Piano Thirds and Sixths Accurate Tuning

Abstract

The invention relates to a method for precise tuning of piano thirds and sixths, the operation steps of which are altogether nine steps for tuning the thirds and sixths. This method consists of many test conditions, which can be selected by tuners at different levels. This method can freely adjust the beat frequency speed of the same root note at three or six degrees. The auditory difficulties with a frequency of more than seven beats can be mastered by most tuning lawyers. Due to the convenience and accuracy of multiple testing methods and the small accumulation of rhythm errors, it brings pitch accuracy to concerts, performances of two pianos or multiple pianos. protection.

Description

【Technical field】 [0001] The invention relates to a piano tuning method, in particular to a piano third and sixth accurate tuning method capable of expanding the inspection range of 33 to 44 keys. 【Background technique】 [0002] TD stands for Thirty-Six Tuning. [0003] Over the years, there have been roughly two types of piano tuning laws in the world: "four-fifth degree tuning law" and "three-sixth degree tuning law". The four-fifth degree test is accurate, so tuners often use the three-degree, six-degree and four-fifth degree tests in combination when using the "four-fifth degree tuning method" or "three-six-degree tuning method". , the "four-five-degree tuning method" is easier to operate than the "three-six-degree tuning method", but the accuracy is not as good as the latter. In the field of 44-key testing, it is inevitable to listen to and distinguish the beat frequency of 7 to 10 beats, which is very difficult for tuning lawyers below the middle level. Rarely, th...

Problems solved by technology

[0004] In order to overcome the above-mentioned shortcoming of prior art, the present invention provides a kind of circle that can jump out of the check of 33 keys to 44 keys, expands the check of 33 keys to 44 keys Scope, adding untuned into the inspection step, solved the second and third steps of inspection that have not been solved by other tuning methods (the second and third steps of the three-six-degree tuning are the key steps), Better avoid the accumulation of errors, and easy to master the precise tuning of the third and sixth degrees of the piano
