Terms of Use
Plain terms for reading, quoting and sharing what you find here.
Using the library
You may read, print and share links to the library for personal, educational and non-commercial purposes. Please do not use the library in a way that damages it, overloads it or interferes with other readers.
Text
The written entries, articles and glossary are © 2026 Mary Aguirre — Atlas Musical. You may quote short excerpts with clear attribution and a link to the page you quote. Reproducing whole entries or republishing them elsewhere requires written permission; write to [email protected].
Images
Photographs belong to their authors and are published under the licences listed on the Image Credits page. If you reuse an image, follow the terms of its own licence, including attribution, and not these terms.
Accuracy and limits
The library is prepared with care and cites its sources, but it is an educational reference and is provided as is. It is not professional advice. Information about instrument care is general; for repair, restoration, health questions related to playing, or valuation, consult a qualified professional.
External links
Citations link to third-party websites. We do not control them and are not responsible for their content or availability.
Changes
These terms may be updated from time to time; the date below shows the latest revision. Continued use of the library after a change means you accept the updated terms.

Questions about these terms can be sent to [email protected].
