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 improves upper register response and pitch
Half-hole technique affects pitch
Temperature affects wooden body significantly

🌡️ Temperature & Warm-up

Wooden body responds slowly to temperature. Allow to acclimate before playing.

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–Bb3): The most challenging for bassoon intonation. Flicking (briefly touching the A/C/D thumb keys at the attack of each note) dramatically improves response and pitch accuracy. Half-hole technique on F3 and F#3 must be precise. Without flicking, notes tend to "sag" or crack.

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 highest notes (F4+) require specialized practice and instrument-specific fingerings.

F3	Std/Half-hole	±5	Tenor register begins — half-hole technique critical

Bb3	Thumb Bb Alt: Trill Bb (slightly different pitch) · Long Bb (some instruments)	+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 D key — entering upper register
C#4	Std	+5 to +15	Voice down, relax embouchure
D4	Std (thumb)	+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	Alt	+10 to +20	Alternate fingerings often better — try several
F#4	Alt	+10 to +20	Multiple fingerings available — find best for your instrument
G4	Alt	+15 to +25	Extreme high range — specialized fingerings required

🔧 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
CC (short) bocal: higher pitch center, brighter; CCD: slightly longer, lower pitch center
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 G3, A3, B3, C4
Reed/bocal combination is the foundation of intonation — experiment with pairings
Tenor register (F3–Bb3) requires the most dedicated intonation practice
Half-hole technique on F3/F#3 must be precise — too open = flat, too closed = sharp
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

Section Role

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

Genre Pitch Center

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)

Overrides

Bassoon is often the bass voice in wind ensemble; others tune to it (not the reverse)
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 / overcut: pitch drifts sharp; tone center becomes thin
Reed too long / undercut: pitch drifts flat; response becomes sluggish
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

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: left thumb partially covers the F# hole — 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
