Ok, so far, so good, you managed your time and freed some time to practice, now the question is how much time you need daily practice?
I don’t want to talk like a school teacher, ” The more you practice, the more you learn.”
I agree with that, but sometimes it’s not possible, so I stick to 30 minutes to one hour per day. If you practice 30 minutes per day, I assure you to play that instrument like a pro after one or two years. Many people say that two years is too long. No, it’s not, assuming that you are investing in your life to learn a new skill. So the second parameter of how to practice music effectively is consistency.
