The bass flute is a member of the flute family. It is in the key of C, pitched one octave below the concert flute. Despite its name, its playing range makes it the tenor member of the flute family so it's really a Tenor Flute. Because of the length of its tube (approximately 146 cm (57 in) so twice the length of the Concert Flute), it is usually made with a J-shaped head joint, which brings the embouchure hole within reach of the player. 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.
