Just as novice musicians must spend many hours practicing basic skills like playing scales or mastering difficult passages--and frequently do so in the presence of their teacher, receiving immediate and individualized feedback--so must our students spend many hours practicing the basic intellectual skills of our discipline.

You will be doing your students a much greater service by reducing the amount of material that you are covering and actually ensuring that students are learning it, rather than making sure that you are ticking off everyone checkpoint in your ideal syllabus. Learning comes from practice, and you have to help and teach your students to practice just as you help and team them the basic knowledge and skills of your discipline.
