Taming the Guitar AND Functional Programming!

on YouTube ↗14m

" summary

A small TypeScript app implements an improvisation helper that connects Web Audio nodes into a composable pipeline and plays sine tones in the browser. It applies fp-ts-style functional patterns (reimplementing Option/Maybe and Either/Left/Right via TDD) to chain guitar → effects → amp, propagate None for missing chord dictionary entries, and validate user input to log errors or produce frequencies. The repository and tests demonstrate the approach end-to-end.
