12-Hole Alto C Ocarina Finger Chart Sub-Holes Included

An ocarina is a Helmholtz resonator: pitch depends on the total open-hole area, not which holes are open — which is why cross-fingerings work and why charts differ slightly between makers. On the common 12-hole Alto C, natural notes follow a clear opening sequence through the right hand, left hand, and two thumb holes. The two small sub-holes extend the bottom of the instrument's range and must be sealed as carefully as the larger holes.

The 12-hole layout: eight finger holes, two thumb holes underneath, two subholes. Dashed = underside.

The lowest notes can sound weak or breathy until both sub-holes seal cleanly and the breath pressure settles. Upper accidentals vary most between instruments: this table uses one common cross-fingering, while some makers specify a different closed hole. If your tuner and the chart supplied with your instrument disagree with this page, use your instrument’s chart.

This page is intentionally limited to the common 12-hole Alto C system. The same rows drive the fingering renderer used in Soloist Ocarina lessons and play-alongs, so the reference and the course cannot silently describe different hole patterns.

Questions

Why doesn't this chart match the one that came with my ocarina?

Because an ocarina's pitch comes from total open area, makers can tune the same note with different hole combinations — accidental fingerings especially vary. The natural-note sequence is shared by the common 12-hole Alto C system; for sharps and flats, your instrument's own chart wins if the two disagree.

What are subholes and how do I actually play them?

They're two small holes drilled beside main finger holes, covered by sliding the fingertip forward so one pad seals both at once. You only close them for the lowest three notes: slide onto the B-subhole for B4, add the A-subhole for A4 — everywhere else, leave them open and forget them.
