## Questions

### Is the major and minor key signature reference really free?

Yes. Download either paper size without creating an account. You may print, photocopy, and distribute it to your students under the Arco printable licence.

No. It is a concise reference or worksheet. Instrument setup, body comfort, repertoire context, and fingering choices still need musical judgment.
