Forgot to say the head teacher at the preschool he attends plays guitar everyday while they sing AND they have songs throughout the day for reminders of what they are to do, are doing, etc., plus they play beautiful instrumental music when they have rest time. I know his teachers value the way the music focusses and directs the children, while making it fun. Morgan often comes home and will sing one of the rhyming directive songs he's learned in school.
