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 french horn is written in treble clef, and the range you will find in a scored part runs from F♯2 to C6 — about 3.5 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 french horn is a F instrument: it sounds a fifth lower. Every note in the written range moves by that same interval, so the sounding range is the written range shifted whole — concert B1 to F5. 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 french horn 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”.
| Note | Written | Sounds |
|---|---|---|
| Lowest scored note | F♯2 | B1 |
| Highest scored note | C6 | F5 |
| Lowest learner-comfortable note | F3 | B♭2 |
| Highest learner-comfortable note | C6 | F5 |
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 F3 to C6 as the learner-comfortable written compass of the french horn, sounding concert B♭2 to F5.
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 for the french horn is C6, which sounds concert F5. 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 horn's written compass is wide — nearly four octaves on paper — and no player owns all of it equally. High up, the harmonic series partials sit a step or less apart, so neighbouring notes share a fingering and are separated only by the player's air and embouchure. That is the whole reason the horn has a reputation for cracked notes, and it is why the practical top of a school horn part sits far below the scored ceiling.
The scored range — written F♯2 to C6 — 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 F3 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 standard written range of the french horn is F♯2 to C6, about 3.5 octaves. Those written notes sound as concert B1 to F5.
The highest note commonly written for the french horn is C6, which sounds concert F5. That is the top of the range parts are scored in. It is not a physical limit — see what moves that ceiling below.
The lowest note in the standard written range is F♯2, sounding concert B1. The Whole Horn treats F3 as the lowest learner-comfortable written note.
The Whole Horn's learner-comfortable written range for the french horn is F3 to C6, sounding concert B♭2 to F5. That is where a developing player is secure, not a fence — the ends move outward with practice, and they move at different rates for different players.
No. The french horn in F · sounds a fifth lower, so the written range F♯2 to C6 sounds as concert B1 to F5.
About 3.5 octaves in the standard written range, from F♯2 to C6. The learner-comfortable span is narrower, from F3 to C6.
The Whole Horn plays all twelve major scales in the french horn's own written pitch and treble clef, so what you read is what you play.
