Each 'someone' creates their own 'something'. However, the 'somethings' of those 'someones' are all the same. And ultimately, those 'someones' are also 'someone'. But each 'someone' produces a unique sound. The combination of those sounds is like the 'something' created by those 'someones'. The process of blending each person's unique sounds to create a melody is another act of creation.
