Book excerpt: In The Critical Editing of Music (1996) James Grier called Georg Feder's Musikphilologie (Darmstadt: Wissenschaftliche Buchgesellschaft, 1987) "the most important contribution to date" on textual criticism in music and "the only one that considers the full range of critical issues in editing" (Grier, p. 14). Pendragon Press's edition of Feder's Music Philology now makes available in English translation this essential, intellectually engaging but concise discussion of the complex and multi-faceted tasks in traditional scholarly editing of music. --
