Abstract
In this paper, we analyze and study about the incidental music focusing on the Frederick Delius's choral music without instrumental accompaniment. Incidental music refers to music composed for a play, often played between acts or as background music. Typically, incidental music is discussed within the realm of classical music, but historically, it has evolved into background music for various media. Additionally, incidental music is predominantly instrumental rather than vocal or choral. However, Frederick Delius expanded the scope of incidental music to include choral elements. Delius's efforts opened new possibilities for incidental music, enhancing the integration of drama and music. His works transcend mere background music, enriching the atmosphere and emotions of the play. This provides the audience with a more immersive experience and elevates the artistic value of incidental music. Frederick Delius's unaccompanied choral work, "Two songs to be Sung of a Summer Night on the Water" is characterized by their lack of lyrics and melodic and harmonic texture, making them even more suitable as incidental music.
