Music is made up of a large number of individual sounds, and is either a single melody or a part-song.

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

Music has to do with sounds, so we need to find them somewhere and it is preferred to find musical ones. You have two sources for sounds: noises, which always tell you something — a door cracking, a dog barking, the thunder, the storm; and then you have instruments. An instrument tells you, 'la-la-la-la.' Music has to find a passage between noises and instruments. It has to escape. It has to find a compromise and an evasion at the same time; something that would not be dramatic because that has no interest to us, but something that would be more interesting than sounds like Do-Re-Mi-Fa...

Music is the space between the notes.

Music is the cup which holds the wine of silence. Sound is that cup, but empty. Noise is that cup, but broken.

There is very little dispute about the principal constituent elements of music, though experts will differ on the precise definitions of each aspect. Most central are 'pitch' (or melody) and 'rhythm'... next in importance only to pitch and rhythm is 'timbre', the characteristic qualities of tone.

Music is motion from nonrest to rest.

Music and silence... combine strongly because music is done with silence, and silence is full of music.

Music is everything that one listens to with the intention of listening to music.

It appears to me that the subject of music, from Machaut to Boulez, has always been its construction. Melodies of 12-tone rows just don't happen. They must be constructed....To demonstrate any formal idea in music, whether structure or stricture, is a matter of construction, in which the methodology is the controlling metaphor of the composition...Only by 'unfixing' the elements traditionally used to construct a piece of music could the sounds exist in themselves--not as symbols, or memories which were memories of other music to begin with.

Music is the melody whose text is the world.

Music is a mysterious mathematical process whose elements are part of Infinity. … There is nothing more musical than a sunset. He who feels what he sees will find no more beautiful example of development in all that book which, alas, musicians read but too little — the book of Nature.

Music is any sound you want to go on and on.
