{"type"=>"did", "value"=>"Throughout his notes on C.P.E. Bach, Schenker uses a particular labeling system, following the original German edition of the treatise. The Roman numeral refers to the chapter, all in the \"Zweite Teil,\" followed by either one or two different arabic numerals. The arabic numbers refer either to the segment, or \"Abschnitt,\" of which there are at most two within a chapter; the second number refers to the section, either within the chapter or within the segment within the chapter. The symbol \"§\" is used ubiquitously to refer to the section; otherwise, it refers to the segment. For example, \"VI/2, §2\" refers to \"chapter 6, segment 2, section 2.\" In many cases Schenker's markings are directly quoted, and are put in quotation marks. \"S\" refers to \"Seite,\" or page number in the German edition. \"Kap.\" refers to \"Kapitel,\" or chapter. In other cases, Schenker labels the section based on the topic, such as figured bass numerals \"5/3\" or \"6/4,\" etc."}
