There is nothing to adjust
Every other instrument on this site has something you can turn, slide, or tap. An ocarina has none of it. It is a closed clay vessel with holes in it, and its pitches were set by the maker while the clay was soft and locked in permanently when it was fired.
So “how do I tune an ocarina” has an unusual answer: you do not. What you can change is breath— and on this instrument breath moves pitch further than on almost anything else, which means a tuner is genuinely useful here, just not for the reason it usually is. It is not a repair tool. It is how you find out whether a note that sounds wrong is the instrument’s fault or yours.
The first tab is a standard alto C scale. The second picks three points across the range so you can hear how far apart the extremes are — those three notes need very different amounts of air.
The breath curve
This is the central concept, and it is the thing most ocarina beginners are never told.
On an ocarina, each note needs a different amount of air. The lowest notes speak on almost nothing; every note above needs progressively more; the top of the range needs the most by a wide margin. Playing in tune therefore means continuously increasing pressure as you ascend and easing it as you come back down. That is not a defect to work around — it is how a vessel flute produces pitch, and learning to do it smoothly is most of what learning the ocarina consists of.
Which gives you a diagnostic that works on any instrument you pick up:
- Play up the scale slowly with the tuner running, blowing only as hard as each note needs to speak cleanly — not harder.
- Note the pitch of each note at that minimum pressure.
- Note how the required pressure changes as you climb.
On a well-made ocarina the pressure requirement rises smoothly and each note lands close to correct at its own natural pressure. Two results point at the instrument instead: notes that read sharp even at the least air that will sound them, and a stretch of the range where the pressure requirement does not increase at all. Neither can be fixed by playing better.
Using the dial to practise, not to fix
Because the instrument cannot be corrected, the tuner’s real job here is training your breath. This is a different way of using one and it works well:
- Hold a single note and watch the needle drift. If it climbs as the note continues, you are pushing harder as you run out of air — extremely common, and visible on a display long before it is audible to you.
- Play slow scales and watch where the pitch dips or spikes. Those are the places your pressure changes in steps rather than smoothly.
- Play an interval leap and check the arrival note. Jumping from a low note to a high one requires a large, immediate pressure change, and undershooting it is why big leaps come out flat.
Which ocarina you have
The common modern instrument is the 12-hole alto C, with a range of about an octave and a fifth, and all holes covered sounding its lowest C. Sopranos and basses exist and play the same fingerings an octave apart. Other keys — G, F — are made too.
There is a quick way to identify an unmarked instrument: cover every hole, blow gently, and read what the display says. That note is the bottom of the instrument’s range and names its key. If the reading is not a clean note at all, one of the holes is not fully sealed by your fingers, which on a 12-hole instrument is easily done and is worth ruling out before you blame the ocarina.
What the needle can and cannot settle
The dial measures pitch against a fixed reference, and on an instrument with no adjustment that turns it into a measuring device rather than a setup one. It answers two questions precisely: is this note where it should be at a sensible breath pressure, and is my breath steady enough to keep it there.
What it cannot tell you is whether an instrument is worth keeping. An ocarina that reads a few cents sharp at the top of its range but has a smooth breath curve is a perfectly good instrument that you learn to play; one that reads perfectly but requires an abrupt jump in pressure between two adjacent notes is more annoying to play than the numbers suggest. Trust the curve as much as the readings. Our guide to cents covers how large these differences actually are in musical terms. For nearby instruments with more to adjust, the tin whistle tuner and the recorder tuner both cover the same warm-instrument and breath-pressure effects with a joint you can actually move.
Frequently asked questions
How do you tune an ocarina?
You do not — the maker did it when the clay was still workable, and once it was fired the pitches were fixed. There is no slide, no joint, no reed and no peg. Everything you can change about an ocarina’s pitch is breath: how hard you blow, which moves every note, and how consistently you apply it across the range. That makes a tuner unusually useful here for a purpose it does not usually serve — not to correct the instrument, but to find out whether the instrument or the player is responsible for a note being off.
What is the breath curve?
The relationship between how hard you blow and which note you are playing. On an ocarina, low notes need very little air and each higher note needs progressively more — so playing in tune across the range means continuously increasing pressure as you ascend and easing it as you descend. That rising curve is not a flaw, it is how a vessel flute works, and it is the main technique to learn. It is also the diagnostic: a well-made ocarina has a smooth, predictable curve, and a badly tuned one does not.
How do I tell whether my ocarina is badly tuned or I am playing it badly?
Measure the breath curve. Play up the scale slowly with a tuner running, blowing just hard enough for each note to speak cleanly, and note what the pitch does. On a good instrument you will find that each note needs a little more air than the last and that each sits close to correct at its own natural pressure. Two findings point at the instrument rather than at you: notes that are sharp even at the minimum pressure that will sound them, and a range where the required pressure does not increase at all. Both mean the tuning was set badly before firing.
Why do my high notes squeak or go sharp?
Usually too much air, and occasionally an instrument that cannot do better. The top of an ocarina’s range needs the most pressure of anything you play, and it sits close to the point where the note stops speaking properly and breaks up — so the margin between “clean” and “squeaking” is narrow up there. Try backing the pressure off until the note is just barely speaking and see where the pitch lands. If it centres, it was your air. If it is still sharp at the least air that will sound it, the instrument is sharp in that register.
What note should an alto C ocarina play with all holes covered?
C — that is what the name describes. A 12-hole alto C ocarina covers a range of about an octave and a fifth, and with every hole closed it sounds its lowest note, C. If yours reads something else entirely, check the display’s octave digit before concluding anything, since ocarinas come in soprano, alto and bass sizes that play the same written notes in different octaves. If it reads a note that is not C at all, either you have a different key of ocarina, or a hole is not fully sealed by your fingers.
