The service

Free Scale Finder helps you compare a set of notes or a supported chord with a reviewed catalogue of scales. It is provided free of charge, without an account. The tool runs in your browser and does not upload your notes or audio.

The site is an educational reference, not a professional music service. It does not provide transcription, composition, recording, mixing, mastering, legal, financial or accessibility advice.

Accuracy and no warranty

The scale catalogue, spellings and chord rules are maintained carefully, but music theory has context-dependent conventions and software can contain errors. Results are possible interpretations, not guarantees. The tool is provided “as is” and “as available”, without warranties of any kind to the extent permitted by law.

Always use your ears and, where it matters, a qualified teacher or another reference. Do not rely on this tool for a performance, recording, exam or commercial decision without checking the result.

Acceptable use

You may use the tool for personal learning, teaching and study.

You may not:

  • attempt to disrupt, overload or gain unauthorised access to the site or its hosting;
  • scrape or republish the site in a way that misrepresents it as your own service;
  • use the site to distribute unlawful, harmful or infringing material;
  • remove attribution from the source code or third-party notices where a licence requires attribution.

Content and licences

The site’s text, design and original source code are part of the Free Scale Finder project. The project uses open-source dependencies, including the Tonal music theory library under the MIT licence. Those components remain subject to their own licence terms.

You are responsible for any notes, chord symbols or other content you enter. Do not enter material you do not have the right to use.

Limitation of liability

To the extent permitted by law, the project and its contributors are not liable for indirect, incidental or consequential losses arising from use of the site, including lost work, lost opportunities or reliance on an incorrect result. Nothing in these terms excludes rights or liabilities that cannot be excluded by law.

Availability and changes

The site may change, be unavailable or be discontinued without notice. Features may be added or removed. These terms may be updated; the date at the top of the page shows the latest revision. Continued use after a change means you accept the revised terms.

Contact

Questions about these terms can be sent through the contact page. If no public contact address is shown there, this build has not yet been configured with a monitored inbox.

These terms are a plain-language summary for this build. They are not a substitute for legal review before a public commercial launch.
