Characteristics of art songs:

Art songs are a musical genre that combines poetry and music to simultaneously accomplish the task of artistic expression. Its name comes from the romantic music master Shu It was established by Bert's works and became an independent type of song genre. It combines beautiful melody and human voice, the two most universally appealing musical elements, making art songs highly expressive and appreciative. It is a unique form of artistic expression of romantic music in the 19th century.

Extended information:

Art song tunes, including singing parts and accompaniment parts, are usually accompanied by piano. The significance of this accompaniment part is not just for the singing part. Instead of providing a general foil, a variety of expression techniques in musical art are used to perfectly interweave accompaniment and singing to form a musical tune texture to jointly create a complete and rich musical image.

Art songs are mostly performed by solo performers. But the voices are widely used, including soprano solo, coloratura soprano solo, mezzo-soprano solo, tenor solo, baritone solo, and even bass solo and alto solo. In addition, there are chorus and a few duets.
