SOPP499: What are the numbers at the beginning of the piece for French harmonium?
This question was sent by Joanna, and she writes:\n \n\u201cDear Vidas\nI bought a copy of Vieux Noel by Cesar Franck from your website. I wanted to ask you something which I do not understand. What are the numbers at the beginning of the piece...number 1, number 4 and number 0 in a circle?\nRegards and thanks\nJoanna\u201d
