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.^[1] The "bass flute in F" produced by Kotato & Fukushima is a contra-alto flute.
