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.

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.
