Common Questions About the William S. Haynes Amadeus AF670-C

What is the benefit of having a curved headjoint?

A curved headjoint reduces the distance between the player's mouth and hands, allowing the arms to remain closer to the body. This makes the instrument more accessible to players with shorter arms or smaller hands. It also reduces stress on the shoulders, arms, wrists, and neck, particularly during extended performances.

How does the AF670 differ from the Amadeus AF570?

The principal construction difference is the headjoint. The AF670-C uses a solid-silver curved headjoint, while the AF570-C uses a silver-plated curved headjoint with a solid-silver riser.

Where is an alto flute commonly used?

Alto flute is widely used in flute choirs, contemporary chamber music, film and studio work, orchestral doubling, and repertoire requiring a lower and more rounded flute color.
