Naturally enough, the question whether Wölfli's music can be played is asked again and again. The answer is yes, with some difficulty. Parts of the musical manuscripts of 1913 were analyzed in 1976 by Kjell Keller and Peter Streif and were performed. These are dances – as Wölfli indicates – waltzes, mazurkas, and polkas similar in their melody to folk music. How Wölfli acquired his knowledge of music and its signs and terms is not clear. He heard singing in the village church. Perhaps he himself sang along. There he could see song books from the eighteenth century with six-line staffs (explaining, perhaps, his continuous use of six lines in his musical notations). At festivities he heard dance music, and on military occasions he heard the marches he loved so well. More important than the concrete evaluation of his music notations is Wölfli's concept of viewing and designing his whole oeuvre as a big musical composition. The basic element underlying his compositions and his whole oeuvre is rhythm. Rhythm pervades not only his music but his poems and prose, and there is also a distinctive rhythmic flow in his handwriting.
