Piano Fun, A Trigonometry Activity

Using their trigonometry skills, students are going to determine how often any one key, or note, is played on a standard 88 key piano (keyboard). Your students will first need to find the common ratio between all the keys (the 52 white keys and the 36 black keys). Then, they will narrow down further by using the common ratio that was found to determine the use of higher or lower frequencies. The final step will be to create a sin function to find the constancy of use of any note(key) on that standard keyboard.

This activity is both a fun, and effective means for students to practice their proficiency while making the theories more relatable, concrete, and understandable.
