1307 Handmade Series

As the first flute manufacturer to introduce .958 Silver into the production, Altus led the way in the constant pursuit for beautiful Louis Lot flute sound and quality flute-making. The Altus 1307 incorporates the .958 Silver and the modern seamless tubing technology, resulting in the creating of 1307.


Altus 1307 adopts Britannia silver and brings about pure ringing sound with tenderness. Just as 958 silver serves as the stepping stone for Altus towards reviving the Louis Lot flute, this model can certainly assist you along the musical pursuit.

Altus Scale

An instrument’s scale is determined by the size and placement of each of the tone holes and their relationship to each other. This crucial design aspect allows flutists to play with accurate intonation and effortless tone.

Altus flute maker Shuichi Tanaka and renowned British flutist William Bennett shared an admiration for Albert Cooper’s vision of updating and modernizing the traditional flute scale. Mr. Tanaka created the Altus Scale in cooperation with Mr. Bennett with vast performance experience and quest for precise intonation.

The collaboration of Tanaka and Bennett set a new standard for flute design. The Altus Scale was carefully designed to provide effortless intonation, impeccably tuned harmonics, and exceptionally balanced registers. This monumental achievement is one of the hallmarks of the great Altus flute making tradition.

Material Composition

Sterling silver lip-plate and riser, Britannia silver headjoint, body and footjoint, silver mechanism - drawn tone holes


A traditionally created silver alloy composed of 95.8% silver, also dubbed the Britannia Silver for its historic existence in British coinage. Mr. Tanaka first created Altus flutes with this alloy for a Renaissance of 19th century flute sound. This alloy has an increased density and is considerably softer than Sterling Silver. This allows the instruments to make darker and richer tonal color without the use of greater wall thickness.

Reliable Key Pipes

Altus Handmade Series feature Pristine Silver with powder metallurgy, a process where powdered silver metal is compacted at high pressure to fuse particles together directly into a rigid tube, to strengthen our key pipe structure and increase playability and sustainability.
