Answer to Question 1ANSWER: Answers will vary.
Communities carry the cultural traditions and norms, social processes and activities, and ideas of performance that enable musical performances and make sense of them.
Communities need not consist of people living in geographical proximity; they may include people who live far from one another but who gather on particular occasions or are linked via media such as the Internet.
Musical communities may be largely participatory, in which case most if not all people perform music in groups; or they may be largely accustomed to identifying themselves as performers or audience.
Communities carry the memory of music from the past and construct histories of music that inform the present and help shape the futures of music.
Answer to Question 2ANSWER: Answers will vary.
The four categories of ideas about music are: music and the belief system, aesthetics of music, contexts of music, and history of music.
Music-cultures do not necessarily present a united front in their ideas about music.
Certain types of musicsuch as jazz, rock, rap--met opposition from some when introduced. This opposition may be based on aesthetics (the music was thought to be awful by those who opposed it) and context (opposition to the lifestyle of the musicians).
