Music is an art form whose medium is sound organized in time. Common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts: tempo, meter, and articulation), dynamics, and the sonic qualities of timbre and texture. The word derives from Greek μουσική (mousike), "(art) of the Muses".... Music is like the 4 elements. Slow or fast like the wind! Clean or dirty like the earth! Smooth or hard like the sea and HOT like the fire! Music is also like us.
