The reference to Jessica Wiskus' paper (footnote 2) is somewhat puzzling: unless I am mistaken, she does not quote Free Composition (which, in addition, is not a translation of the 1935 edition of Schenker's book), she merely refers to a paper by Lee Rothfarb, "Energetics", The Cambridge History of Western Music Theory, Th. Christensen ed., CUP 2002. This paper, in turn, mentions Free Composition only once in passing and more often quotes Schenker's Harmony and Counterpoint. Clarification would be useful.
