open; +5¢ to +15¢ as plunger closes
- Tone Effect:
- Most-used trombone effect mute; vocal "wah" character
- Adjustment:
- No physical slide adjustment — compensate with lip and ear
Bucket (Humes & Berg)
- Pitch Effect:
- -2¢ to -8¢ slightly flat
- Tone Effect:
- Softens edge for section pads
- Adjustment:
- Generally none
Whisper / practice mute
- Pitch Effect:
- +15¢ to +30¢ sharp + heavy resistance
- Tone Effect:
- Practice tool only; not for performance
- Adjustment:
- Do not use for intonation training
Slide & Position Notes
- 7-position slide system: each position is a perfect 4th lower than the previous open partial
- 1st position: should match a tuned open Bb; if not, adjust main tuning slide
- 6th position: tendency to be SLIGHTLY short — most players use 6th slightly past detent
- 7th position: low E natural tends sharp because slide drags; extend an extra inch on sustained notes
- F-attachment: the F valve adds tubing; 6th-position F can be played in 1st-position-on-F-valve for legato
- Fast trills/lip slurs: use shorter slide moves (alternate positions) over long throws
