愛因斯坦演奏莫扎特小提琴奏鳴曲
先來說說愛因斯坦與小提琴的三個故事
上個世紀初,有一個猶太少年,他做夢都想成為像帕格尼尼那樣偉大的小提琴演奏家。他一有空就練琴,可是,就連他的父母都覺得這個可憐的孩子拉得實在太蹩腳了,完全沒有音樂天賦。…

今天我們了解一個小提琴的發音的物理性能,讓大家感覺到這些性能,從而能夠運用這些性能,這樣更有利於自覺形成對於一切違反這些性能的演奏動作本能的抵制。目的是提高發音的質量,增強音准。
1、音源:即弦。由於弦有張力,振則動,動則生波,這就是聲音的源泉。弦每秒震動440次,就是二弦的空弦音高,這是二弦的基本頻率,簡稱基頻;泛音的組合形成音色;弦的震幅大小產生不同的音量。這裡值得著重談一談的是音量大小取決於振幅大小的問題。演奏者要想奏出有力的音響,就要設法創造條件,加速運弓,多放重量,最終是使弦更充分地振動起來,擴大振幅從而擴大音量。但是,有些初學者誤認為用力「壓」緊弦會擴大音量,這是錯誤的方法,因為他違反了弦振動的物理特性。…
