This new lesson available here will explain in very basic terms how you can figure out what chords fit in any key. This is a really important skill every guitarist should be able to apply. Learning to work out chords in a key will allow you to do things like:
- Write your own song or chord progressions
- Jam with other guitarists and other musicians
- Work out chords and scales used in songs
The lesson explains a simple formula you can follow and gives a few exercises to help you get used to it.
