Jean,

Respectfully, it's not a matter of how one looks at it, there are four components of music: Pitch, Duration, Volume, Tone, and, arguably, a fifth, Sonance. You are describing aspects, not components, of music. Pitch and duration make melody. Rhythm is created by the duration of the pitch. Multiple pitches played concurrently make harmony. Any pitch has, by nature, a tone and a level of volume.

Any aspect at all of music contains all four of the components. There is no single note that can be played without pitch (whether definite or indefinite), duration (except for God's note which has no beginning or end), volume (either it vibrates at some intensity, or it doesn't), or tone (even generated so-called "pure" notes have tonal quality).

Tom,

You can make a car or you can drive it. Neither are components of the car. To make music you manipulate the four components, to listen to music you receive said components.

All the Best,
Mike
