As long as you practice piano music frequently and practice your finger strength more, you can cross more.

Piano (Italian: pianoforte) is a keyboard instrument in western classical music, and 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 soundboard. Italian BartolomeoChristofori (1655-1731) invented the piano in 179. The piano has a range from A2(27.5Hz) to C5(4186Hz), which covers almost all the musical tones in the music system. It is the instrument with the widest range except the organ. Piano is widely used in solo, ensemble and accompaniment performances.
