Flutes across the entire Azumi range incorporate the Altus scale — a modified Cooper scale designed by Altus flute maker Shuichi Tanaka and lauded British flutist William Bennett. The result is a flute with superior intonation and resonance, rewarding the player (and the listener) with enhanced sonic depth and color.
The Altus Z-Cut professional headjoint is touted by Azumi as their flutes’ most distinctive feature, responding quickly and easily and producing rich, full tones in all three registers. Furthermore, the Z-Cut boasts a fairly rectangular-shaped embouchure hole, which naturally gives it exceptional articulation and a clear, fast response.
