Instructor's Notes
- Do Now
- Display the Do Now on the board
- Lesson
- Ask what phrases the students wrote down or remembered from the reading.
- Section: generally refers to several measures of music (often 2, 4, 8, or 16 measures) that sound like a single musical unit
- A-B-A Form: a song divided into three sections:
- Section A: measures 1-4.
- Section B: measures 5-7. Features contrasting sounds to Section A.
- Section A (repeated): measures 7-10.
- Ask students about returning the measure number. Go over the concept of passing around the measure number and make sure students understand how it would be helpful. (Since it allows you to change how long/short sections are without updating every function)
- Ask what phrases the students wrote down or remembered from the reading.
