Welcome to my acoustic music tools here at tools.markabout.com. The tools are designed to aid in your acoustic guitar playing, but are applicable to other fretted string instruments as well. The free-to-use tools run directly in your web browser, and require the browser's built-in JavaScript.

Update for October 2020:  I've recently removed the CapoCalc tool, and done some general cleanup. Otherwise, no significant changes in a long time. I still have some website visitors, so I keep the site up.   ~Mark
