The Whole Horn
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 tuba is written in bass clef, and the range you will find in a scored part runs from D1 to F4 — about 3.2 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 tuba reads at concert pitch, so the written range and the sounding range are the same notes: D1 to F4 either way. There is nothing to convert.
That is worth stating plainly because it is the question people actually ask. On a transposing instrument the two ranges are different and both get quoted, which is why range figures found in different places so often disagree by a whole interval. Here they cannot.
| Note | Written | Sounds |
|---|---|---|
| Lowest scored note | D1 | D1 |
| Highest scored note | F4 | F4 |
| Lowest learner-comfortable note | G1 | G1 |
| Highest learner-comfortable note | C4 | C4 |
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 G1 to C4 as the learner-comfortable written compass of the tuba.
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 C4 today is not outside the range; they are on their way to it.
The highest note commonly written for the tuba is F4. 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 scored range assumes a four-valve instrument. The gap below the bottom of a three-valve tuba's ordinary compass is exactly what the fourth valve exists to fill, so a written low range that one player has and another does not is a question about the instrument, not the player. Below all of it lies the pedal register, which on a tuba is genuinely subterranean and genuinely useful.
The scored range — written D1 to F4 — 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 G1 to C4 — 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 tuba is D1 to F4, about 3.2 octaves, written and sounding the same because the instrument reads at concert pitch.
The highest note commonly written for the tuba is F4. 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 D1. The Whole Horn treats G1 as the lowest learner-comfortable written note.
The Whole Horn's learner-comfortable written range for the tuba is G1 to C4. 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.
Yes. The tuba reads at concert pitch, so D1 to F4 is both the written and the sounding range.
About 3.2 octaves in the standard written range, from D1 to F4. The learner-comfortable span is narrower, from G1 to C4.
The Whole Horn plays all twelve major scales in the tuba's own written pitch and bass clef, so what you read is what you play.
