i've quite of kinda hearing these musical terms so much recently, especially when reading some reviews.
So what i know about them is that Harmonic is about harmonies and layering of music, Rhythmic is about beats and Melodic is about melodies and tones(?)
How do you define them when someone says "this song is too melodic/harmonic/rhythmic"
(can you get my drift

)
So what are their differences? Similarities?
Can they go hand on hand on a single piece of music? Can one exist in a song without the other two?
Examples?
