Practice Perfect
I’m writing about this because I’m terrible at it. Sometimes it’s really easy to get caught up in the flow a piece and just keep going every time it’s practiced. The reality is that if mistakes are practiced each time, mistakes will happen in performance. The goal of practice time should be to play something perfect each and every time. If that means that something has to played slow or you have to use stop and go practicing, do it!
Above it all it’s about simplifying and breaking down. If you have an arpeggio passage with a rough chord change, don’t attempt to work on the chord change with the RH pattern. Just work the chord change first until it’s very secure, do the same with the right hand pattern, then put them together.
Practice perfectly, and make less mistakes in performance!
