Alto Flute

The alto flute is a lower and somewhat more unusual member of the flute family than the piccolo and standard C flute. Sounding a perfect fourth lower than the flute in C, the alto flute plays in the key of G. It has a sounding range from G below middle C to the G three octaves higher. Its sound differs from that of the C flute, despite its similar shape, due to the fundamental differences in size necessary to enable to lowest pitches to sound. The internal diameter (bore size) of the alto may be up to seven millimetres larger than that of the C flute, and is considerably longer, measuring approximately 880mm, compared to the 685mm of the C flute.
