The bases of music are rhythm and harmony. Rhythm is ordered recurrence in time... As the planets move around the sun, they repeat their orbits periodically; thus there is already a primitive kind of rhythm in their motion. ...Harmony ...can be considered a special kind of rhythm. ...pure musical tones are produced when the vibrations are... periodic or... repeat themselves regularly in time. Two tones harmonize if their intervals of repetition are in rhythm—or, in mathematical language, if their periods are in proportion. Kepler... in the third book of Harmonice mundi... attempted to make other... related, connections between musical harmony and mathematical proportion.

Rhythm includes metre, but metre is a relatively small part of rhythm.

Music is the art of sounds in the movement of time.

Music is motion from nonrest to rest.

Maybe it is because music is about as physical as it gets: your essential rhythm is your heartbeat; your essential sound, the breath. We’re walking temples of noise, and when you add the tender hearts to this mix, it somehow lets us meet in places we couldn’t get to any other way.

Music and rhythm find their way into the secret places of the soul.

[T]he rhythm of music, akin to the human heart-beat and to the ceaseless change and motion, which is the basic fact in all life, apeals at once to our own physical vitality.

That musical time is a way of like creating a rhythm within the piece. And it was an amazing experience for me to see how when lines, directional lines, went through forms -- how forms, if moved to fit within the ratio, to hit the points. Like in other words, if an arm flies out, it goes to the point. Suddenly there's this like visual kind of connection between the forms, and it fits like, clicks like pieces of a puzzle, right into place…

Music is geometry in time.

To live is to be musical, starting with the blood dancing in your veins. Everything living has a rhythm. Do you feel your music?

Music is a kind of harmonious language.

I believe that the use of noise to make music will continue and increase until we reach a music produced through the use of electrical instruments which will make available for musical purposes any and all sounds that can be heard. Photoelectric, film and mechanical mediums for the synthetic production of music will be explored.

I take traditional rhythms and blend them with electronic instruments on my computer. For example, when I travel, I listen to all kinds of music. Now, I like listening to urban music. But urban music from Africa originates from traditional music. Only the instruments, the choice of electronic instruments, change. But the sound, the rhythm, remains the same.
