This work, based on the author's 1981 doctoral thesis, presents us with by far the most extensive and detailed study of the early raga system yet attempted ... unique and startlingly effective contribution ... Author and publisher have gone to considerable lengths to ensure the quality of text and presentation. No matter how difficult the arguments become they are always presented as clearly as possible, without succumbing to over-simplification or the avoidance of difficult issues. The text is free of typographical and other errors to an astonishing degree, and music examples seem to have been checked with similar thoroughness ... There can be little doubt that this work will come to be regarded as a classic in its field: indeed, a milestone not only in Indic musicology but in historical ethnomusicology as a whole.
