Piano terminology means staff, a musical symbol. It consists of five parallel horizontal lines. The distance between two lines is called interval, and the notes recorded on the lines and intervals indicate the sound level. If you need to remember higher or lower sounds than the five elements, you can add short horizontal lines above and below the five elements. Piano tuning is commonly known as tuning. Simply put, it is to tighten or loosen the strings to make them reach a certain pitch (international standard sound).

Piano maintenance:

First of all, the main sound of the piano is a wooden soundboard with nearly 230 strings and a cast iron frame connected to it. More than 220 strings are divided into several groups to form a string system: the average tension of each string is about 90 kg, and the total tension of the whole piano is about 20 tons. Because the strings, the iron frame and the soundboard are elastic, the strings become a comprehensive elastic body with great internal stress after being tightened.

Piano is sensitive to temperature. The suitable temperature is 20-25℃ and the relative humidity is about 40-70%. When the relative humidity is more than 75%, you can install a dehumidifier and a dehumidifier in the piano. Zhejiang, Fujian, Shenzhen, Zhuhai and other places are located in the subtropical maritime climate environment, so moisture-proof is an aspect that can not be ignored in piano maintenance.
