Defining key centers with rhythm

Let’s say you have two chords, G7 and C. According to Western classical theory, these two chords establish that you are in the key of C. The G7 is tense and unresolved, and it makes you yearn for the calm stability of C. Music theory resources are full of language about how dominant seventh chords …

Music Theory Songs

Ashanti Mills from my Patreon had a brilliant idea. He said, hey, you know how you combined interviews with Toni Blackman with hip-hop songs to explain hip-hop pedagogy?

The Groove Pizzeria

For his NYU music technology masters thesis, Tyler Bisson created a web app called Groove Pizzeria, a polyrhythmic/polymetric extension of the Groove Pizza. Click the image to try it for yourself.

Making chords from scales

Jazz musicians think of chords and scales as two different ways of looking at the same thing: a group of pitches that sound good together. If you organize the pitches sequentially and play them one at a time, you get a scale. If you stack them up and play them simultaneously, you get chords. Here’s …
