About this site

Hayes Music is a set of guides and practice tools for music students from Year 7 to Year 13. Each year group has its own page with the topics you study that year. The first full guide is the A-level guide to harmonising Bach chorales, with the Chorale Checker.

The site supports your learning between lessons. It does not replace your teacher, and your teacher's judgement is always final.

Your privacy

• You do not need an account, and the site does not ask for your name or any other personal details.
• The Chorale Checker grid runs entirely in your browser. What you type into it is not sent anywhere unless you ask for full feedback.
• When you upload a photo or ask for full feedback, the photo or your harmonisation is sent to Anthropic, the company that makes the Claude AI, to be read and marked. It is processed and then discarded: this site does not store it. Under Anthropic's commercial terms it is not used to train its models, and Anthropic keeps API data only for a limited period for safety monitoring. Photos are shrunk and stripped of hidden details, such as location, in your browser before they are sent.
• Do not put your name or other personal details in a photo.
• The site does not use advertising or tracking cookies.
