I built a 3D Web App for Guitarists in 6 days with Cursor

A developer created an interactive 3D web application in 6 days to help guitarists learn fret note locations on the guitar neck. The app uses real-time audio detection to identify played notes and gamifies the learning process with visual feedback. Built with Next.js, Spline 3D for the 3D interface, and Web Audio API for note detection, the project demonstrates rapid development using Cursor AI coding assistant. The app features adjustable note duration, background music, virtual fretboard display, and works with both electric guitars and acoustic guitars via microphone input.
