The Bb clarinet is the most common orchestral and band clarinet, typically written from E3 to C7 and sounding a whole step lower. It is valued for its warm, flexible tone that blends easily in bands and orchestras and can project as a solo voice in classical, jazz, and chamber music.
Overview: The Clarinet Family and Why Bb Dominates
The clarinet family includes a wide range of instruments from the tiny E? clarinet to the massive contrabass clarinet. All share a single reed, cylindrical bore, and similar keywork, but differ in length, pitch, and tone color. Among them, the Bb clarinet dominates school bands, orchestras, and jazz ensembles worldwide.
Historically, the clarinet evolved from the Baroque chalumeau around 1700, with early work by Johann Christoph Denner in Nuremberg. By the early 19th century, improved key systems allowed chromatic playing in multiple keys. As orchestras expanded, Bb and A clarinets became standard, while lower clarinets like bass and contrabass joined in the later 19th and 20th centuries.
Modern clarinets share three main body sections plus mouthpiece and barrel. Longer instruments such as bass and contrabass use a curved neck and upturned bell to keep the size manageable. These anatomical changes, combined with bore diameter and material, create distinct timbres, from bright E? clarinet to dark contrabass clarinet.
Clarinet family snapshot:
Common written ranges: Bb & A clarinets E3-C7, E? clarinet E4-G7, alto clarinet E?3-C7, bass clarinet B?1-E5/F5, contrabass clarinet B?0-C5 (approximate, varies by model).
The Bb clarinet dominates because it balances size, comfort, and versatility. It reads in treble clef, covers a practical written range of about three and a half octaves, and fits comfortably in young players' hands. Publishers, conductors, and band directors typically assume clarinet parts will be played on Bb unless specified otherwise.
Bb Clarinet – Range (E3 to C7), Tone, and Typical Uses
The standard Bb clarinet is a transposing instrument. When you read and play written C, it sounds B? below. Its practical written range for most players runs from low E3 (chalumeau register) up to high C7 (altissimo). Advanced players can extend higher, but E3 to C7 covers almost all band and orchestral parts.
Anatomically, the Bb clarinet has a cylindrical bore, usually around 14.6 to 15.0 mm, with a flared bell and straight body. Student models are often plastic or ABS resin, while professional instruments are typically grenadilla wood. The bore and material contribute to a focused, warm tone that can still cut through an ensemble when needed.
The Bb clarinet's sound changes character across its registers. The chalumeau register (E3-F?4) is dark and woody, the clarion register (G4-C6) is clear and singing, and the altissimo (above C6) is bright and penetrating. Composers like Wolfgang Amadeus Mozart, Johannes Brahms, and Igor Stravinsky exploit these contrasts in solo and orchestral writing.
Key range fact:
Written E3 on Bb clarinet sounds D3. Written C7 sounds B?6. That gives a typical sounding range of about D3 to B?6 for standard orchestral and band repertoire.
In wind bands, Bb clarinets often carry the main melodic line, similar to violins in a string orchestra. In symphony orchestras, they share principal roles with A clarinets, often switching instruments between movements. In jazz, the Bb clarinet is prized for its agility and expressive vibrato, as heard in the playing of Benny Goodman and Artie Shaw.
For students, the Bb clarinet is almost always the first instrument. It matches standard band parts, offers a comfortable hand position, and has a huge library of method books and etudes. Teachers typically recommend starting on Bb and only adding other clarinets once basic embouchure, finger technique, and reading skills are secure.
A Clarinet vs Bb Clarinet – Pitch Relationship and Orchestral Choices
The A clarinet is closely related to the Bb clarinet but is pitched a semitone lower. When you play written C on an A clarinet, it sounds concert A below. The instrument is slightly longer than the Bb, which gives it a subtly darker, more mellow tone that many players favor for Romantic orchestral repertoire.
Written ranges for A and Bb clarinets are essentially identical, from E3 to C7 in most scores. The difference lies in transposition. A clarinet parts are written a minor third higher than sounding pitch, while Bb parts are written a major second higher. This affects key signatures and fingerings but not the physical range of the instrument.
Orchestral composers from Ludwig van Beethoven through Richard Strauss often specify A clarinet for flat keys and Bb for sharp keys. Using both instruments keeps written parts in more comfortable key signatures, which helps with intonation and technical facility. For example, a piece in concert A major is more comfortable on A clarinet than on Bb.
In practice, professional orchestral players own both A and Bb clarinets and switch as required. The A clarinet often appears in symphonies, concertos, and opera, while the Bb clarinet remains standard in wind band, jazz, klezmer, and most chamber music. Students usually add an A clarinet only when they begin serious orchestral playing.
Physically, A clarinets share the same basic bore design and keywork as Bb instruments. Many manufacturers offer matched pairs so that response and feel are similar. This helps players move between instruments with minimal adjustment in embouchure and air support, focusing mainly on transposition and key signatures.
Smaller Soprano Members: C Clarinet and E? Clarinet – Roles and Sound
The C clarinet is a non-transposing soprano clarinet pitched in concert C. When you play written C, it sounds C. Its written range is similar to the Bb clarinet, E3 to C7, but the instrument is shorter and slightly brighter in tone. It was common in early 19th century orchestras but is less used today.
The E? clarinet is a smaller, higher-pitched instrument that sounds a minor third higher than written. Written C on E? clarinet sounds E?. Typical written range extends from E4 to G7, though advanced players may go higher. The shorter tube and smaller bore produce a piercing, brilliant sound that can cut through a full orchestra or wind band.
In orchestras, E? clarinet often plays high, dramatic lines, special effects, or coloristic solos. Composers like Hector Berlioz, Gustav Mahler, and Dmitri Shostakovich use it for shrill, intense climaxes or eerie, distant colors. In wind bands, it often doubles or ornaments flute and piccolo lines, adding brightness to the top of the texture.
C clarinet appears in some classical and early Romantic scores, including works by Franz Schubert and Carl Maria von Weber. Modern performances sometimes transpose these parts for Bb clarinet, but historically informed ensembles may use original C instruments. The C clarinet's direct, clear sound blends well with woodwinds and strings in chamber settings.
Anatomically, both C and E? clarinets use similar keywork to the Bb clarinet but scaled down. Because of the smaller size, hand position can feel cramped, especially on E? clarinet. Many players use a slightly softer reed or a different mouthpiece facing to tame the brightness and improve control in the high register.
Lower Voices: Alto (E?), Bass (B?1 to E5/F5) and Contrabass Clarinet – Ranges and Orchestral Function
The alto clarinet in E? sits between soprano clarinets and bass clarinet. Written C sounds E? a major sixth lower. Its typical written range is E?3 to C7, overlapping much of the Bb clarinet but sounding lower. Alto clarinet appears mostly in wind band and clarinet choir literature, where it fills an inner harmony role.
The bass clarinet in Bb is a key member of modern bands and orchestras. Written C sounds B? an octave plus a major second lower. Most modern bass clarinets have a written range from low E?3 or C3 down to low B?1, and up to written E5 or F5. Some professional models extend higher and lower, but B?1 to E5/F5 is a reliable reference.
Bass clarinet range check:
Common professional bass clarinets: written low C3 to high F5. Student models often start at low E?3. That gives a sounding range from B?1 up to E?5 or F5, depending on design.
Bass clarinets use a larger bore, a curved metal neck, and an upturned metal bell. These features, plus the longer tube, create a dark, resonant tone. In orchestras, composers like Richard Wagner, Claude Debussy, and Olivier Messiaen use bass clarinet for mysterious solos, deep pedal tones, and rich doublings of cellos and bassoons.
Contrabass clarinets extend the family even lower. The most common type is the Bb contrabass clarinet, which sounds two octaves and a major second below written pitch. Written C sounds B? two octaves plus a major second lower. Typical written range runs from low C3 or E?3 down to B?0 and up to around C5, depending on the model.
Contrabass clarinets are usually made of metal or plastic with a complex folded body and large bell. Their tone is deep, organ-like, and somewhat reedy. They appear mainly in wind bands, clarinet choirs, and contemporary or film music, where composers use them for special effects, extreme bass lines, and unique coloristic textures.
In school and community bands, bass clarinet is far more common than alto or contrabass. Directors often move strong Bb clarinet players to bass to balance the ensemble. The transition is manageable because the written parts remain in treble clef and fingerings are closely related, though the feel of the instrument and air support requirements change significantly.
Comparing Ranges and Timbres Across the Family (clear side-by-side summary)
Each clarinet in the family occupies a specific pitch space and timbral niche. Understanding these differences helps players, teachers, and conductors choose the right instrument for each part. The Bb clarinet sits near the center, with higher instruments adding brilliance and lower ones adding depth and weight.
Approximate written ranges and transpositions:
- Bb clarinet: E3 to C7, sounds a major second lower
- A clarinet: E3 to C7, sounds a minor third lower
- C clarinet: E3 to C7, non-transposing
- E? clarinet: E4 to G7, sounds a minor third higher
- Alto clarinet in E?: E?3 to C7, sounds a major sixth lower
- Bass clarinet in Bb: C3 or E?3 down to B?1, up to E5/F5, sounds an octave plus a major second lower
- Contrabass clarinet in Bb: C3 or E?3 down to B?0, up to around C5, sounds two octaves plus a major second lower
Timbre comparisons are just as important as pitch. E? clarinet is bright, penetrating, and sometimes shrill. Bb, A, and C clarinets are versatile and balanced, capable of both warmth and brilliance. Alto and bass clarinets are darker and more velvety, while contrabass clarinet produces a massive, organ-like foundation.
Family spacing:
Each main clarinet type is spaced roughly a perfect fourth to an octave apart in sounding pitch. This spacing allows smooth voicing in clarinet choirs and balanced coverage from soprano to contrabass registers.
Instrument anatomy shapes these timbres. Cylindrical bores favor strong odd harmonics, giving clarinets their characteristic hollow yet focused sound. As the tube length increases, the sound darkens and gains weight. Materials matter too: wood often yields a warmer, more complex tone, while plastic emphasizes clarity and durability.
For arrangers and librarians, a clear overview of ranges avoids unplayable parts. Keeping bass clarinet parts within written E3 to C5 and Bb clarinet parts within E3 to B?6 ensures reliable response for most players. Extreme altissimo or very low extensions should be reserved for advanced performers and clearly marked in the score.
How to Choose the Right Clarinet for Your Ensemble or Repertoire
Choosing the right clarinet starts with the musical context. For school bands, community wind ensembles, and jazz groups, the Bb clarinet is the default choice. It covers most written parts, has the most available repertoire, and offers the easiest access to teachers, method books, and replacement parts.
For orchestral playing, adding an A clarinet becomes important as you advance. Many standard works by Brahms, Tchaikovsky, and Mahler specify A clarinet. Owning both Bb and A allows you to play original parts without awkward transposition and to match the tonal expectations of conductors and colleagues.
C and E? clarinets are more specialized. E? clarinet is important for advanced wind band and orchestral repertoire that calls for it explicitly. C clarinet is useful for period-instrument ensembles or specific classical works but is rarely required in modern school or community settings. Most students can postpone these instruments until later in their studies.
Alto and bass clarinets serve ensemble balance. Directors may assign strong Bb clarinet players to alto or bass to fill out middle and low voices. Bass clarinet is especially valuable in bands and clarinet choirs, where it anchors the harmony and often carries expressive solos. Contrabass clarinet is typically a shared or institutional instrument due to cost and size.
Player level and physical comfort also matter. Younger students usually start on Bb clarinet because of its manageable size and weight. Transitioning to bass clarinet or alto clarinet is easier once hand strength, breath support, and reading skills are established. Teachers should consider hand size, lung capacity, and musical interest when suggesting a move to larger instruments.
For doubling, many advanced players perform on both Bb and bass clarinet, or on Bb and E? clarinet. This increases gig opportunities but requires extra practice to maintain embouchure flexibility, reed setups, and instrument-specific finger habits. Clear planning and consistent warm-ups on each instrument help keep technique balanced.
Care, Maintenance, and Basic Troubleshooting for Clarinet Players
Consistent maintenance keeps the Bb clarinet and its relatives responsive and in tune. Daily care starts with reed selection and rotation. Keep at least 4 to 6 reeds of the same strength in rotation, marking each one. This allows reeds to rest and dry fully between uses, extending their life and stabilizing response.
After every playing session, swab the instrument thoroughly. Remove the mouthpiece and barrel, then pass a clean, lint-free swab through each section from top to bottom. Avoid pulling a wet swab back through the mouthpiece tip, which can chip the facing. Dry the tenons and wipe away moisture from keywork with a soft cloth.
Apply cork grease sparingly to tenon corks whenever joints feel tight, usually a few times per week for active players. Too much grease attracts dirt and can swell corks. Check pads visually for discoloration, fraying, or sticking. Lightly clean tone holes and pad surfaces with a pad cleaning paper if notes start to stick.
Keywork needs periodic attention. A tiny drop of key oil on pivot screws and rods every few months helps prevent binding, but avoid over-oiling. If keys feel sluggish or noisy, or if spring tension seems uneven, consult a qualified technician rather than forcing adjustments. Annual or semiannual professional regulation keeps the mechanism sealing and aligned.
Common troubleshooting starts with squeaks. Frequent causes include a chipped or warped reed, reed placed too high or low on the mouthpiece, biting too hard, or insufficient air support. Check that the reed tip aligns with the mouthpiece tip, the ligature is even, and that you use a steady, supported airstream with relaxed embouchure.
Intonation issues often relate to embouchure, voicing, and instrument setup. Sharp high notes may improve by slightly lowering the tongue position and relaxing the embouchure. Flat low notes can respond to firmer support and checking for leaks around low pads. Testing low B? and altissimo notes is a good way to detect leaks or regulation problems.
Stuck keys or noisy mechanisms usually indicate dried oil, bent rods, or loose screws. Do not force a stuck key. Instead, gently check for obvious obstructions and schedule a repair. Temporary air leaks from minor pad issues may be manageable with careful finger pressure, but long term they require pad replacement or key adjustment.
Field note from the Martin Freres archives:
Early 20th century Martin Freres catalogues show detailed care instructions emphasizing daily swabbing and seasonal checkups, even for simple-system clarinets. Archival repair logs confirm that instruments receiving annual regulation maintained stable intonation and pad sealing far longer than neglected counterparts.
For consistent sound, schedule a professional checkup at least once a year if you play regularly. Technicians can spot worn pads, loose posts, and subtle alignment issues before they cause major problems. Keeping a small kit with swab, cork grease, reed case, and screwdriver for emergency thumb rest adjustments helps you handle minor issues between visits.

FAQ
What is Bb clarinet?
The Bb clarinet is a transposing woodwind instrument that sounds a major second lower than written. Its typical written range is E3 to C7, and it is the most common clarinet used in school bands, wind ensembles, orchestras, and jazz groups because of its versatility and balanced tone.
How does the A clarinet differ from the Bb clarinet?
The A clarinet is slightly longer and pitched a semitone lower than the Bb clarinet, so written C sounds concert A. Both share the same written range, E3 to C7, but the A clarinet has a slightly darker, more mellow tone and is preferred for much Romantic and orchestral repertoire.
What range does a bass clarinet cover?
Most modern bass clarinets in Bb have a written range from low E?3 or C3 down to B?1 and up to E5 or F5, depending on the model. They sound an octave plus a major second lower than written, giving a deep, resonant voice that supports the ensemble's lower register.
When should I use a C or E? clarinet instead of a Bb?
Use E? clarinet when the score specifically calls for it, especially in advanced wind band and orchestral works that need a bright, high soprano voice. C clarinet is mainly used in classical and early Romantic repertoire or period-instrument ensembles. For most modern band and orchestra parts, Bb clarinet remains the default.
How do I maintain my clarinet to keep the sound consistent?
Swab the instrument after every use, rotate 4 to 6 reeds, apply cork grease when joints feel tight, and check pads and keywork regularly. Schedule a professional regulation at least once a year. Consistent daily care and periodic technician visits help keep tone, response, and intonation stable.
Can one player double on Bb and bass clarinet in an orchestra?
Yes, many players double on Bb and bass clarinet in orchestras and wind ensembles. The fingerings are closely related, and parts are written in treble clef. However, doubling requires practice to adjust embouchure, air support, and reed setups, so players should plan warm-ups and equipment choices for each instrument.
