This is a four hole English pendant style ocarina.
It's tuned in G6 major.
The range is a full octave from G6 to G7.
A Fingering table is included in the images above.
A high resolution version is available here here
The highest notes are pretty loud.
The lowest are modest; blow in very gently for them!
Keep it dry and don't enclose it airtight
The White Strong & Flexible material works fine and is dyable too.
