- Select a musical instrument to build. Students in 6th grade or higher should build a tunable instrument involving string, water, or air waves.
- Sketch a design.
- Obtain a Peer Review before you begin building your instrument.
- Build your instrument. Tune it to at least one octave (plus one) in a pentonic major scale, such as C, D, E, G, A, C.
- Document the process (sketch, photos, videos).
- Submit a brief demonstration of your instrument.
