When you are learning guitar the use of software often makes the learning curve less steep. The good news is that much of the guitar software available on the net is free. There are many musicians developing their own guitar software and sharing it with others. Software for learning chords and scales, guitar effects, and free guitar tuners are all available for download. Because the internet is changing all the time, websites go up and websites go down, I will just give you the names of the software I have found and leave you to do a search for the latest version.
KD’s Guitar Utilities developed by Kent Dalton, this package is a group of utilities that help you in guitar fretboard learning. They began life as a basic set of chord and scale diagram generators and is offered as copyrighted freeware at the moment. These utilities generate scale diagrams, generate chord diagrams, give you chord names based on fingering, generate arpeggio diagrams, determine chords that fit into a given key or scale, and determine scales that fit into a given chord progression. The programs support a range of custom tunings. If a scale or tuning is not known to the tools, you can input custom scale patterns and tunings.
