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.
