The cornetto is a musical instrument which combines a wooden body with finger holes (like the recorder) with the mouthpiece of a trumpet. It was, indeed, sometimes an alternate depiction of the trumpet, as in the emblazon of Trumpington in the Heralds Roll, c.1280 [ANA1 78]. The cornetto is curved in form, ranging from the default form in the first illustration, to the so-called “bass cornetto” or “Serpent” in the second illustration.
The Society has the cornetto following the default orientation for other woodwinds: with the mouthpiece to chief. For related charges, see horn.
The Master of the King’s Musick of Atenveldt bears: Per pale azure and argent, in canton a sun in his splendour Or, in sinister a bass cornetto sable.
