How long does it take to play a song fluently? How long does it take to join the band?

I studied from scratch for three months, and I can play Beyond's songs fluently by 70%. Some simple pop songs can also be shot and played independently. Do more work. Climbing the grid for at least three hours every day is climbing the grid. Don't do some fancy skills, and practice them later. You must have solid basic skills. If you want to join the team, at least 300 songs can be successfully completed. Does not depend on the overall strength of the band.
