Piano three-degree and six-degree precise tuning method

Abstract

The invention relates to a piano three-degree and six-degree precise tuning method which has nine operation steps for three and six degree tuning. The test conditions of the piano three-degree and six-degree precise tuning method are more and can be selected for use by different levels of tune technicians. The piano three-degree and six-degree precise tuning method can freely adjust three and six degree bit frequency speed of the same-rooted tone, avoids hearing difficulties with more than seven beats because more intervals can be adjusted to be below seven beats for perception, and consequently can be grasped by most tune technicians. Because multiple test methods are convenient and accurate and have small raw tune error accumulation, the piano three-degree and six-degree precise tuning method brings intonation guarantee for performance of concerts, two pianos or multiple pianos.

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] 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, this has also seriously affected the popularization...
