Open Chord is built on open source software written by other people. Each component below remains the property of its authors and is used under its own licence. We are grateful to everyone who made their work available.
If you believe a component is listed incorrectly, or that an attribution is missing, please write to us at oaktechnologiesfze@gmail.com and we will correct it.
Every guitar note you hear in Open Chord comes from this soundfont. The samples are delivered through midi-js-soundfonts by Benjamin Gleitzman, which distributes the FluidR3 collection under the Creative Commons Attribution 3.0 licence. The original author released the soundfont under the MIT Licence. We give attribution under both.
Frank Wen asks that software bundling Fluid should not lock the soundfont behind payment or restrict access to its instruments. Open Chord is free, has no paywall and no premium tier, and every sound in the app is available to every user.
