Bernstein's premiere and subsequent interpretations were later widely criticized for taking liberties with the score. The score used in 1951 contained about a thousand errors, but in addition Bernstein made a substantial cut to the finale, ignored some of Ives's tempo indications, changed instrumentation, and prolonged the terminating "Bronx cheer" discord from an eighth note to more than a half note. Many conductors and audiences, influenced by Bernstein's example, have considered the last of these practices one of the trademarks of the piece. In 2000, the Charles Ives Society prepared an official critical edition of the score and authorized a recording by Kenneth Schermerhorn and the Nashville Symphony Orchestra to adhere more closely to Ives's intentions.
