萨克斯超高音域的演奏(超吹)是对萨克斯正常演奏音域的扩展,是萨克斯的高级演奏技巧;之所以称为高级技巧,是因为对超高音域的演奏要建立在对正常音域熟练掌握的基础上的。
对超高音域的唯一衡量标准必须是它的音乐价值,而绝不能将其当作一种花招和噱头使用。如果开发出来的音有美妙的音色、良好的音准、精确的控制,那么它给演奏者带来的是恩惠的裨益;反之只能是无音乐的尖叫,甚至对演奏者的演奏方法有影响。
尝试超高音演奏的人只应限于具备良好口型和有准确音高辨别感觉的高级萨克斯演奏者,第二个条件尤其重要,因为在该音域里发音必须在它们发出音响之前就要感觉到它的音高;这一音域的指法位置仅仅是根据所要产生的音的声学可能性设定的,因而它决不起什么保险作用;实际的音高是通过唇和气息的控制而达到的,所以在掌握良好的口型和气息之前,过早的在超高音域上努力,不仅会阻碍学习的进步,实际上还会损害脆弱的神经系统和嘴唇的肌肉,以致于造成永久性伤害。
由于超高音域是建立在普通音域上的,因而需要在熟练控制基音后再进入较高层次的泛音的练习。首先应当从事加强对泛音系列适应性的初步练习,在一个指法不变的基础上,象铜管一样去尝试向上做泛音时口型和气息的变化,并试图按泛音列去控制;通过反复的练习,你会找到并确定诸如气息支撑、口型压力、和喉的姿势的正确混合比例(注意:口型的压力不能和咬压混为一谈),在具备了基本的控制能力之后,就可以参照良好的超高音域的指法表去练习,最后把它做为音阶练习的延续,直至可以运用到乐曲之中。
另外乐器本身特别是笛头、哨片的性能对超高音域的影响也是非常大的,建议在练习前最好拥有一只性能较好的笛头和乐器,这将会让你尽快成为一个萨克斯演奏高手!
不知道你用的是高音萨克斯还是中音萨克斯,先发一张中音的吧。
练习超吹,脑子里必需要有音高、音准概念,因为除了配套的超吹指法以外,嘴型的控制,音准的把握也是必不可少的。其次就是嘴巴的控制,理论来讲,音越高,嘴巴越紧,但是过紧,会导致风口憋死,下嘴唇咬破等情况,所以说,嘴巴的松紧不是关键,关键是发音的点,或者是含笛头多少的这个点。练习的时候就会发现,吹奏出超高音,嘴巴往往是一个放松的状态!
练习超吹时,时间也不易过长,音越高,时间越长,人的大脑对高音音准的判断也就越模糊。而且长时间练习,也会刺激耳膜。
把中音,和次中音的指法分开了。因为管子不同,泛音列的指法就会不一样。同一指法,中音也许吹的出来,次中音也许就吹不出来了。发现一个规律,如果同一指法都能吹奏出来的时候,次中音的音高比中音的音高要低一个小二度。也就是低半音。
