“Most other common progressions in rock and pop music are variations (more or less) of I-IV-V, such as: I-IV-I-IV-V-IV-I. Here’s a list of some very common chord progressions you can find in songs: I — vi — IV — V I — V — vi — IV I — V — IV — V I — IV — V iii — vi — ii — V I — IV — I — V I — V — ii — IV I — vi — ii — V I — V — vi — iii I — iii — IV — V You can just pick a key and play any of these chord progressions and it will sound great. More complicated progressions include, for example, iii-vi-ii-V-I (in which diatonic chords are played on the 3rd, 6th, 2nd, 5th and tonic of a Major key), I-vii-vi-V, and iii-vi-V-I, among others. Notice that in all of these cases, movement is established away from some tonic chord (usually to some subdominant chord) and then, passing through a dominant chord (usually the V chord), a cadence is produced as the progression resolves back to the tonic.”
