This arrangement provides opportunities for students at several levels. All students should be asked to pay close attention to the dynamics. The most important dynamic considerations come in measures 11-12 and 13-14. In this case the students will play the first segment quietly, and then in the following measures they will play a literal repetition at a louder level. Guitar 4 has one fretted note in measure 5. You should teach them how to play this by rote.
