Dowlding in the book Beatlesongs Longwinded notes: Color patterns offer clues about the band's gradual fracturing as each member became more independent. Red stalks (signifying jointly written songs) decrease in the second half of the timeline; the split-color bars give way to solid bars of a single color.
