Bassoon
The bassoon has complex fingerings with many options for the same note. Reed and bocal selection significantly affect intonation.
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.
Note-by-Note Tendencies
| Note | Fingering / Position | Tendency | Adjustment |
|---|---|---|---|
| Bb1 | Low Bb (all keys) | -5 to -15 | Maximum support, open throat, warm air column |
| 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 Ab — 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 | Good |
| E3 | Std | 0 to +5 | Approaching tenor register |
| F3 | Std/Half-hole | ±5 | Tenor register begins — half-hole technique critical |
| F#3 | Half-hole | ±5 to +5 | Half-hole must be precise |
| G3 | Std | ±5 to +10 | Tenor register — flick A key at attack for clean response |
| G#3 | Std | +5 to +10 | Flick key helps — voice down |
| A3 | Std + flick | +5 to +10 | Flick A key at attack — voice "OH" to lower pitch |
| 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
