I am 20 years old and have no piano foundation. Can I go to Yuyao Jiangnan Musical Instrument Store to learn piano lessons in summer vacation?
Of course you can learn. Who was born with a foundation? Since you are interested, you must learn.
Tuition depends on the teacher's level. High-level tuition is expensive, but you may be in a large class, usually about 20 an hour, which varies from place to place.
