Find songs to play with the chords you know
Finds songs a guitarist can play with the chords they already know, from Fretwork's free library of 87 public-domain folk, gospel, blues, campfire and Christmas songs.

guitar_level_check
Check a guitarist's level
A quick self-assessment that places a guitarist on Fretwork's 10-stage learning path (Stage 0 Getting Started to Stage 9 Artistry) from yes/no answers to up to nine questions about what they can already play, and says what to learn next. The questions build on each other, so answers are read in order up to the first "no". Called with no answers, it returns the nine questions.
