"Practice makes perfect" is a phrase I can guarantee you've heard before. You may have also heard "practice makes permanent"... Either way, there's truth to the statement. The way we practice is important! If we skip over missed notes and never correct them, we will never hit the correct notes when we are performing. If we don't sing the correct lyrics when we are practicing, we will likely not sing the right words when we perform. It's during our practice that we should take time to get it right.
