The most distinctive feature of all Azumi flutes is the Altus Z-Cut professional headjoint which responds quickly and easily and produces a full and rich tone in all three registers.
The Z-Cut head joint is handmade by Altus and is included on every Azumi flute. The attention to detail in the handmade process creates a more responsive and flexible tone. The head joint features a fairly rectangular-shaped embouchure hole which makes it responsive and clean with fantastic articulation. This head joint is open and free, singing easily in all registers. It is a head joint which begs to be played because it makes all those difficult things seem so much easier. Response from the low B to the high C; and even D, is immediate and flawless. The sound is open and full. The tone produced blends beautifully and is therefore very well suited for a band or orchestral setting. The response makes it a fantastic choice for jazz players as well, who sometimes have to jump from sax to flute and get the high C to pop as though it is easy.
