The "Cheerful Viola" is a viola school for children. It is primarily aimed at students who want to start directly with the viola without going through the violin first. Those who have already played the violin and use this school as a "transition school" may skip certain pieces or even start with volume 2. As with the "Cheerful Violin," the focus is on the joy of learning. A stylistically diverse selection of songs and pieces from classical music and folklore motivates students to make music, while short texts provide interesting information about the viola, music, and its composers. The viola is treated as both a solo and an accompanying instrument, with targeted training in "listening" and "counting" of lower and middle voices. The notation of many song and second voices in the treble clef, along with examples for trio and quartet, encourages playing together with friends.
