This textbook aims to enable choir singers to handle musical notation as they once learned to handle written characters: they should learn to read music and develop their ear. At the same time, they should acquire knowledge and gain insight into musical contexts that, when combined, are essential for meaningful music-making. "Singing from Sheet Music" is a teaching resource designed to learn sight-singing. It primarily targets members of amateur choirs in schools, churches, and community organizations. With a total of 1,000 practice examples, Kolneder's textbook not only teaches sight-singing but also provides comprehensive knowledge and insights into musical relationships. It is a foundational course for every choir singer.
