How the contra-alto flute makes its sound
In the Hornbostel–Sachs system, which classifies instruments by how they produce sound, the contra-alto flute belongs to the flutes (edge-blown): an air jet is split on a sharp edge, setting the air column vibrating – flutes, recorders, whistles and panpipes.
More broadly it is one of the aerophones (wind instruments), where sound comes from vibrating air.
Its timbre – the colour that lets you tell it apart from other instruments playing the same note – comes from the mix of overtones its body and resonator emphasise.
From Wikipedia
The contra-alto flute is a large member of the flute family, pitched between the bass and the contrabass. It is a transposing instrument either in G (a perfect fourth below the bass and one octave below the alto) or in F (a perfect fifth below the bass and a major ninth below the alto). The instrument's body is held vertically with an adjustable floor peg similar to that of the bass clarinet. The instrument maker Eva Kingma calls her contra-alto flute a "contr'alto flute in G", while Kotato & Fukushima call their instrument a "bass flute in F". Kotato & Fukushima's instrument sells for US$17,500.
