The lyrical themes found in bossa nova include women, love, longing, homesickness, nature. Bossa Nova was often apolitical. The musical lyrics of the late 1950s depicted the easy life of the middle to upper-class Brazilians, though the majority of the population was in the working class. In conjunction with political developments of the early 1960s (especially the 1964 military coup d'état), the popularity of bossa nova was eclipsed by Música popular brasileira, a musical genre that appeared around the mid-1960s, featuring lyrics that were more politically charged, referring explicitly to working class struggle.
