Rock is a genre of music. Unlike other genres of music (e.g., classical, jazz, etc), there does not seem to be unique music theoretic features shared by rock songs (e.g., specific musical forms, harmonic language, etc). Rock songs have a typical instrumentation of electric guitar, electric bass, drumset, and oftentimes keyboard.
Unfortunately I did not take more structured notes from the rock history class I took. There are some notes scattered around daily notes if you refer to my class notes' backlink section.
你听那“摇滚乐”和“语录歌”都唱的什么?没有什么不同,你要忽略那些歌词直接去听春天的骚动,听它的不可压抑,不可一世,听它的雄心勃勃但还盲目。你看那摇滚歌手和语录歌群,同样的声嘶力竭,什么意思?春光迷乱!春光迷乱但绝不是胡闹,别用鄙薄的目光和嘴角把春天一笔勾销。想想亚当和夏娃走出伊甸园时的惊讶与好奇吧。想想那条魔魔道道的蛇,它的谗言,它的诱惑,在这繁华人世的应验吧。想想春风若非强劲,夏天的暴雨可怎样来临?想想最初的生命之火若非猛烈,如何能走过未来秋风萧瑟的旷野(譬如一头极地的熊,或一匹荒原的狼)?
因而想想吧,灵魂一到人间便被囚入有限的躯体,那灵魂原本就是多少梦想的埋藏,那躯体原本就是多少欲望的储备!因而年轻的歌手没日没夜地叫喊,求救般地呼号。灵魂尚在幼年,而春天,生命力已如洪水般暴涨;那是幼小的灵魂被强大的躯体所胁迫的时节,是简陋的灵魂被豪华的躯体所蒙蔽的时节,是喑哑的灵魂被喧腾的躯体所埋没的时节。万物生长,到处都是一样,大地披上了盛装。一度枯寂的时空,突然间被赋予了一股巨大的能量,灵魂被压抑得喘不过气来,欲望被刺激得不能安宁。我猜那震耳欲聋的摇滚并不是要你听,而是要你看。灵魂的谛听牵系得深远那要等到秋天,年轻的歌手目不暇接。现在是要你看,看这美丽的有形多么辉煌,看这无形的本能多么不可阻挡,看这天赋的才华是如何表达这一派灿烂春光。年轻的歌手把自己涂抹得标新立异,把自己照耀得光怪陆离,他是在说:看呀—我!我?可我是谁?
