Tom Zé, Casa das Caldeiras

Tom Zé (Portuguese pronunciation: [ˈtõ ˈzɛ]; born Antônio José Santana Martins, 11 October 1936 in Irará, Bahia, Brazil) is a songwriter, multi-instrumentalist, and composer who was influential in the Tropicália movement of 1960s Brazil. After the peak of the Tropicália period, Zé went into relative obscurity: it was only in the 1990s, when the musician and label head David Byrne discovered an album recorded by Zé many years earlier, that he returned to performing and releasing new material.

Music is an art form whose medium is sound and silence. Its common elements are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics, and the sonic qualities of timbre and texture. The word derives from Greek μουσική (mousike; "art of the Muses").

The creation, performance, significance, and even the definition of music vary according to culture and social context. Music ranges from strictly organized compositions (and their recreation in performance), through improvisational music to aleatoric forms. Music can be divided into genres and subgenres, although the dividing lines and relationships between music genres are often subtle, sometimes open to individual interpretation, and occasionally controversial. Within "the arts", music may be classified as a performing art, a fine art, and auditory art. There is also a strong connection between music and mathematics.
