The difference between being in a good mood and being in a bad mood is as follows:
I am in a good mood: I tap my fingers on the black and white keys and dance on the keys like a lovely elf. The pop-up sound is like a spring, pouring down from your fingertips.
In a bad mood: fingers hit the keys and make a deep voice. The cat woke up from sleep and the sparrow flew away outside the window. I've been poaching upstairs, as if I'm going against the sky, preventing me from playing the piano.
Advantages of playing the piano:
Learning the piano can exercise the development of our left and right brains, because when playing the piano, we play with both hands, and the left and right hands have different voices and rhythms, which exercises the cooperation between our left and right brains. Learning piano can cultivate our sentiment, improve our artistic accomplishment and make the whole person exude a temperament and elegant image from the inside out.
After all, playing the piano is a skill and a hobby, which can kill leisure time and please yourself. You can also play for everyone at family gatherings or classmates' gatherings. If you like it very much, you can also consider becoming a professional performer, which is also very enjoyable.
