The diagrams
Every neck, keyboard, staff and chord box on this site is drawn by Everyfret’s own software, from the notes themselves. None is drawn by hand, and none is generated by AI one page at a time.
The software was written with the help of AI coding tools. More than a thousand automated tests check what it draws before anything is published, across every key, scale and tuning the site offers.
One of them, drawn by that software
A, A♯, B, C, C♯, D, D♯, E, F, F♯, G and G♯, then A again.
This is the keyboard from the first lesson of the guitar course, drawn here by the same code that draws it there. Nothing about it is written by hand for this page.
The words
The lessons, the text on each page and the books were drafted with the help of AI. A person checks each lesson, and a lesson that has not been checked yet is kept out of search engines until it has been. AI can state something confidently that is not true, and a careful reader can still miss it, which is why each page says how it was made.
Where mistakes can hide
Dates and names are the details most likely to be wrong, because even the players’ own interviews disagree about them. Where two good sources disagree, a page shows both rather than choosing quietly.
Who is responsible
Everyfret is responsible for everything published on this site and in its books.
