Naïve and Sentimental Music: Naïve and Sentimental Music is a symphonic work by the American composer John Adams.  The title of the work alludes to an essay by Friedrich Schiller, "On Naïve and Sentimental Poetry", that contrasts a creative personality that creates art for its own sake (the "naïve") versus one conscious of other purposes, such as art’s place in history (the "sentimental").  The composer cites both the slowly developing harmonies of Bruckner's Fourth Symphony and the atmosphere of the Sonoma coastline (where the piece was composed) as inspirations for the work.  The piece was co-commissioned by the Los Angeles Philharmonic, the Ensemble Modern, the Vancouver Symphony Orchestra, and the Sydney Symphony Orchestra.  It received its first public performance by the Los Angeles Philharmonic conducted by Esa-Pekka Salonen on February 19, 1999.  A recording by Salonen and the Los Angeles Philharmonic was subsequently released by Nonesuch Records.
