This paper purposes to attempt a new description of music through seeing and listening to the ``nature``, the main motto of the eighteenth century. First, I try to find the common ground from both fields of garden and music in terms of ``landscape`` and ``soundscape``, resulting in the definition of landscape for listening not for seeing. The music of the early eighteenth-century England can be considered as emblematical, while the music of the mid eighteenth-century England as naturalistic. Further, this paper attempts to view a new change of late eighteenth-century music in view point of picturesque. This paper introduces picturesque taste emerged in the mid eighteenth century, introducing William Gilpin`s use of the term, Gilpin`s picturesque garden theory emphasized on ``variety`` in composition of landscape; and his garden chooses to cooperate artificial elements into pure nature. And this paper redefines the meaning and function of music as comtemporary social and cultural phenomenon.
