Music is an art form and cultural activity whose medium is sound organized in time. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the color of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; there are solely instrumental pieces, solely vocal pieces (such as songs without instrumental accompaniment) and pieces that combine singing and instruments. The word derives from Greek μουσική (mousike; art of the Muses).[1]

The arapaima, pirarucu, or paiche are any large species of bonytongue in the genus Arapaima native to the Amazon and Essequibo basins of South America. Genus Arapaima is the type genus of the family Arapaimidae.[1][2] They are among the worlds largest freshwater fish, reaching as much as 3 m (9.8 ft).[1] They are an important food fish. They have declined in the native range due to overfishing and habitat loss[citation needed]. In contrast, arapaima have been introduced to several tropical regions outside the native range (within South America and elsewhere) where they are sometimes considered invasive species.[3] Its local name, pirarucu, derives from the indigenous words for pira meaning fish and urucum meaning red.Arapaima was traditionally regarded as a monotypic genus, but later several species were distinguished.[2][4][5] As a consequence of this taxonomic confusion, most earlier studies were done using the name A. gigas, but this species is only known from old museum specimens and the exact native range is unclear. The regularly seen and studied species is A. arapaima,[4][5][6] although a small number of A. leptosoma also have been recorded in the aquarium trade.[7] The remaining species are virtually unknown: A. agassizii from old detailed drawings (the type specimen itself was lost during World War II bombings) and A. mapae from the type specimen.[2][4][5] A. arapaima is relatively thickset compared to the remaining species.
