This is not absolute, only relative, but it is difficult to get started with violin and simple to get started with piano. In fact, the absolute difficulty of piano will only appear later, but many people can't play it at all. It's really not difficult to play the keys properly and have a good voice in piano performance, but it's very difficult to play the voice fully, with strength and aesthetic feeling as high as that of emotional contagion.

Violin: It is a stringed instrument. There are always four strings. The friction between the strings and the bow produces vibration, and then the vibration is transmitted to the back plate through the sound column in the * * * sound box, and the * * * vibration generated by these components gives out a harmonious and bright piano sound.

The piano body (* * * sound box) is about 35.5 cm long and consists of a curved panel, a back panel and side panels. Panels are usually made of soft spruce; The back plate and side plate are made of maple and peach, which are hard. The head and neck of the piano are all maple, and the fingerboard is ebony.

Piano: Italian: piano, a keyboard instrument in western classical music, has the reputation of "the king of musical instruments". It consists of 88 keys (52 white keys and 36 black keys) and a metal chord board. Italian Bartolomeo Christofi (1655- 173 1) invented the piano in 1709.
