Schoenberg took the twelve equal semitones from the chromatic scale and commanded that music be written in such a way that each of these twelve semitones be used before any one of them is repeated. If one of the semitones is repeated before all eleven others are sounded it might create an anchor for the ear, which could then recognize what was going on in the music harmonically. The twelve tone system guarantees the listener’s disorientation. Schoenberg proposed to erase the distinction between tonality and atonality by immersing man in atonal music until, through habituation it became the new convention. Then discords would be heard as concords. As he wrote, ‘The emancipation of dissonance is at present accomplished and twelve-tone music in the near future will no longer be rejected because of discords.’

Schoenberg was not exaggerating. He overcame 2,000-year-old conceptions of tonality, concord, and harmony to set discordance as the new standard for modern music. But once beauty in the classical sense was upended, why stop there? His disciple, French conductor and composer Pierre Boulez, took it further and applied the same principle of tone row pitch to all the elements of music—pitch, duration, tone production, intensity, and timbre. Another French disciple, Edgar Varese, asked why even 12-tone at all? Even he could not abandon all order, though. The American composer John Cage went the whole way and simply “created noise through chance operations.” Now you know why it sounds so ugly. That is its point.

This dreary story of the nihilistic revolution in music—as well as in culture generally—is somewhat well known, but Reilly lets us in on the little secret that this revolt in music has spent its course. How does he know? He interviewed the counterrevolutionaries, starting with the most important, University of Pennsylvania composer George Rochberg, who was a leading 12-toner when in 1964 his son died. Rochberg became frustrated that he could not express his deep emotions in the new orthodoxy and dramatically turned back to tonal passages. Reilly’s interview with him must be read in full, but let me note two things. Here is Rochberg on his feeling at the time:
