## Pythagoras and the Ratios

Icon:

Pythagoras and his cousins want to win a music contest, but first they must figure out how to play their instruments in tune, something that's never been done before.

While trying to fix the problem, Pythagoras makes an important discovery--notes that sound pleasant together have a certain mathematical relationship. When Pythagoras applies this ratio to his cousins' pipes and lyres, the result is music to the ears.

Watch how MacPhail Center for Music’s partnership with Ascension Catholic School in North Minneapolis brings classical musical education to children who might not otherwise have the opportunity.

This program, which began in 1989, serves as a model for more than 90 other community partnerships that bring musical education to many diverse communities throughout the state.

## Scale City | Proportions and Music in the Real World

Icon:

In this video—through footage of the calliope aboard the Belle of Louisville, a church pipe organ, and various instruments at a recording studio—students are introduced to the mathematical concept that the length of a musical pipe or a string has a proportional relationship with the sound it produces.  In the accompanying activity, stringed instruments are used to demonstrate the concept presented in the video. This resource is part of the Math at the Core: Middle School Collection.

## The Lowdown | A-Rhythm-Etic

Rock out to a musical demonstration of math involved in constructing rhythms from groups of beats in this video from KQED. In the accompanying classroom activity, students consider how the note durations comprising a measure in 3/4 time relate to fractions that sum to 1. Then, they create and perform their own 3/4 measures comprised of quarter, eighth, and sixteenth notes. To get the most from the activity, students should have experience adding fractions with unlike denominator. This resource is part of the Math at the Core: Middle School Collection.
