I
In zoology, any of numerous fish species, many valued for food or sport.
Most are placed in three families (all in the order Perciformes): 400 species of sea bass and grouper ; the family Moronidae, which contains about 12 species, including striped and European basses; and black and largemouth basses, prized by fishermen. Many other species are also known as bass, including the channel bass (a drum ) and the calico bass (a crappie ).
II
Lowest musical voice or register.
In vocal music, its range is approximately from the second E below middle C to middle C itself. A basso profundo emphasizes a lower register, a basso cantante a somewhat higher one. Outside of Russia, the solo bass voice has generally been relegated to certain standard operatic character roles. The lowest-pitched member of most instrumental families is usually called the bass (bass clarinet, double bass , etc.). In Western tonal music, the bass part is usually second in importance only to the melody, being the chief determiner of harmonic movement, a tendency that became particularly notable after the appearance of the basso continuo с 1600.
