各位老大我的问题不是叫你们翻译啊！而是叫你们回答啊！

It has been thought and said that Africans are born with musical talent.Because music is so important in the lives of many Africans and because so much music is performed in Africa,we are inclined to think that Africans are musicians.The impression is strengthened when we look at ourselves and find that we have become largely a society of musical spectators (旁观).Music is important to us,but most of us can be considered consumers rather than producers of music.We have records,television,concerts,and radio to fulfill many of our musical needs.In most situations where music is performed in our culture it is not difficult to distinguish the audience from the performers,but such is often not the case in Africa.Alban Ayipaga,a Kasena semiprofessional musician from northern Ghana,says that when his flute (长笛) and drum ensemble (歌舞团) is performing.“Anybody can take part”.This is true,but Kasena musicians recognize that not all people are equally capable of taking part in the music.Some can sing along with the drummers,but relatively few can drum and even fewer can play the flute along with the ensemble.It is fairly common in Africa for there to be an ensemble of expert musicians surrounded by others who join in by clapping,singing,or somehow adding to the totality of musical sound.Performances often take place in an open area (that is,not on a stage) and so the lines between the performing nucleus and the additional performers,active spectators,and passive spectators may be difficult to draw from our point of view.
