The phrase clarinet type instruments covers a family of single‑reed, cylindrical‑bore woodwinds that span tiny sopranino pitches to room‑shaking contrabass registers; understanding that family explains which instrument a score calls for, how written notes translate to sounding pitch, and why players switch instruments for tone and range.
How the clarinet family is organized: voices, pitch centers and why transposition matters
Clarinet voices form a tree: high sopranino and piccolo at the top; soprano clarinets (B♭, A, C, E♭) as the core; middle voices like the basset horn (F) and alto (E♭); then bass and contrabass at the bottom.
“In B‑flat,” “in A” and “in E‑flat” name instruments by their written-to-sounding pitch relationship: a B♭ clarinet sounds a whole step lower than written; an A sounds a minor third lower; an E♭ sounds a minor third higher for soprano E♭ or a major sixth higher for alto E♭ depending on octave notation.
Orchestras request A or B♭ clarinets because composers write in keys that lie easier on one instrument, improving intonation and timbre in exposed passages; bands prefer B♭ for blending and projection; clarinet choirs routinely use the full set of voices.
Soprano clarinets — B-flat, A, C and E-flat: tone colors, repertoire and when to switch
The B♭ soprano is brighter and projects more in band and jazz settings; the A clarinet usually sounds warmer and sits better in orchestral keys like A major and F major, which is why Mozart and Brahms often specify A.
The C clarinet appears in Classical and early 20th‑century scores for a natural, non‑transposing option; the E♭ soprano is smaller, piercing, and common in bands and contemporary works for its cutting, piccolo‑like color.
Switching between A and B♭: keep fingerings identical, adjust reed strength and mouthpiece facing (slightly thinner facing or weaker reed on A for more resonance), and listen for the instrument’s center pitches—tune with tuner and a fixed pitch reference before rehearsal.
Miniature and high voices: sopranino and piccolo clarinets in specialized music
Sopranino and piccolo clarinets extend upward beyond the E♭ soprano, adding a sharp, bright top that clarinet choirs and contemporary composers use for textural sparkle.
Tuning sits higher and requires tighter embouchure; these instruments transpose like their soprano cousins, so check written versus sounding pitch and carry a targeted reed set with narrower tips to ease altissimo response.
Expect limited repertoire; teachers typically assign these only for specific ensemble pieces or modern works that call for that bitey high register.
Basset horn and basset clarinet: the lower soprano with extended low range and unique repertoire
The basset horn in F sits between soprano and alto, with an extended chalumeau (low) register that Mozart used for darker colors in clarinet‑centered works; the basset clarinet is essentially an A clarinet with extra low A–C notes.
Extra low notes add keys and alternate fingerings; editions that use these pitches require true basset instruments or modern reconstructions—playing those parts on a standard clarinet forces octave transposition or compromises.
For a full, mellow bottom end use a mouthpiece with a slightly larger chamber and a reed one strength firmer than your soprano setup to stabilize low resonance.
Alto clarinet: its role in wind bands and why it’s less common in orchestras
The alto clarinet in E♭ doubles inner harmony in wind bands and clarinet choirs but fell out of favor in orchestras because its timbre often conflicts with standard orchestral balances and parts are sparse.
Its range sits below the basset horn but above the bass clarinet; the sound blends well in homogeneous wind textures but offers less projection for solo orchestral lines.
Consider an alto only if you play in wind ensembles or clarinet choirs; test for even tone across chalumeau and clarion registers and confirm reliable pad sealing on low keys before buying.
Bass clarinet: the big-voice low clarinet for orchestras, chamber and jazz
The bass clarinet commonly sounds an octave below the B♭ soprano (written a major ninth) and provides both foundational bass and solo color in orchestral scores by Debussy, Ravel and many modern composers.
Technical demands include alternate low‑register fingerings, vented keys for clearer upper register, and a physically larger mouthpiece and stronger reeds to generate a full low sound without choking the harmonics.
Use ligature tension and reed strength to balance response; players often choose a heavier reed and larger tip opening than on soprano clarinets to maintain depth and flexibility.
Contrabass and other ultra-low clarinets: orchestral impact and contemporary exploration
Contrabass clarinets (B♭ and E♭ variants) extend the family downward by another octave or so, producing sub‑octave color that composers exploit for weighty, atmospheric effects in modern scores and clarinet choirs.
These instruments are large, heavy and require specialized keywork; plan logistics: transport cases, stand support and warmed rehearsal rooms to avoid sluggish response and tuning instability.
Repertoire is limited but impactful; contemporary composers write sustained, extended techniques and microtonal effects that only contrabass instruments can deliver, so hire one only if you need that color.
Historical ancestors and global relatives: chalumeau, folk clarinets and single‑reed traditions
The chalumeau is the clarinet’s direct ancestor with a limited low range and simple keywork; its tone shaped early classical writing and evolved into modern clarinet key systems and bore designs.
Regional clarinet traditions—klezmer, Balkan/Turkish, choro—use different fingerings, ornamentation and reeds; those instruments often have conical bores or different mouthpiece geometries and do not substitute directly for orchestral clarinets.
When arranging or teaching folk repertoire respect the original instrument’s tuning and stylistic articulation rather than forcing standard clarinet fingerings onto incompatible parts.
How clarinet acoustics and registers define type differences: chalumeau, clarion and altissimo explained
Clarinet registers split into three working zones: chalumeau (rich low notes), clarion (clear middle voice), and altissimo (piercing high notes); each instrument emphasizes these regions differently based on length and bore.
Because clarinets have a cylindrical bore they overblow at the twelfth, not the octave; that physical fact dictates fingerings and register transitions and causes the middle register to sit uniquely compared with flutes and saxophones.
Practically, shape your air and voicing to smooth chalumeau-to-clarion breaks and use targeted altissimo exercises when switching to smaller sopraninos or larger bass instruments.
Mouthpieces, reeds and ligatures: setup choices that shape sound across clarinet types
Mouthpiece chamber and tip opening control brightness and ease: narrow openings and small chambers favor focused classical tone; wider openings and larger chambers favor jazz projection and fuller low end on bass instruments.
Cane reeds offer complex harmonics; synthetic reeds increase weather stability—choose reed strength one to two steps firmer on larger bores and slightly lighter on high sopranino instruments for articulation control.
Ligature material alters attack and freedom: metal and fabric give brighter or darker responses respectively; test ligatures on the specific instrument to judge articulation clarity and resonance.
Materials and construction: grenadilla, plastic, ebonite and metal clarinets — tone versus durability
Grenadilla (African blackwood) remains the professional standard for focused tone and stable resonance; plastic and resin bodies suit students and humid climates for durability and price point.
Ebonite and metal clarinets offer distinct colors—ebonite warms the sound; metal produces brightness and projection—but keywork and bore precision matter more than body material at pro levels.
For touring, choose materials and instrument setups that resist cracking and hold intonation; consider backup instruments and temperature‑controlled cases as routine insurance.
Reading parts and practical transposition tips for players switching instruments
To transpose quickly: for B♭ instruments sound a major second lower than written; for A sound a minor third lower; for E♭ soprano sound a minor third higher—think interval shift, not accidental rewriting of every note.
For bass and contrabass watch octave indications: many parts are written sounding an octave and a ninth; always confirm clef and any ledger lines before playing, and mark transposition on score staves to avoid mistakes.
Audition prep: practice exposed orchestral excerpts in both A and B♭, and run intonation checks on open strings or oboe reference pitches to anchor tuning quickly at auditions.
Buying and renting: choosing the right clarinet for students, advancing players and pros
Match instrument to goals: student plastic B♭ for school bands; intermediate grenadilla with better pads for advancing players; professional factory‑handmade grenadilla with refined bore for orchestral soloists.
Key buying checklist: consistent tone across registers, smooth key action, pads sealing low keys, no cracks in the wood, and acceptable setup of thumb rest and bell alignment.
Rent when short on budget or unsure of long‑term commitment; rent‑to‑buy options let you trial a model for repertoire needs before committing to a professional instrument purchase.
Maintenance, common repairs and realistic service expectations
Daily care: swab after playing, remove moisture from pads, grease corks weekly, and store in a case upright to avoid warping; seasonal service should include pad checks and key regulation.
Common repairs include pad replacement, spring adjustment, cork repair and crack stabilization; expect turnaround from a competent tech of a few days to two weeks and budget accordingly—pads and major adjustments cost more than simple cork fixes.
Spot poor setups by uneven intonation, sticky pads or rattling keys; a well‑set instrument plays evenly across registers and responds with predictable resistance.
Doubling and pedagogy: learning to move between clarinet types or double on sax/other reeds
Progress students by securing a stable soprano technique first, then introduce differences incrementally: embouchure tightening for sopranino, relaxed aperture and heavier air for bass, and incremental repertoire to build confidence.
When doubling on saxophone expect different mouthpiece angles, reed widths and voicing; assign dedicated exercises to separate articulation habits and to maintain tone quality on both instruments.
Schedule lesson goals for gradual adaptation: two weeks focused on scale sets, two weeks on orchestral excerpts, and regular recorded review to monitor tone and intonation shifts while doubling.
Genre-focused picks: which clarinet type to choose for jazz, classical, chamber, wind band and folk
Jazz: choose B♭ soprano with medium‑large tip opening, darker mouthpiece chamber and a firm reed for projection and flexible attack.
Classical/orchestral: carry A and B♭ soprano pairs; use A for Mozart and late‑Romantic repertoire and B♭ for band work and modern pieces needing brighter projection.
Clarinet choir and chamber: stock sopranino, E♭, A/B♭ soprano, basset horn, alto, bass and contrabass to cover full harmonic spectrum; balance reed strengths to blend.
Folk styles: match instrument and reed to tradition—Turkish and Balkan players use different bore shapes and ornamentation; learn authentic articulations rather than forcing classical technique.
Famous recordings, composers and solo works that spotlight specific clarinet types
Mozart’s Clarinet Concerto and Quintet exemplify A clarinet’s warmth and are essential references for phrasing and tone on A instruments.
Debussy’s orchestral palette gives bass clarinet featured solos; Ravel and Stravinsky use extended low clarinet color—listen to their scores to understand orchestral balance.
Jazz: Benny Goodman recordings define B♭ jazz tone and articulation; modern improvisers show extended techniques and alternate mouthpiece setups that shape contemporary clarinet sound.
