Editing In C (section)

===Reception===
''In C'' was well-reviewed by critics. For ''[[Glamour (magazine)|Glamour]]'', Janet Rotter dubbed the composition "the global village's first ritual symphonic piece" and raved, "Terry Riley has not yet reached the mass concert audience that [[the Beatles]] have, but he has written in his own way to that audience".<ref>Rotter, Janet. "Sound", ''[[Glamour (magazine)|Glamour]]''. February 1969. 66.</ref> In ''[[Sound & Vision (magazine)|Stereo Review]]'', David Heckman admired the effect while disliking the result, "In C produces, over the course of its forty-three minutes, a vague hypnotic effect, that is doubtless related to the repeated C, hammering away incessantly through the musical fabric. Isolated motives, bits and snatches of themes, and a kind of ''[[Klangfarbenmelodie]]'' of individual pitches drift in and out of one's consciousness. Very nice, for a while, but ultimately wearing."<ref>Heckman, David. ''[[Sound & Vision (magazine)|Stereo Review]]''. March 1969. 103–4.</ref> Alfred Frankenstein revisited the piece with undimmed enthusiasm in his album review for ''[[High Fidelity (magazine)|High Fidelity]]'', "Terry Riley's ''In C'' is one of the definitive masterpieces of the twentieth century. It is probably the most important piece of music since [[Pierre Boulez|Boulez]]' ''[[Le Marteau sans maître|Marteau sans maître]]'', conceivably it is the most important since the ''[[The Rite of Spring|Sacre]]''."<ref>[[Alfred Frankenstein|Frankestein, Alfred]], ''[[High Fidelity (magazine)|High Fidelity]]''. February 1969. 104.
