I have just completed a page of (pretty) exhaustive charts for the Anglo concertina, as part of my tuition website the Supplementary Anglo Concertina Tutor - https://concertutor.wordpress.com/

The chords are here - https://concertutor.wordpress.com/fitting-chords-to-your-playing/chord-fingerings/.

There are 33 charts, covering 7 major keys and 6 minors. I hope they’ll be helpful to some people. Let me know your thoughts on the comments section of the page ( which I can’t find myself !).

The page is very lengthy, not at all compact, and perhaps a tad clunky. I may now go back and try to make it more user-friendly with my VERY limited Wordpress skills.

But in the meantime, Anglo players, I welcome your helpful comments.
