BASS

in zoology, any of a large number of fishes, many of them valued for food or sport. The name bass covers a range of fishes, but most are placed in three families of the order Perciformes: Serranidae, including approximately 400 species of sea bass and grouper (qq.v.); Moronidae, sometimes considered a subfamily of the Serranidae and containing about 12 species, such as the striped and European basses; and Centrarchidae (sunfishes), including the black bass (q.v.), prized by fishermen. Many other fishes are also known as bass; among them are the channel bass, a drum (q.v.); the rock bass, a sunfish (q.v.); and the calico bass, a crappie (q.v.). in music, the lowest part in a multi-voiced musical texture. In polyphony of the sort that flourished during the Renaissance, the bass formed one of several relatively independent or contrapuntal melodies. During the figured-bass era (17th and early 18th centuries), the thorough bass, or basso continuo, furnished a base for accompaniments played with relative freedom, though bound by certain conventions as well as shorthand instructions inserted in figures above the bass. In the homophonic, basically chordal, musical styles of the later 18th and 19th centuries, the bass was of crucial structural significance as the lowest of parts and, thus, the foundation of harmony. In vocal music, the bass is the lowest male voice, with a typical range from the second E below middle C to F above; the basso profundo is low and rich, while the basso cantante (singing bass) is lighter and more lyric. Among instruments, the lowest-pitched member of a family is referred to as the bass, for example, the bass recorder or bass viol. The lowest-pitched member of the violin family is called a double bass (q.v.).
