Codex Arundel, folio 175r

Giant Trumpet

Leonardo faces a typical challenge for wind instruments with low tones: to produce bass sounds, these instruments reach great lengths, sometimes exceeding two meters.

Leonardo provides the instrument with a complex system of clefs that act as mechanical extensions of the fingers, allowing the musician to tap even the most distant holes.
It was not until the nineteenth century that the inventor and musician Theobald Boehm, developed modern mechanics for flute and clarinet, which are still used today for brass instruments such as the saxophone, with an idea not very different from the one Leonardo had.
