1607 Handmade Series

Altus 1607 is another prominent breakthrough of our product design. Combining the most cutting-edge technology - Sintering and Seamed Tubing technology - with our introduction of Britannia Silver in flute making, 1607 has been a popular model among professional flutists.


A flute of sophistication and boundless possibilities. In addition to Britannia silver, 1607 adopts the seamed tubing and sinter method, allowing for an even arrangement of the silver molecule. Not only does it give the model a full tonal color which creates a vintage-like sound, but it also provides a stable and continuous vibration that enables the flutist to express lasting emotions.

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 seamed headjoint, body and footjoint, silver mechanism - soldered 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.

Seamed Tubing

Made from a flat piece of metal that is rolled, hand planished and then seamed, the Altus seamed tube is truly the only handmade flute tube available in modern production. Altus seamed tubes are slightly thinner and handmade in a choice of two types of silver – Britannia silver (1607) and Altus Silver (AL).

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.

Soldered Tone Holes

The tone hole chimneys are formed separately and then soldered to the flute joint. This process allows for a consistent wall thickness around the holes and thus enables an even better resonance and timbre.
