听民歌

  ①听过民歌。

  ②陕北信天游、陇东花儿、江南田歌、闽北山歌。

  ③从小听的闽北山歌,曲调很简单,旋律似乎只有一句。这一句翻来覆去地唱,翻来覆去地唱。只在每句的结尾略加不同的装饰音,以与下一句相区别。那时,常有一个老翁,走在弯弯的崎岖长路上,他一边赶着牛,一边豁开嗓子扯出一首首山歌。没有应和,没有对答。老人的嗓子孤独、苍老、悲凉。有时他根本发不出音。老人走在牛群的背后,唱得再也唱不下去了,就沉默。老人是终日与牛群为伴的牛倌。那时,我听不懂老人唱的山歌,因为隔得太远,老人又豁了牙,吐字不清。但我至今闭上眼睛,还能清晰地浮现出一条长路上的一群牛,一个老翁,一首首拖音很长的山歌。

  ④后来参加山场劳动,穿蓑衣、挂柴刀、扛长锄去山上,开始近距离地听到男女对唱的山歌。男的女的两拨人,往往分得很开,往往是隔着一条山冈,这边望得见那边的人,那边望得见这边的人。第一个音是这样发出的,有人觉得要唱了,就停下手中的活儿,把箬帽往脑后掀了掀,吸一口气,然后扬脖仰头。“哎——”,这个哎字由低往高,高到一定音阶。然后平滑着延伸,“哎——”,然后波动,上挑,收尾。接下的句子是“妹呀……”什么什么的。这是典型的中青年唱的山歌,底气十足、穿透力强,同时也是粗野的、质朴的。山中的人并不指望什么爱情,但是他们唱的却是纯粹的爱歌。如果认真地听他们彼此间的对唱,还真的唱得情深意长。与老人们的山歌相比,年轻人的山歌欢快、短促,更加明快也充满向往。年轻人是对着异性唱,老人则是对着大山和天空唱。

  ⑤时间继续往后推移,就听到了乐清的著名山歌《对鸟》。《对鸟》的旋律要比闽北山歌复杂、华丽得多,而且歌词也来得更加富有情趣和圆熟。与闽北相比,乐清的山没有那里的深,没有那里的高,也没有那里的大,但人也因此而复杂了许多,山歌也因此而华丽了些,想来并非没有道理。

  ⑥如今听民歌,是听磁带上、音响中的民歌,流畅,华彩,大白菜上扎红绸,早已没有了那种质朴。从歌星那猩红的嘴唇间和花花绿绿的MTV中唱出,“民歌”已不再是民歌了。
