The contrabass flute is one of the rarer members of the flute family. Typically seen in flute ensembles, it is sometimes also used in solo and chamber music situations. Its range is similar to the regular concert flute, except it is pitched two octaves lower. (...) Many contrabass flutes in C are also equipped with a low B (in the same manner as many modern standard-sized flutes are). (Wikipedia, 28.01.2026)
