It proves effective fruit, only a kind of possible method, is exactly train hard, but finally can only also accomplish quickly to play rather than scrape and play.Example
Such as, Yao Shanghang plays the chromatic scale glide in a simplest c major octave area, it is necessary to by it is white-black-white-black-and-white-white-
Black-White-Black-White-is black-and-white-white key sequence key, any two neighboring key is all half sound relationship, and since white-black key is one high and one low,
It can not scrape and play on keyboard anyway.Current method can only go out like flying refer to fastly in height by train hard
It is played as making to like a dragonfly skimming the surface of the water in keyboard, even being also difficult to reach in terms of the level of professional concert performer, speed and uniformity, fluency
To ideal state, such as the chromatic scale of big minor third is played, and is played by singlehanded two fingers there are speed and the uniformity upper limit, double
Hand bullet is also to have dynamics and speed limit；It is all extremely difficult for many professional piano performers.
Should not excessively resting on for the purpose of performance is shown off in artistic skills, ultimate purpose should be show works thought and
Emotion.Current all keyboard instruments are all this chequered with black and white, by high and low traditional designs, although being not really defect,
Hei Gaobai low design always exists flaw, is exactly the fluency performance for seriously hampering chromatic scale glide, considerably increases nothing
It is paid by the training of amateurish or professional performance personnel.Strictly, this is the place of current keyboard instrument blemish in an otherwise perfect thing, should be had
