Taiwanese, originated from South-Fujian dialect, is a tone language, so there has been a great mount of folksongs until now. Musicians in the 20th-century began to write new songs which were mainly for a massive middle-class amateur market. After the World War II, the composers Lu Chuan-sheng and Kuo Chih-yuan, who had studied music in Japan and returned to Taiwan, tried to compose art songs in Taiwanese, but only a few qualified works were retained. Because of the complicated political and social context during 1960-1990, no more serious songs in Taiwanese were composed nearly within 30 years of time. The vocal compositions were completely in Chinese language then. In the 1990s, more and more music teachers, singers and composers were gradually interested in Taiwanese poem and literature, and tried to write art songs again. In the early 21st century, many concerts with the new song repertoires were held, and miscellaneous songbooks were published. These Taiwanese serious songs appear in different styles: in folksong-like style with a simple harmonic accompaniment, in classic/romantic style, or in modern style using contemporary compositional techniques. Recently, we find the vocal composition in Taiwanese not only solo songs with piano accompaniment, but also in chamber music, in orchestral music, and in the style of speech-song, etc.. In the nearest future, the Taiwanese art songs will develop their own richness and beauty.
