<P> Other types of music--including, but not limited to, jazz, blues, soul, and country--are often performed in bars, nightclubs, and theatres, where the audience may be able to drink, dance, and express themselves by cheering . Until the later 20th century, the division between "high" and "low" musical forms was widely accepted as a valid distinction that separated out better quality, more advanced "art music" from the popular styles of music heard in bars and dance halls . </P> <P> However, in the 1980s and 1990s, musicologists studying this perceived divide between "high" and "low" musical genres argued that this distinction is not based on the musical value or quality of the different types of music . Rather, they argued that this distinction was based largely on the socioeconomics standing or social class of the performers or audience of the different types of music . For example, whereas the audience for Classical symphony concerts typically have above - average incomes, the audience for a rap concert in an inner - city area may have below - average incomes . Even though the performers, audience, or venue where non - "art" music is performed may have a lower socioeconomic status, the music that is performed, such as blues, rap, punk, funk, or ska may be very complex and sophisticated . </P> <P> When composers introduce styles of music that break with convention, there can be a strong resistance from academic music experts and popular culture . Late - period Beethoven string quartets, Stravinsky ballet scores, serialism, bebop - era jazz, hip hop, punk rock, and electronica have all been considered non-music by some critics when they were first introduced . Such themes are examined in the sociology of music . The sociological study of music, sometimes called sociomusicology, is often pursued in departments of sociology, media studies, or music, and is closely related to the field of ethnomusicology . </P> <P> Women have played a major role in music throughout history, as composers, songwriters, instrumental performers, singers, conductors, music scholars, music educators, music critics / music journalists and other musical professions . As well, it describes music movements, events and genres related to women, women's issues and feminism . In the 2010s, while women comprise a significant proportion of popular music and classical music singers, and a significant proportion of songwriters (many of them being singer - songwriters), there are few women record producers, rock critics and rock instrumentalists . Although there have been a huge number of women composers in classical music, from the Medieval period to the present day, women composers are significantly underrepresented in the commonly performed classical music repertoire, music history textbooks and music encyclopedias; for example, in the Concise Oxford History of Music, Clara Schumann is one of the only female composers who is mentioned . </P>
