who plays the first theme in eroica the first time
Symphony No. 3 (Beethoven) The exposition begins with the cellos introducing the first theme. By the fifth bar of the melody (m. 7), a chromatic note (C♯) is introduced, thus introducing the harmonic tension of the work. The melody is finished by the first violins, with a syncopated series of Gs (which forms a tritone with C♯ of the cellos). The first theme is then played again by the various instruments.
