Use this application to see what chords belong to which number in a key.
Here at beginner, only the keys of C and G are available. This is partly down to that these are the keys of the songs you learn in the beginner course. Mainly, however, it’s because these are the two keys that use almost only open position chords.
The main goal with the SWS is to see what number each chord gets. By thinking of chords as numbers (roman numerals), you lay the foundation for understanding music.
