Terms of use
Use these resources as learning references and adapt your practice to your own instrument and experience.
Educational references
The library supplies educational diagrams and files, not personalized instruction. No fingering, hand stretch or difficulty rating is implied by a diagram. Stop a physical exercise that causes discomfort and seek suitable guidance.
Accuracy and corrections
We aim for consistent formulas, spellings and downloads but errors and differing conventions are possible. Verify material before relying on it in teaching or publication. Report a specific discrepancy through the contact page so it can be checked.
File permissions
Use downloaded files according to the license displayed on the reference and in its download pack. Preserve attribution and applicable notices. The file license does not grant rights to third-party brands or imply endorsement.
Availability
Files and pages are supplied as available. The library may be corrected or reorganized over time. Keep your own copy of files you need for a lesson or performance.
