“Music is the beating that puts hearts in harmony.”

Small Houses: Their Economic Design and Construction (1922)
Context: When, in architecture, one uses a fixed unit and combinations of it, to produce harmony, the effect should be most striking and apparent... as it is in music by the measured beat and in poetry by the cadence and rhythm.<!--Ch. II

Context: The harmony of music exists equally with the harmony of movement in nature.
Man has not invented the harmony of music. It is one of the underlying principles of life. Neither could the harmony of movement be invented: it is essential to draw one’s conception of it from Nature herself, and to see the rhythm of human movement from the rhythm of water in motion, from the blowing of the winds on the world, in all the earth’s movements, in the motions of animals, fish, birds, reptiles, and even in primitive man, whose body still moved in harmony with nature….. All the movements of the earth follow the lines of wave motion. Both sound and light travel in waves. The motion of water, winds, trees and plants progresses in waves. The flight of a bird and the movements of all animals follow lines like undulating waves. If then one seeks a point of physical beginning for the movement of the human body, there is a clue in the undulating motion of the wave.
