Learn the first note first, then the next note. Don’t skip any notes. If you miss a note, go back to it and try it again. If you play the wrong note, go back and try again. Go as slow as you have to.
If we practiced like that all the time we’d make fast, consistent progress over the long term. It’s also the fastest way to completely learn something.
So why don’t we just do that? Do we forget? Is it less fun?
If you need a reminder, here it is. Learn the first note first.
