Answer 1

Hey wassup

The main components are: these 4

Rhythm....Earlier composers used one time signature but today, we not only use the usual two, four, six, but also, in five, seven, eleven, and thirteen time signatures

Melody

Harmony....Polychords which require the use of 1,3,5th & Polyharmony which is 2 melodies played at the same time based on two different triads.

Tonality....

Answer 2

The main components of music are -

notes & rhythms.  The length of the notes becomes the rhythm, and that combined with the actual notes is the melody of what you are playing.

It does go farther with using harmony and such, but that only comes into play if you have one more than one instrument / voice, etc that play together.
