học đàn piano là niềm vui

Piano is a musical instrument that is played with the fingers of the hand. The piano player is called a pianist. In the early days of creation, the sound of the piano was not as loud as the piano of the XX century, like the piano made by Bartolomeo Cristofori (1655 - 1731) made in 1720. The reason, the strain of the piano string was not as strong now.
