“Short cuts make long delays.”
In the practice room, you will save an awful lot of time by practicing something slowly and correctly the first time. Whenever we learn a passage with a wrong note or wrong rhythm, it takes a lot longer to unlearn the mistake than it ever would have taken to learn it right in the first place.
The ability to have the in the moment intelligence to know that practicing something slowly and correctly is always the correct path rather than seeking instant gratification is what separates great practicers from everyone else.
Short cuts never pay off in the practice room.
