The Periodic Table of Music History PowerPoint is a unit that I teach in about a week to a week and a half. I begin with the Music Elements: Melody, Harmony, Rhythm, Dynamics, Tone Color, Texture, Form, and Expression. You can download my Music Elements Note Sheet for free. I then have students listen to various listening examples from each time period to see how the Music Elements develop over the Musical Time Periods: Middle Ages, Renaissance, Baroque, Classical, Romantic, and 20th Century. The Presentation ends with a chart of all the data.
