“With music, art abandons the immersion of the spirit in a tangible, visible, and directly present shape… it made the inner life as such, and subjective feeling, something for apprehension by the inner life, not in visible shapes, but in the figurations of inwardly reverberating sound… This sensuous stimulation of our hearts can be produced by music alone.”
From Bach to Gospel, Protestantism puts more into music than visuals. It has to do with the inward emphasis.
