Noticing harmony beneath the melody
Launch library · evergreen read

Melody usually draws the most immediate attention from a listener, but the harmony quietly supporting it, the chords moving steadily underneath, shapes emotional tone every bit as significantly, even if it happens to operate considerably more quietly overall, attention harmony rarely receives on its own, despite doing so much of the actual emotional work.
Training an ear to notice harmonic movement, a chord shifting rather unexpectedly beneath an otherwise familiar melodic line, often explains why a particular moment in a song ends up feeling genuinely surprising or moving to whoever is listening closely, moments a purely melodic ear, however experienced, would likely pass straight over without noticing.
This particular kind of listening takes real practice to develop properly, but even a general awareness that harmony is doing quiet emotional work considerably deepens appreciation for songs a listener may already believe they know very well indeed, songs a listener may have already played many times without ever quite hearing this particular layer.
