Bosanova
Bosanova, bossa nova (port. bossa nova) is a genre of Brazilian popular music that is a synthesis of local folklore and jazz: it combines the rhythm of Brazilian urban samba and the harmony of American jazz (i.e., a type of extended chromatic tonality). The rhythm of bossa nova does not manifest itself in the melody (usually simple, consisting of ostinato and/or sequenced short motifs), but in the accompaniment. A specific accompaniment was developed in the 1950s by Brazilian pop guitarist, singer and songwriter João Gilberto. Its essence is syncopated rhythm formulas, usually covering two bars (4/4 size).
