Because God put it there.
When hip-hops, blues rock and jazz bops it’s because of one thing.
Time is a created entity, put into three-dimensional existence by God. Without time, there would be no music – nothing to play against. Without time, music, and life, would have no improvisation, counterpoint, syncopation, harmony, diversity.
It’s all here for us, orchestrated by the hands of a loving, powerful and creative God.
