The chart ties specific slide positions to note names and partials for the tenor (B♭) trombone so you can find the best spot fast, fix intonation on the fly, and choose alternates that save slide travel or improve tone.
At-a-glance trombone notes-to-positions chart (printable quick reference)
Create a one-page map that shows note names across 1st–7th positions and common partials (2–7); design it for portrait phone wallpaper or a single printable PDF so it’s readable at a glance.
Label the map with a clear range marker for the tenor (B♭) trombone and flag notes that commonly use alternate positions or half-slide adjustments (examples: low D/B♭ area, middle-register C/D cluster, high 7th-partial A♭ area).
Include a short legend: Partial = harmonic number (2 = octave, 3 = fifth above octave, 4 = two octaves, 5 = major third above that, 6 = perfect fifth, 7 = slightly flat minor seventh); Clef = show both bass and treble labels; Transposition = mark that treble-clef tenor parts are written a whole step higher than concert pitch.
How slide position changes pitch: harmonics (partials) and slide math explained
The trombone uses the harmonic series plus slide length to make every note: you pick a partial (lip tension) and the slide length selects the chromatic pitch within that partial.
Each slide position outward lowers pitch by one semitone per position: 1st = 0, 2nd = -1 semitone, 3rd = -2, 4th = -3, 5th = -4, 6th = -5, 7th = -6; combine that with partial choice and you get the actual note.
Example: a B♭ produced in 1st position on the 4th partial moves to B (1 step down) in 2nd partial or to F (same partial but different position) depending on which partial you select; choose the partial+position combo that gives best tuning and tone.
Half positions exist because straight semitone steps sometimes miss the exact pitch due to instrument idiosyncrasies and ensemble pitch; half positions are micro-adjustments, usually 25–50% of the distance between full positions, used to correct cent-level pitch differences.
Position-by-position note map: 1st through 7th with common alternates and half positions
Below are practical, commonly used notes for partials 2–7 in each position; use these as a working reference rather than a strict rule, since mouthpiece, instrument, and room pitch will affect the exact placement.
1st position (fully in)
Common partials and pitches: p2 = B♭, p3 = F, p4 = B♭, p5 = D, p6 = F, p7 ≈ A♭. Use 1st for stability and secure center-of-tone in low-to-middle register, especially Bb, F, and D.
Alternates and half positions: low B♭ can be tuned with a slight slide-out on the tuning slide or half position if sharp; high Bb on p8 sometimes needs small outward adjustment to match pitch.
2nd position
Common pitches: p2 = A, p3 = E, p4 = A, p5 = C♯, p6 = E, p7 ≈ G. Use 2nd for quicker movement from 1st to mid-range notes and for passages that need shorter slide travel than 3rd.
Tuning notes: A and E tend to be slightly sharp on some horns; pull micro half-position outward or relax embouchure to flatten, or choose an alternate position (e.g., play written A as 1st p3 when appropriate for tone).
3rd position
Common pitches: p2 = A♭, p3 = E♭, p4 = A♭, p5 = C, p6 = C (lower), p7 ≈ G♭. Use 3rd for chromatic runs where 1–3 positions avoid large jumps.
Use half positions for fine-tuning E♭ and C area notes; 3rd position C often benefits from slight inward adjustment to sharpen when playing with a piano or guitar.
4th position
Common pitches: p2 = G, p3 = D, p4 = G, p5 = B, p6 = D, p7 ≈ F♯. Switch to 4th when you need a stable G-family tone or want to avoid long slide swings from 1st to 6th.
Practical note: B on p5 can be thin; consider alternate (shorter slide + higher partial) for more core tone in exposed lines.
5th position
Common pitches: p2 = G♭/F♯, p3 = D♭/C♯, p4 = G♭, p5 = B♭, p6 = C♯/D♭, p7 ≈ F. Use 5th for low-register choices and to reduce hand movement into full 6th or 7th.
Intonation tip: C♯/D♭ family here tends to be flat; push slightly inward or use alternate positions (e.g., play low C♯ as 4th p5 in certain contexts) to match ensemble.
6th position
Common pitches: p2 = F, p3 = C, p4 = F, p5 = A, p6 = C, p7 ≈ E. 6th is workhorse for lower chromatic notes and often needs micro-adjustment for crisp intonation.
Half positions: F and C family in 6th commonly require half-position tweaking; practice sliding to exact stops and listening to a tuner or drone to lock cent accuracy.
7th position (fully out)
Common pitches: p2 = E, p3 = B, p4 = E, p5 = G♯/A♭, p6 = B, p7 ≈ D. Full extension adds risk of wobble and slower action; favor alternates when rapid movement or matching section tone is needed.
Alternate suggestions: for exposed lines avoid full 7th when possible — pick a nearby position with a higher partial to keep consistency and reduce slide travel.
Alternate positions and pitch-savvy substitutions (improving tuning and technical ease)
Catalog of frequent alternates: low D often played in 6th p5 or 1st p4 depending on ensemble; written F above bass clef can be 6th p2 or 1st p6 depending on facility; high A♭ (7th partial) often replaced by 1st/2nd partial combos for cleaner attack.
Why alternates help: shorter slide travel reduces timing errors; different partials change overtone mix, so choose the position that balances timbre and tuning for the line.
Rules of thumb: choose the alternate that (1) reduces slide distance in fast runs, (2) keeps tone color consistent with section, (3) requires minimal embouchure change; accept a small timbre trade-off for better intonation or security.
Transposition, clef issues, and reading charts for B♭ tenor vs bass trombone
Tenor trombone is a B♭ instrument when reading treble clef: treble clef parts are written a whole step higher than they sound, so read the treble line up a major second or transpose down a major second to get concert pitch.
Bass-trombone differences: longer tubing and trigger slides change the available natural positions for low notes; bass trombones add triggers or valves that shift pitch by a fourth or fifth—account for that when using a standard slide chart.
Quick conversion tip: if a treble-clef chart shows C, the sounding pitch is B♭; confirm whether the chart labels are written or concert before you mark tape or memorize positions.
Intonation strategy: tuners, embouchure, tuning slide, and ear training with the chart
Use a chromatic tuner set to concert pitch or to show cents; play long tones on a chosen position and note cents offset, then adjust slide or tuning slide to center the pitch.
Targeted fixes: if a note reads sharp on the tuner, move the slide outward or lower the partial slightly; if flat, move shorter or increase oral cavity/air speed to sharpen.
Ear drills tied to the chart: (1) drone a concert B♭ and match each position note to the drone, (2) practice slow interval jumps between adjacent positions, (3) hold long tones while glancing at the chart until muscle memory and ear agree.
Slide technique tied to position accuracy: hand placement, slide speed, and avoiding unwanted glissandi
Hand placement: keep the right-hand grip relaxed, thumb hook around the brace, palm facing slightly up for speed and repeatable stops; mark a consistent right-hand stop point so 1st–7th are repeatable.
Slide speed and stops: practice fast-to-slow accelerations and finish with a precise stop; drill controlled legato slurs where the slide finds the exact half or full position without overshoot.
Avoiding accidental glissando: use short controlled bursts, pin the slide momentarily at target positions during slurs, and practice alternating slow slurs with metronome clicks to build timing precision.
Common trouble notes and fix-it checklist using the positions chart
Typical trouble spots: high 7th partial notes (pitch instability), low pedal notes (unstable timbre), middle chromatic notes (C/C♯, D♭/D) that sit between comfort zones.
Quick fixes: if note is sharp—move slide out a bit, lower partial, or back off lip pressure; if flat—move slide in, increase aperture focus, or add more forward air. Always check against a tuner or drone.
Ensemble fixes: match slide choices with section leaders for homogenous timbre; if section is short on time, pick the alternate that keeps everyone on the same partial or similar slide positions.
Building a practice routine around the positions chart (daily drills and progress tracking)
4-week micro-plan: Week 1 — position warmups and long tones with tuner; Week 2 — chromatic position climbs and half-position training; Week 3 — scale practice using preferred alternates; Week 4 — apply chart to repertoire and record for review.
Specific exercises: position-by-position chromatic climb (p2–p6) at metronome 60, increase tempo by 5–10 BPM weekly; partial isolation — sustain one partial while moving slide across all positions to hear cent shifts; slow metronome shifts — move slide on each click, stopping dead on the target.
Log progress: record tempo, percent-in-tune with tuner, and problem notes; set measurable goals like “cleanly shift 1st→7th at 100 BPM with <30 cents deviation” and update weekly.
Customizing and labeling your slide: slide tape, markers, and digital chart tools
Apply slide tape in narrow strips on the outer slide to mark 1st–7th; use removable cloth tape and small dots for half positions; avoid adhesives that leave residue and never use thick permanent markers that can gum up the slide.
Digital tools: use printable templates sized to your bell or phone wallpaper charts; apps that show transposing tuners and slide charts help you keep the notes handy on gigs or rehearsals.
Personal chart tip: highlight your preferred alternates in a color, mark notes that need half-position adjustments, and keep a version laminated for quick reference at rehearsals.

Quick-reference FAQ for players switching to trombone or learning positions
How many slide positions? Seven full positions; plus half positions for cent-level tuning adjustments.
Why half positions matter? They let you correct small pitch discrepancies without changing partials or embouchure, essential for ensemble tuning and quick color changes.
Best way to memorize the map? Practice consistent position drills, use tape for the first few months, and pair every position with a long-tone drone until ear and hand match.
Tips for trumpet or sax players switching? Focus on slide mapping rather than valves—train gradual slide distances, relax jaw for larger aperture control, and practice common alternates to reduce slide travel.
When to stop using tape? When you can reliably hit each full and half position under metronome pressure and match a drone within ~20 cents across standard repertoire; that usually takes weeks to months depending on practice consistency.
