Due to the length of the instrument, the lowest tone, F, requires a key. On modern instruments, keys may also be provided for low F♯, G, and G♯, and sometimes for C and C♯ as well.
In the early 17th century, Michael Praetorius used the diminutive term "basset" (small bass) to describe this size of recorder as the lowest member of the "four-foot" consort, in which the instruments sound an octave higher than the corresponding human voices. Praetorius calls the next-lower instrument (bottom note B♭2) a "bass", and the instrument an octave lower than the basset (with bottom note F2) a Großbaß, or "large bass".[1][2]
The bass is usually the lowest instrument of the recorder consort, but it may be used as an alto in "eight-foot" register in the so-called "great consort" or grand jeux, in which case two larger sizes of bass recorder take the lower parts and a tenor may be used as an optional descant.[3]
Composer Ludwig Göransson employed a bass recorder for the opening melody of the TV series The Mandalorian. The melody features prominently throughout the series. [4]
