Common Pitch Tendencies
- Reed and bocal selection critical
- Many alternate fingerings available
- Upper register tends sharp
- Low register stable but needs support
- Tenor register most problematic
- Flicking (A3–D4) prevents cracks and grunts on slurs and attacks — it fixes response, not pitch
- Half-hole technique affects pitch
- Temperature acts on the air in the bore, not the wood: a cold bassoon plays flat until your breath warms it
- The whisper key must stay down from E2 up through G#3 (Ab3); below E2 the low E key closes the whisper pad — a forgotten or leaking whisper key destabilizes low-register pitch and lets notes crack up to the next partial
Temperature & Humidity
A cold bassoon plays flat; pitch rises as warm breath heats the air column (true of every wind instrument — the body's own expansion is negligible). The wooden body conducts heat slowly, so let it acclimate to the room and warm up before tuning.
Register Guide
Low Register
Low register (Bb1–E2): Good stability with proper support. Requires full, warm air column. Rarely problematic for intonation if breath support is adequate. Lowest notes (Bb1, B1) need extra attention.
Middle Register
Middle register (F2–E3): Most reliable register. Standard fingerings are stable here. This is where you set your reed/bocal combination for best overall intonation.
Tenor Register
Tenor register (F3–B3): The most challenging for bassoon intonation. Flicking (briefly touching the A/C/D thumb keys as A3–D4 begin, especially on slurs from below) keeps notes from cracking or grunting — it fixes response, not pitch. Half-hole technique on F#3, G3, and Ab3 must be precise.
High Register
High register (C4+): Trending sharp +5 to +25¢, increasing with each note. Embouchure control and voicing adjustments critical. Alternate fingerings often necessary above E4. The top of the range (roughly Bb4–E5) requires specialized practice and instrument-specific fingerings.
Fingering Chart
Every note in written pitch, the standard fingering a teacher would start you on. Filled keys are pressed, half-filled is a half-hole, outlined keys stay open. Alternate fingerings are drawn in the table below.
Note-by-Note Tendencies
| Note | Fingering / Position | Tendency | Adjustment |
|---|---|---|---|
| Bb1 | Low Bb (all keys) | -5 to +15 | Often sharp on many horns — maximum support, open throat; map your own instrument |
| B1 | Low B | -5 to -10 | Strong diaphragm support |
| C2 | Std | 0 | Stable — good low reference |
| C#2 | Std | 0 to -5 | May tend slightly flat |
| D2 | Std | 0 | Good |
| Eb2 | Std | 0 | Stable |
| E2 | Std | 0 | Good |
| F2 | Std | 0 | Stable reference |
| F#2 | Std | 0 | Good |
| G2 | Std | 0 | Stable |
| Ab2 | Std | 0 | Good |
| A2 | Std | 0 | Good reference pitch |
| Bb2 | Std | 0 | Concert Bb — comfortable range |
| B2 | Std | 0 | Stable |
| C3 | Std | 0 | Good reference — middle of range |
| C#3 | Std | 0 to +5 | May trend slightly sharp |
| D3 | Std | 0 | Stable |
| Eb3 | Std | 0 to +10 | Sharp on many bassoons — voice down; check resonance-key options |
| E3 | Std | 0 to -10 | Often flat and sags on a soft reed — firm air support; a firmer reed or resonance key helps |
| F3 | Open F (whisper key only) | ±5 | The "open F": unstable and often out of tune; add the resonance keys your horn likes (map them against a drone). Tenor register begins; no half-hole on F3 (half-hole starts at F#3) |
| F#3 | Half-hole | 0 to +10 | Half-hole must be precise — F# runs sharp; cover a little more of the hole to lower it |
| G3 | Half-hole | 0 to +10 | Half-hole note — often sharp; cover a little more of the half-hole or voice down; flicking is not used on G3 |
| G#3 | Half-hole | +5 to +10 | Half-hole note — voice down (flicking begins at A3) |
| A3 | Std + flick | +5 to +10 | Flick A key at attack — voice "OH" to lower pitch |
| Bb3 | Thumb Bb + flick (A key) Alt: Trill Bb (bassoons with a Bb trill key) | +5 to +10 | Multiple fingering options — choose for best intonation |
| B3 | Std + flick | +5 to +10 | Flick C key — tenor register peak problem area |
| C4 | Std + flick | +5 to +15 | Flick C key — entering upper register |
| C#4 | Std | +5 to +15 | Voice down, relax embouchure |
| D4 | Std + flick (D key, if fitted) | +10 to +15 | Voice low — "OH" syllable |
| Eb4 | Std | +10 to +15 | Increasing sharpness — relax jaw |
| E4 | Std | +10 to +20 | Very sharp — significant embouchure relaxation |
| F4 | Std | +10 to +20 | Alternate fingerings often better — try several |
| F#4 | LH 2-3 + Eb key | RH 1-2 + low F key (right pinky) Alt: German F#: right-thumb Bb key instead of low F — darker; useful for down-slurs | +10 to +20 | The low-F ("French") F# is the common default; the German Bb-thumb F# is darker — check both against a drone |
| G4 | Std | +15 to +25 | Upper register, not the extreme top (range runs to E5) — sharp-prone; voice down, relax the jaw, map alternates on your horn |
Equipment & Setup
Reeds
- Bassoon reeds are handmade and vary significantly — each reed plays differently
- Wide, open reeds: warmer tone, flatter tendency overall
- Narrow, closed reeds: brighter tone, sharper tendency — better projection
- Cane hardness: softer = flatter, easier response; harder = sharper, more projection
- Reed wires: adjusting first wire (throat) widens/closes opening — directly affects pitch center
- Second wire adjustment: affects response and stability in tenor register
- German vs French cut reeds: German (more common in US) tends slightly darker and flatter
- Reed soaking time: 2-3 minutes minimum — under-soaked reeds are unpredictable
Bocal
- Bocal length and bore critically affect intonation: longer = flatter, shorter = sharper
- Heckel-style bocal letters (C, CC, CD, CE) denote bore and wall design — they change color and response, not length; length, and therefore pitch, is set by the bocal number
- Bocal numbering (1, 2, 3): higher number = longer = flatter — match to your reed tendencies
- Bocal material: silver-plated tends brighter; gold plated warmer and more stable pitch center
- Old/dented bocals significantly degrade intonation — replace or repair if damaged
- Bocal-reed match is critical: try several combinations to find best overall intonation
- Bocal vent hole: must be clean and open — blocked vent degrades upper register pitch
Practice Tips
- Learn multiple fingerings for every note in the tenor and high registers
- Flicking is essential — practice it until automatic for A3, Bb3, B3, C4, and D4
- Reed/bocal combination is the foundation of intonation — experiment with pairings
- Tenor register (F3–B3) requires the most dedicated intonation practice
- Half-hole technique on F#3/G3/Ab3 must be precise — too closed and the note grunts or drops the octave; too open and it turns thin or cracks to the overtone
- Drone-sustain F3, G3, A3, Bb3 (tenor register) — this is where flick keys, half-holes, and reed response combine to drift pitch the most
- Run a mapping pass on your specific bassoon — every horn varies in low Bb (often sharp), middle E (often flat), and high E (highly variable); record cent ranges for each
- Embouchure should be relaxed — biting causes sharpness and tone distortion
- Resonance-key additions are built-in pitch trimmers: keys added below the sounding note (low Eb key, right-thumb keys) subtly raise, lower, or stabilize many tenor-register notes — chart what your horn likes against a drone

- Reed-only crow: full double buzz — 2 min
- F2–Bb2 long tones vs drone, 8 counts — 5 min · drone F2
- Slurred seconds in the bass staff, whisper key steady — 4 min
- F major, one octave, slow — 3 min · 60 BPM
- Rest — 1 min

Flick Keys & Tenor-Register Truth
intermediateCooper & Toplansky’s technical core: flicking A3–D4 for clean attacks, half-hole precision, and the tenor register’s pitch traps. Slow drone-verified passes until the flick is a reflex, not a decision.
- Warm-up: bass-staff long tones — 3 min · drone Bb2
- Flicked attacks on A3/Bb3/C4/D4: 10 clean starts each — 5 min
- Half-hole G#3/G3/F#3: no croak, drone-centered — 4 min
- Tenor-register scale fragments, quarter = 60 — 5 min · 60 BPM
- Rest — 1 min

Tenor Vocalise & Reed-Pitch Interplay
advancedCamden’s musicianship layer: vocal tenor-clef lines (the bassoon’s solo voice) held to string-player pitch standards, with awareness of how today’s reed moves the whole map. Adjust embouchure placement, not bite.
- Warm-up + reed check: crow, then tuning A3 vs drone — 4 min · drone A2
- Tenor vocalise phrase C3–G4, seamless register cross — 5 min
- Messa di voce on D3, G3, C4: pitch pinned vs drone — 5 min · drone G2
- Legato interval study, quarter = 63 — 4 min · 63 BPM
- Rest — 2 min

Ensemble Intonation
Just vs. equal-tempered intervals
How far each pure (just) interval sits from its equal-tempered size.
- Major Third (-14¢ vs. ET): Just major 3rd (5/4) — the most commonly under-adjusted note in ensembles
- Major Sixth (-16¢ vs. ET): Just major 6th (5/3)
- Minor Third (+16¢ vs. ET): Just minor 3rd (6/5) — significantly sharper than ET
- Perfect Fifth (+2¢ vs. ET): Just perfect 5th (3/2) — what bowed strings tune their open fifths to; pianos and frets keep the ET fifth, ~2¢ narrower
Role in the ensemble
- Wind ensemble: oboe gives the tuning A; clarinets and saxes tune to it
- Concert band: tune to a Bb concert (oboe or principal clarinet); brass tunes separately
- In SATB-style wind voicings, the bass instrument (bassoon / contra / baritone sax) holds root
- Major 3rds in woodwind chords are the easiest to over-sharpen — flatten by ~14¢ deliberately
- Whole tones (M2) in close voicings should sit ~+4¢ above ET for a pure 9/8 ratio
Pitch center by genre
- Concert band: A=440
- Orchestra: A=440 (US) / A=442–443 (Europe, Japan many orchestras)
- Jazz/commercial: A=440; tempo and feel often more critical than absolute pitch
- Period/baroque: A=415 (low chamber pitch) or A=430 (Mozart-era classical)
Special cases
- Bassoon is often the bass voice in wind ensemble: upper voices tune their chord tones to its root (the tuning note still comes from the oboe or the band's reference)
- In orchestra, bassoon section tunes to the principal, who tunes to the oboe
- Contrabassoon (octave below bassoon): pitch is unstable; rely on principal bassoon as reference
- Bassoon often shares low-register lines with cellos — match string vibrato width and pitch center
Reed & Mouthpiece
General
- Harder reed = brighter, more resistant, plays slightly sharper at given embouchure pressure
- Softer reed = darker, more responsive, plays slightly flatter; risk of pitch sagging on long notes
- Reed too short / tip over-clipped, or under-scraped (too much cane left): pitch drifts sharp; tone turns thin and resistant
- Reed too long / over-scraped (heart or back thinned too far): pitch drifts flat; response becomes flabby and unstable
- Embouchure pressure (jaw lift / bite): increases pitch; chronic biting causes 10–20¢ sharpness on every note
- Embouchure cushion (flesh-on-reed area): more cushion = warmer, slightly flatter; less = brighter, sharper
- Voicing (oral cavity shape, tongue position): "ee" position raises pitch / brightens; "ah" lowers / darkens
Instrument-specific
- Bassoon reed is the LARGEST woodwind reed — pitch effects of reed changes are correspondingly larger
- Reed wire positions: 1st wire (closest to tip) controls opening + pitch; 2nd wire controls midsection; 3rd wire seals to bocal
- Reed shape (Rieger, German vs French scrape): German tends darker / flatter; French tends brighter / sharper
- Reed wetness affects pitch by 10¢+: too dry = sharp + thin; over-soaked = flat + flabby
- Bocal (crook) length: standard #2 is reference; #1 is shorter (sharper), #3 is longer (flatter); pros own multiple bocals
- Bocal vent (whisper key) interaction: leaks affect octave stability — check periodically
Flick Keys & Half-Hole
- Flick keys (high A, C, D): briefly tap the appropriate flick key when starting upper-register notes to prevent the lower octave from sounding — the flick stabilizes the harmonic, not the pitch directly
- Half-hole on F#3, G3, G#3: the left index finger rolls to partially uncover its tone hole (the left thumb works the whisper and flick keys) — small variation in coverage = significant pitch shift
- Forked Eb / Bb fingerings: use for trills; produce a slightly different pitch center than standard
- Heckel-system vs Buffet-system bassoons have different fingering quirks; the Heckel is dominant in US/UK; Buffet in France
