Haynes Amadeus AF670-C Alto Flute Overview
The Haynes Amadeus AF670C is a performance-level G alto flute that combines a silver-plated body and mechanism with a solid silver curved headjoint. The curved configuration makes the instrument particularly relevant to flutists seeking the lower register and broader tonal palette of the alto flute with a more compact playing position.

Common Questions About the Haynes Amadeus AF670-C
What distinguishes the AF670-C from the standard AF670 configuration?
The C designation identifies the curved-headjoint configuration. This instrument pairs that curved design with a solid silver Haynes Classic headjoint and a silver-plated body and mechanism.
Why might a player choose a curved alto flute headjoint?
A curved headjoint places the embouchure hole closer to the player, reducing the reach required to support and operate the alto flute. Many players prefer this arrangement for seated playing, doubling, and extended rehearsals.
Where does an alto flute fit musically?
The alto flute extends the flute family's color into a lower register and is used in flute choirs, chamber ensembles, contemporary orchestral writing, theater, and studio work.
