Open software for music theory

Welcome to my project website.

LenMus is a free open software project, committed to the principles of open source software, free education, and open access to information. It has no commercial purpose.

It is a personal project, to learn and for fun, that I do in my spare time, so do not expect new features every few months! . Sorry!
