    About the Project

    Cadenza App is a comprehensive suite of musical tools designed by musicians, for musicians. The platform provides a collection of interactive instruments and utilities that help musicians explore new sounds, analyze their favorite tracks, and experiment with musical ideas in an intuitive environment.

    The tool suite includes features for sound exploration, audio analysis, and creative experimentation. Built with a focus on accessibility and ease of use, Cadenza App lowers the barrier to entry for musicians who want to incorporate technology into their creative process. The project demonstrates the intersection of music theory, audio processing, and modern web technologies to create tools that genuinely enhance the creative workflow of musicians.

    I was experiencing burnout from excessive work when I remembered my beginnings as a musician, where I was deeply interested in music theory. To relieve the stress of programming, I started coding something again, but for pleasure rather than necessity. That's how Cadenza was born — a free and open source software for learning music theory. The project continues to grow with new features as I encounter different needs in my own musical career, making it a constantly evolving tool that serves both my creative journey and the broader musician community.
