Lydian Gravity
Full-Stack Modal Songwriting Workspace
Problem
Songwriters working with modal harmony need a structured workspace for sketching arrangements, saving ideas, and finding theory-aware next steps without leaving the creative flow.
Solution
Built an authenticated full-stack songwriting app with a Next.js editor, saved song library, guided setup, section-based arrangement tools, modal chord and melody editing, browser audio preview, and FastAPI persistence and suggestion APIs.
Tuning
Modeled nested arrangements with typed frontend and backend contracts, added JWT-protected user-scoped persistence with SQLite and SQLAlchemy, and implemented deterministic modal suggestion logic for harmonic, melodic, rhythmic, and gravity-center prompts.
