The Anatomy of Music is a beginner’s guide to the DNA of sound. In this class, we’ll strip away the intimidation of traditional music theory and explore how rhythm, melody, chords, and structure work together to create the songs you love. Whether you’re a songwriter or composer looking to add to your composition toolbelt or just an avid music fan who wants to gain a deeper understanding of the science behind your favorite tunes, come and experience the living, breathing wonders of music in this approachable six-week course.

The KPCU Song Lab is a guided, collaborative workshop led by local musician Drea Marilyn that’s designed for songwriters and musicians to bring their works-in-progress into a live, communal environment. Part feedback session, part low-stakes acoustic jam, the Song Lab is where your songs find their missing pieces. Need a fresh set of ears on a bridge? Or perhaps you’ve always wondered what your piano ballad would sound like with a lead guitarist. The Song Lab is your space to experiment, iterate, and play.

How the "Lab" Works: 

1. The Pitch: As a songwriter, you will present your song-in-progress, then explain what you have so far and what specific kind of feedback you're looking for (e.g., "I have a verse and chorus, but I’m stuck on the transition").
2. Feedback: The group offers constructive, guided feedback on the writing itself.
3. Optional Jam: You, the songwriter, may invite the other musicians in the room to jump in for a quick jam with guided support from the instructor.
4. The Goal: "Let's hear this with a bass line," or "Can someone try a harmony on this line?"
5. The Result: You get a real-time "demo" of your song’s potential and an experience in collaboration.
