I teach Music in Term 2 each year. Each unit of work I do starts off very similar for the whole school, as it's been a year since we last learnt Music. I like to engage the students with an interactive Boomwhackers lesson, followed by a Percussion instrument lesson, Keyboard lesson and then move into the unit of work. The students love it and it's a great way to revisit past concepts and allow them to express themselves with musical instruments.
In Stage 2 and 3 I alternate on a 2 year cycle, two units of work. One unit is called, "Just Play: Exploring the Keyboard, Drums and Ukulele". In this unit after learning the basics of the 3 instruments, the students choose one and are to use that instrument to learn and play a song of their choice.
The other is called, "Just Play: Creating a Composition". Students again learn the basics of some instruments and then work in groups to create a small composition, using a variety of instruments. Both units involve students learning to play different instruments and working in groups to create music.
