Open Music License (OML)

A fair, transparent, and enforceable open-source license for music production assets.

What is OML?

The Open Music License (OML) is a dual-tier licensing framework designed specifically for music producers, beatmakers, and audio creators who want to share their work openly while maintaining fair compensation for commercial use.

Perfect For

  • Samples and one-shots
  • Loops and beats
  • Stems and multitracks
  • MIDI files and sequences
  • Production templates
  • Sound design assets

Why OML?

Traditional open-source licenses (MIT, GPL, Apache) weren't designed for music. Creative Commons licenses lack specific provisions for royalties, sampling rights, and revenue thresholds. OML bridges this gap with:

Clear Attribution Requirements - Specific formats for metadata, credits, and promotional materials
Fair Revenue Threshold - Free for personal and small projects under $1,000 annual gross revenue
Transparent Commercial Terms - Reasonable royalty structures for professional use
Music-Specific Provisions - Addresses sampling, stems, derivatives, and sync licensing
Legally Enforceable - Professional language with clear dispute resolution
Creator-Friendly - Protects your work while encouraging collaboration

Three License Types

🆓 OML-Personal (Free Tier)

For hobbyists, students, emerging creators, and small-scale projects:

  • Use, modify, and distribute freely
  • Monetize up to $1,000 gross revenue per year
  • Attribution required in all uses
  • No exclusive rights granted

💼 OML-Commercial (Royalty Tier)

For professional releases, sync licensing, and commercial projects:

  • Unlimited commercial usage rights
  • Fair royalty structures (percentage or flat-fee options)
  • Quarterly reporting and payment terms
  • Enhanced attribution requirements
  • Sublicensing provisions for derivatives

🎬 OML-Sync (Synchronization License)

For film, television, advertising, video games, and audiovisual content:

  • Master use and synchronization rights
  • Project-specific licensing terms
  • Professional delivery requirements
  • Detailed territory and media specifications
  • Flat fee payment structure
