Common Questions About the Altus 1507SRB-CD-4
What is Britannia silver?
Britannia silver is a high-purity silver alloy containing 95.8 percent silver. In a flute headjoint, it is often selected by players seeking tonal depth, color, and a responsive but substantial feel.
How does the 1507SRB-CD-4 fit within the Altus range?
The 1507SRB-CD-4 belongs to Altus's handmade professional flute range. It is designed for serious ensemble, solo, conservatory, and professional work. Soldered tone holes with separately formed chimneys optimize resonance and timbre consistency.
What is the benefit of open-hole keys?
Open-hole keys support advanced finger technique and give experienced players additional options for pitch shading and contemporary effects. Five plugs are included for players who prefer a gradual transition to the open-hole configuration.
