That chord progression! Pabotiro ni JF yan! Maririnig mo sa Scar Tissue, By The Way, Tear, Dosed, Dani California, Slow Cheetah, Under The Bridge. Sa solo work nya andami din, Unreachable, Omission, Second Walk, Wednesday Song, Unchanging, Your Pussy's Glued at marami pang ibang variation. Iba-ibang key lang yung ginamit nya pero ganun parin yung effect. Ang malupit dun kaya nyang humugot ng ibatibang melody based sa chord progression na yun pero hindi magkakatunog! A very good example is The Past Recedes at I'm Around! Pareho ng chords pero they are two completely different songs! May mga kanta din sya na magkakatunog yung vocal melody BUT the feeling of the song is different! Example yung Moments Have You at Interior Two. The genius of John Frusciante!!
