Workshop #2: November 5th, 2022

9:30 am-1:00 pm PST

Building a Foundation Together with Inclusive Repertoire

Clinician: Larena Code

Online (Zoom)

In this actionable session, I’ll share step-by-step how I used the foundation of my Kodály training to gradually become a more inclusive, anti-bias music educator. Attendees will sing and play kid-tested activities and repertoire that validate multiple identities and center joy. We will also explore lesson segments that use guiding questions and thinking routines to support identity and diversity work within the Kodály framework. Additionally, participants will reflect on where they are on their own anti-bias journeys and identify what their next steps might be. Join in my ongoing journey as a white Kodály-inspired educator striving toward anti-bias praxis the Kodály Way.
