About the bass flute

The bass flute is a member of the flute family pitched one octave below the concert flute. The tubing length is twice as long at 146 cm (57 in), which requires a J-shaped head joint to bring the embouchure hole within reach of the player. Despite its name, its lowest note of C3 or B2 places its lowest octave only in the tenor range. Its soft dynamic range means in large ensembles it is easily obscured unless amplified or lightly scored; however its unique timbre in the low register can be very effective, especially in solo works, small ensembles, and flute choirs.

The "bass flute in F" produced by Kotato & Fukushima is a contra-alto flute.
