I’ve found myself repetitively practicing the opening section to the piece i’m learning and not moving on to even the second page. Don’t get me wrong, the opening is now much better than it was but still isn’t at a point where I can play it perfect every time, hence why I continue to practice it. And i’m sure that since i’m still growing as a musician, my practice methods and habits may be the reason progressing feels slow. So I guess my question is when you’re learning something new, breaking it into sections, how good does a section have to be before practicing a different section? I feel odd playing something imperfectly and then moving on.

Is the initial intro to the first movement meant to be played strictly measured or more cadenza like? I am just beginning to look at this piece and wonder which spots require strict metronome practice. Thank you!
