How to Choose Clarinet Reeds: Strength, Cut and Brand
A practical guide to picking the right clarinet reed strength, understanding cuts and brands, breaking reeds in and making them last.
Updated · Tonehole editors
The reed is the part of your setup you will change most often, and it has more effect on your sound than almost anything else you can buy. The good news: choosing well is not a mystery. It comes down to three questions — how hard, what cut, and does it suit my mouthpiece.
Reed strength: what the numbers mean#
Reeds are graded by stiffness, usually on a scale from about 1.5 (soft) to 5 (hard), often in half or quarter steps.
| Strength | Typical player | What it feels like |
|---|---|---|
| 1.5–2 | First months of playing | Speaks with very little air; bright, can sound thin and goes flat when pushed |
| 2.5 | Most beginners after a few months | Easy response with a fuller core |
| 3 | Intermediate and many advanced players | The common middle ground on medium mouthpieces |
| 3.5–4 | Advanced and professional players | Dark, stable, needs well-developed air support |
| 4.5–5 | Specialists, very close mouthpieces | Very resistant |
The numbers are not standardised between brands. A "3" from one maker can feel like a 2½ or a 3½ from another, and different lines from the same company are cut differently. Treat the number as a starting point and use the manufacturers' own comparison charts when you switch.
Signs your reed is too soft#
- The sound is buzzy or thin, especially in the clarion and altissimo.
- High notes go flat and the pitch sags when you play loudly.
- The reed "closes up" (chokes) when you push more air.
Signs your reed is too hard#
- Low notes are slow to start and you need to bite to get a sound.
- The tone is airy or stuffy and you tire quickly.
- Soft entrances are difficult.
Reed and mouthpiece belong together#
The right strength depends on your mouthpiece tip opening. A more open mouthpiece (bigger gap between reed and tip) generally needs a softer reed; a closer mouthpiece suits a harder one. That is why two players with similar skill can happily use 2½ and 3½ reeds. If you change mouthpiece, expect to re-test reed strengths. See our mouthpiece guide.
Cut and vamp#
The vamp is the thinned, tapered part of the reed. Its shape and thickness profile determine how the reed vibrates:
- Filed ("French file") reeds have a strip of bark removed just behind the vamp. They tend to respond quickly and sound a little brighter. Almost all classical clarinet reeds are filed.
- Thicker tip and heart cuts give a darker, more focused sound and more resistance at the same nominal strength.
- Thinner tips speak easily and articulate lightly but can sound bright.
Cane reeds are a natural product — two reeds from the same box will never be identical.
Synthetic reeds#
Synthetic (polymer) reeds are consistent from one to the next, need no wetting and last for months. They are excellent for outdoor playing, doubling and anyone who wants reliability. Many players find they need a synthetic reed about a quarter to half a strength softer than their cane reed.
Breaking in new cane reeds#
New reeds change quickly in the first days. A gentle break-in makes them more stable and longer-lasting:
- Day 1–2: soak briefly in water, then play only two or three minutes of long tones and simple scales.
- Day 3–4: five to ten minutes, still avoiding loud playing and extreme registers.
- From day 5: normal use. Retire reeds that never settle.
Keep a rotation#
Use four to six reeds in rotation rather than playing one until it dies. Number them on the bark, play each in turn, and note which ones are best for concerts. Store them flat in a ventilated reed case and always rinse off saliva after playing.
When to throw a reed away#
- Chips or cracks on the tip.
- The sound has become dull and fuzzy and no longer recovers.
- It has warped and will not seal on the mouthpiece table.
What strength reed should a beginner clarinettist use?#
Most beginners start on a 2 or 2½ on a standard student mouthpiece and move to 2½–3 within the first year as air support develops. Teachers usually move students up half a strength when the current reed starts to sound thin and close up.
Why do my reeds squeak?#
Squeaks are usually caused by too much mouthpiece in the mouth, biting, a hole not fully covered, or a damaged or warped reed. Check the reed tip for chips and make sure it is centred on the mouthpiece before blaming the strength.
How long does a clarinet reed last?#
With a rotation of four to six reeds and daily practice, a good cane reed typically lasts two to six weeks. Synthetic reeds usually last several months.
