It is in the key of G, pitched a fifth above the concert flute and is a transposing instrument, sounding a fifth higher than the written note.

[1] The instrument is rare today, only occasionally found in flute choirs, some marching bands or private collections.

A limited number of manufacturers produce G treble flutes, including Myall-Allen and Flutemakers Guild.

The flutes have many of the same options as their larger C flute cousins, including sterling silver bodies, trill keys, and soldered keys.

It is very similar to a piccolo, and plays in the same range, although, because it is slightly larger, it has a different quality at the upper end of its register, and it has an extended lower register, as compared with the piccolo.
