These notes by Feuermann are culled from several spiral notebooks that the cellist carried with him on his concert tours around the United States between 1940 and 1942. The notes were written in German and English-mostly in the latter, as time wore on.
An attempt is made here to balance topicality with the sequential order that the notes were given by the cellist. Obviously there is some repetition. But this can be borne, especially since there are always slightly different nuances given by Feuermann to each of the topics.
Of necessity, some rewriting has been done to correct obvious errors in grammar or word choice that might obscure meaning. Occasionally a word or phrase has been added in order to maintain connection between ideas. And since these are occasional fragments written here and there, limited restructuring of paragraphs was necessary.
