Clarinet and saxophone reeds: what strength should you choose?
A 2½ isn't the same across brands, and a harder reed isn't a better one. How to read reed strength, what the cut changes and when to move up or down.
A reed's strength indicates how much resistance it offers when vibrating: lower numbers (1½, 2) are softer and respond with little air; higher numbers (3½, 4 or more) are harder and require more air and more embouchure control. Most clarinet and saxophone beginners start between 1½ and 2½, moving up in half-point increments when their sound calls for it, rather than after a set amount of time.
The catch is that the number isn't universal: each manufacturer measures strength differently, and even within one box some reeds are harder than others. So rather than looking for “the right number,” you're looking for a reed that works with your mouthpiece and embouchure.
In short
- Strength is a general scale, usually from 1 to 5 in half-point steps, but it varies between manufacturers and even between product lines from the same maker.
- Harder isn't better: the right reed responds across the full range without making you bite or strain.
- The mouthpiece matters most: a very open mouthpiece usually calls for softer reeds, and a closed one for harder reeds.
- Go up half a point if the reed closes up on high notes, plays flat or buzzes; go down if you tire quickly and low notes won't speak.
- A filed reed often feels more responsive and brighter than an unfiled reed of the same strength.
What the strength number means
The number indicates the reed's stiffness: how much air and lip pressure it needs to start vibrating. A soft reed responds to little air and is easy to get a sound from, but closes up easily. A hard reed offers more resistance and needs faster air and a firmer embouchure; in return, it supports the sound better at high volume or in the upper register.
| Number | How it feels | Who typically uses it |
|---|---|---|
| 1½ to 2 | Very soft: responds with little air | First weeks, children and players whose embouchure is still developing |
| 2½ to 3 | Medium: balances response and control | Many students after the first few months |
| 3½ to 4 or more | Hard: requires fast air and a firm embouchure | Advanced players whose mouthpiece calls for it |
- There is no universal scale. One manufacturer's 2½ may feel like another's 3, and two lines from the same manufacturer may not match.
- Other labeling systems exist. Some use words (soft, medium, hard), quarter-point steps or symbols such as “+”. The comparison charts you'll find are approximate.
- Synthetic reeds have their own scale. Don't assume a synthetic reed feels the same as a cane reed with the same number.
- Reeds vary within a box. That's why you test and sort them, as you'll see below.
The mouthpiece also matters
The same reed behaves differently depending on the mouthpiece. The biggest factors are the tip opening—the gap between the reed tip and mouthpiece tip—and the length of the facing curve against which the reed rests.
| More closed mouthpiece | More open mouthpiece | |
|---|---|---|
| Reed it typically needs | Harder | Softer |
| Feel | More control and resistance, less air | More air and volume, more flexibility |
| If the reed is unsuitable | With a soft reed, the sound chokes and plays flat | With a hard reed, sound is difficult to produce and your mouth tires quickly |
That's why “What strength do you use?” doesn't tell you much without knowing the mouthpiece, and why changing mouthpieces means trying strengths again. Also remember that clarinet, alto saxophone and tenor saxophone reeds come in different sizes and aren't interchangeable; we explain this in choosing your first saxophone and choosing your first clarinet.
Cuts: filed, unfiled and other details
Two reeds with the same strength number can feel very different because of their cut. It helps to know their parts: the heel, the thick, bark-covered area held by the ligature; the vamp, the pale, scraped area that vibrates; the heart, the thicker center of the vamp; and the tip, the thinnest edge, which aligns with the mouthpiece tip.
| Cut | How to recognize it | What usually changes |
|---|---|---|
| Unfiled | The bark ends in a U shape where the vamp begins | More resistance and body; a darker sound and slightly slower response |
| Filed (or French cut) | A narrow strip of exposed cane just before the vamp | Faster response and brighter sound; feels somewhat softer than an unfiled reed of the same strength |
| Vamp length and tip thickness | Described by the manufacturer rather than easily seen at a glance | They change response and tone color; these are refinements for when you already have a stable sound |
Filed reeds are very common on clarinet; saxophone reeds come in both types, with some lines marketed for classical music and others for jazz or popular music. Their cut and thickness differ, so the number alone doesn't tell you how they'll feel.
Is your reed too hard or too soft?
| Sign | Reed too hard | Reed too soft |
|---|---|---|
| Sound | Breathy, with excess air noise and little focus | Buzzy, spread or nasal, with little body |
| Low notes | Hard to produce, or start with a harsh attack | Speak easily, but spread when you play loudly |
| High notes | Speak, but take a lot of effort | Choke, stop sounding or play flat |
| Tuning | Tends to play sharp, especially if you bite | Tends to play flat, especially in the upper register |
| Fatigue | Your mouth tires within minutes | Hardly tiring, but the reed doesn't support you when playing loudly |
Before blaming the reed, rule out other issues: a warped reed or one misaligned with the mouthpiece tip, a ligature that's too loose or too tight, a chipped mouthpiece or leaking pads. A new reed won't fix any of those.
When to move up (or down) in strength
Moving to a stronger reed isn't a promotion to a higher level. Many professional musicians use medium strengths because what matters is that the reed works with their mouthpiece and the sound they want. Here are signs it may be time to move up:
- High notes choke or go flat even with good breath support.
- When you play loudly, the sound spreads and loses focus.
- New reeds from your box feel soft from the first day.
- Your teacher notices that your embouchure can now support more than the reed can handle.
Signs to move down include tiring within minutes, low notes that won't speak, a breathy sound or starting to bite the mouthpiece. To make the change:
- Move up or down half a point, rather than a full point.
- Buy a few reeds in the new strength and alternate them with your previous ones for a few weeks.
- Bring both to your lesson and play the same passage on each for your teacher.
- If the new reed still tires you after a reasonable time, return to the previous one: the right strength is the one that lets you play better today.
How to test and sort a new box
- Number each reed in pencil on the bark at the heel, and note the date.
- Hold it up to the light: the darker area of the heart should be centered, and the vamp even on both sides. An asymmetrical reed often responds less well.
- Moisten it and play it for only a few minutes on the first day; add a little time each day during the first week.
- Note how each one feels: good response, dull sound, hard or soft.
- Sort them: the best for rehearsals and performances; the acceptable ones for practice; those that don't work for exercises or disposal.
Some reeds can be adjusted: very fine sandpaper on the vamp softens them, and trimming a tiny bit from the tip with a reed clipper makes them harder. Learn these techniques with your teacher, because it's easy to go too far and ruin a salvageable reed.

Climate and reeds: Bogotá versus warmer regions
Cane reeds respond to humidity. Many musicians notice that in Bogotá's cold, dry climate, reeds dry quickly while they play and feel stiffer, while in hot, humid regions they soften sooner and warp if not dried properly.
- If you travel to play in a different climate, bring reeds in your usual strength and a few half a point above or below it.
- Always moisten it before playing; in a dry climate it may need a few extra seconds.
- Don't leave it in the sun or inside a car: heat warps it.
Over time, you'll learn to understand your own reeds. Meanwhile, the most efficient approach is to test them with someone listening: in clarinet and saxophone lessons, choosing a reed is part of the first few weeks' work.
Frequently asked questions
What reed strength should I use as a beginner?
Most beginners start between 1½ and 2½, depending on the manufacturer and mouthpiece. If it's very hard to produce a sound, try a half-point softer; if the sound is too open and flat, try a half-point harder.
Can I use the same strength on clarinet and saxophone?
The number may be similar, but the reeds aren't interchangeable and the feel changes with each mouthpiece. If you play both instruments, choose the strength for each separately.
How long does a reed last?
It depends on how much you play, how you store it and the reed itself. With rotation and proper drying, a reed used daily often lasts a few weeks. When it loses brightness, chokes on high notes or develops spots, it's time to replace it.
Are synthetic reeds suitable for beginners?
They can be: they last longer, are more consistent and don't need moistening. They feel different from cane reeds and their strength scales aren't equivalent, so try them with your teacher before switching completely.
