# SIGMA MUSIC > SIGMA MUSIC is a curated digital music distribution platform for independent artists across Spanish-speaking Latin America and Spain. Artists complete a short training academy, unlock a personal artist workspace called SIGMA OS, and, after human review, distribute their music to Spotify, Apple Music, TikTok, YouTube Music, Amazon Music, Deezer and 470+ platforms worldwide. SIGMA MUSIC is not a bulk "upload and forget" tool. It guides each artist through release preparation, metadata, audio quality, cover art, credits, ISRC codes, release timing, rights and quality checks, before professional distribution. The public website is in Spanish and focused on the needs of independent artists in Latin America and Spain. The operating company is SIGMA MUSIC, S.L., based in Barcelona, Spain. The artist journey has five steps: (1) create a free account; (2) complete SIGMA ACADEMY, a short set of video lessons and quizzes that teach release fundamentals; (3) get certified; (4) unlock SIGMA OS, a workspace with performance benchmarking, an AI artist assistant called "SIGMA Agent", a press-kit builder, campaign planning, opportunity matching and fan-base signals; (5) submit a release, which SIGMA reviews by hand before distributing it. Pricing is a one-time payment per release, with no subscription. ## Core pages - [Home](https://sigmamusic.net/): Overview of SIGMA MUSIC, the artist journey, supported platforms and pricing. - [Create an account](https://sigmamusic.net/register.php): Free artist registration to begin the process. - [SIGMA ACADEMY](https://sigmamusic.net/academy.php): The required training (video lessons and quizzes) artists complete before professional distribution. - [SIGMA OS, the artist workspace](https://sigmamusic.net/artist-hub.php): The tools unlocked after certification, including benchmarking, the SIGMA Agent AI assistant, press kit, campaigns, opportunities and fan-base signals. - [Blog](https://sigmamusic.net/blog.php): Practical guides for independent artists on distributing music, Spotify, royalties, marketing and release strategy. ## Optional - [Legal notice](https://sigmamusic.net/aviso-legal.php): Company identification for SIGMA MUSIC, S.L.
