Today found very good example which shows how popular music “simple” is. Many songs uses this common chord progression (I, V, VIm and IV).
On next video it is: D, A, Bm, G. (All songs transposed in one key). Other version: C-G-Am-F, A-E-F#m-D, etc…
So, if you want to create new hit:
1) Compose new melody which match notes in this chord progression.
2) Then just sing this melody with some words and play the chords. 🙂
