Piano tuning is a professional skill, and only those who have certain musical literacy and professional training are qualified to become tuning lawyers. Piano tuning is very professional, unlike refrigerators and color TVs, you can know it at a glance until it is repaired. Unlike the piano, it is difficult for people without tuning training to make accurate judgments.

Ordinary piano practitioners can supervise tuning lawyers all the time. If it is a new piano, you can tell him to follow the standard sound. If you can obviously feel out of tune when playing before tuning, you must be accurate when playing after tuning.

After the melody of the piano is completely tuned, playing it again will give people a sense of beauty and sound very comfortable, which is a normal auditory reflection of the relationship between piano scales and purity.

Extended data:

If the pins and chords of the piano are rusted, someone will paint vaseline or oil on the pins and chords. If oil seeps into the holes of the pins, it will bring trouble to the piano tuning, and it can't be tuned carefully.

The oil stains on the strings stick to the sound head and hammer head of the damper, which will not only affect the color of the felt, but also deteriorate the sound control effect and timbre. The oil stain on the string will stick to the dust for a long time, which is unsightly, but its rust prevention ability is even worse.

If this happens. Rust spots on the chord shaft can be cleaned with a dry cloth dipped in a little gasoline and engine oil, and then the oil stain can be wiped off with a dry cloth. Slight rust spots on the strings can be adjusted with lead powder by alcohol and wiped with felt cloth until the rust disappears.

When playing, you should not slam the keys with your hands or pedal with your feet, so as not to cause mechanical damage to the strings and fracture of the pedal spring. Do not use sharp tools to describe the surfaces of keys and paint films.

Don't use too much force when opening and closing the piano cover. When opening and closing the piano cover, close the bookshelf first to avoid damaging the keys. After the piano is used, all the covers should be closed, and the piano box should be covered to prevent dust from invading.
