What is the range of the clarinet?

Quick answer. The standard written range of the clarinet is E3 to C7 — 3.7 octaves on the page. Because the clarinet in B♭ · sounds a major second lower, those notes sound as concert D3 to B♭6. The range a school player actually lives in is narrower: E3 to C6 written. The highest note commonly written is C7.

Both bars are written pitch, on one scale. The lower bar is the compass The Whole Horn treats as learner-comfortable — a range, not a fence.

The written range

The clarinet is written in treble clef, and the range you will find in a scored part runs from E3 to C7 — about 3.7 octaves. This is the figure orchestration texts publish and the one a composer writes inside. It is the answer to “what can I put on the page for this instrument”.

The sounding range

The clarinet is a B♭ instrument: it sounds a major second lower. Every note in the written range moves by that same interval, so the sounding range is the written range shifted whole — concert D3 to B♭6. Nothing is compressed or stretched; a range is transposed exactly the way a single note is.

This is the figure that matters when a composer is checking whether a line fits, or a director is working out why the clarinet cannot play the part in front of it. The written range answers “can I read this”; the sounding range answers “will this be the pitch I wanted”.

The range a school player actually lives in

The scored range and the range a developing player owns are not the same thing, and pretending otherwise is how a part ends up unplayable by the section it was written for. The Whole Horn treats E3 to C6 as the learner-comfortable written compass of the clarinet, sounding concert D3 to B♭5.

That is a range, not a fence. It is where a developing player is secure enough that the note is not the hard part — not a boundary the instrument enforces and not a limit anyone should be told they have. Both ends move outward with practice, at different rates, and they move for different reasons at the top than at the bottom. A student who cannot reach C6 today is not outside the range; they are on their way to it.

The highest note commonly written — and what moves it

The highest note commonly written for the clarinet is C7, which sounds concert B♭6. That is the top of the scored range, which is a publishing convention rather than a measurement: it is the note above which a composer stops being able to assume the player has it.

The clarinet overblows at the twelfth, not the octave, which is why its written range is so wide and why the fingering pattern restarts where it does. The scored top of C7 belongs to the altissimo register, above the register key's reach, and it is genuinely hard; the ceiling that matters to a student is much lower and moves as the throat tones and the break come under control.

Where these figures come from

The scored range — written E3 to C7 — is the figure this site already publishes on the band transposition chart, and the two pages read it from one table so they cannot disagree. It is the standard range these instruments are taught and scored in.

The learner-comfortable range — written E3 to C6 — is The Whole Horn's own instrument table, the one the app itself reads. Its header states the contract: lo/hi = WRITTEN MIDI, learner-comfortable. It is a published in-house figure with a stated philosophy, not an estimate written to fill a paragraph.

The sounding range is derived here from the written range by interval, not stored — a stored second copy is a copy that can disagree with the first.

The lowest note in the standard written range is E3, sounding concert D3. The Whole Horn treats E3 as the lowest learner-comfortable written note.

What range can a school clarinet player actually play?

Is the clarinet's written range the same as its sounding range?

No. The clarinet in B♭ · sounds a major second lower, so the written range E3 to C7 sounds as concert D3 to B♭6.

How many octaves does the clarinet have?

About 3.7 octaves in the standard written range, from E3 to C7. The learner-comfortable span is narrower, from E3 to C6.
