The alto flute is a type of Western concert flute, a musical instrument in the woodwind family. It is the next extension downward of the C flute after the flûte d'amour. It is characterized by its distinct, mellow tone in the lower portion of its range. It is a transposing instrument in G and, like the piccolo and bass flute, uses the same fingerings as the C flute. The tube of the alto flute is considerably thicker and longer than a C flute and requires more breath from the player. This gives it a greater dynamic presence in the bottom octave and a half of its range.
