纯一度与纯八度的训练方法纯一度双音是指两个同音同时振动发声所形成的双音[谱例1]。纯一度双音的训练可从空弦开始训练,依次先在E A D依次训练。轻拉空弦E,然后在A弦一把位用4指轻拉E,再平和音高,直到二音完全一致产生和谐共振为止[谱例2]。
Pure and Pure Octave training methods Purely dual disco refers to the two-tone simultaneous vibrato sound formed by the two-tone [spectrum example 1]. Pure dual tone training can start training from empty strings, followed by the first in the E A D training in turn. Lightly pull the empty string E, and then use a 4-finger pull of E at the first place of the string A, then flatten the pitch until the two tones are exactly the same to produce a harmonic resonance [Example 2].
