But rhythm and timing and note relativity are ridiculously hard to get right (especially for beginners). This is a great exercise for one of the more challenging parts of playing music well. Plus, the audience is much more likely to notice a mistake if the rhythm is wrong than they are to notice a note is wrong. If you can get the rhythm right you can play through your other mistakes and still have a reasonable presentation.
