These shapes can be moved up and down the fingerboard to produce a minor chord in any key. The root note will dictate what minor chord it is. Note we need to use a first finger barre again for some of these.
Here is an example of a minor chord progression using barre chords. Note the reggae-style strum pattern (each strum is on the off-beat). This type of progression is used in songs such as 'I shot the Sheriff' by Bob Marley.
