What problems should be paid attention to when learning piano and accordion? Which one will have more room for development in the future?

I have been studying piano for many years, and I have been sparring with others in my spare time, so I have met many people of different degrees. I think the reason why many people can't practice their left hand well is that they don't know how to slow down, especially the granularity of touching keys is very poor. I suggest you practice Hanon first, practice with metronome, and be patient. Piano needs great ambition and endurance, but it doesn't need too many times. You must feel the feeling of touching the keys. I can't describe it well, but you can feel the power concentrated on your fingertips. When you go down with this finger, the other fingers will be shocked. This is the foundation. In addition, your fingertips must be arranged, because your level is not particularly deep, so the hand shape of your left hand is also very important for beginners, but don't ignore your right hand, because in fact, the colorful part of your right hand in big music requires speed.

The above is a little advice for you during your internship, and the following are recommended shops for you:

First, Hanon.

It's best to practice the whole book, but don't be too demanding. Practice the strength of your hands and fingertips.

Second, the scale.

Practicing scales not only practices knowledge of music theory, but also exercises fingers, especially when you find the law of ascending and descending, you will find that it is actually very simple. You can continue to practice harmony minor and melody minor, then the strength of chords is also the key, and finally arpeggio. You can ask the precautions for practicing these carefully. Finally, I think you can exercise yourself according to the standard of grading, write down the key signature on the note yourself and draw lots, just stick to it. PS: chromatic scales can also be practiced.

There should be more room for piano development.
