Email

Write to [email protected]. This is the only official contact address; we will never approach you from another domain or from a social account.

What to include

• the full URL of the lesson or chord page;
• the sentence or the figure you are querying, quoted;
• what you believe the correct reading is, and your source (textbook, chapter, or an authoritative link);
• for layout problems, your browser and device.

Response times

Errata are normally answered within three working days. Licensing and content requests take longer; we will acknowledge them first.

What we do not accept

We do not accept paid link insertions, guest posts, or "content partnership" placements, and we do not sell page positions. Mail of that kind is not answered.
