Acoustic Music Webtools
ChordSpell ChordMatch CapoCalc Tablature Site Map Author


Welcome to the home of my acoustic music web tools at The tools are designed to aid in your acoustic guitar playing, but most are applicable to electric guitar and mandolin as well. The free-to-use tools run directly in your web browser using the built-in JavaScript.

Update in January 2016:  Due to lack of time and changing priorities, I haven't made substantive updates to these tools for about 10 years. I've considered taking the site down, but I'm actively using the domain for other purposes and it costs me nothing incrementally to keep Acoustic Music Webtools here. Further, this site still gets a couple thousand page loads each year, and I occasionally still receive email comments or questions about the tools. So it's still up, plugging away.  ~Mark

  • ChordSpell -- Name the chord formed by notes you select, with optional fretboard entry and alternate tunings.
  • ChordMatch -- Find chords that contain a given melody note (useful for "figuring out" songs).
  • CapoCalc -- Determine where to set a capo to match the key of another player.
I hope you find these tools interesting and helpful. By the way, this site is strictly non-commercial with no advertising banners, popups, or traded links. Old school.
