J. M. W. Turner's "The Fighting Temeraire" is a perfect example of the nostalgia part of the Romantic theme. The painting shows an old ship being towed in by a tug boat. This portrays the traditional times that the Romantic artists feel nostalgic about being replaced by the modernity which is symbolized by the dark tug boat.
Tchaikovsky's 1812 Overture: Many of the themes that made pre-romantic music was the calming tone of soft instruments. For example the song that played at the ball in the clip of Harry Potter seemed like music that suited more the dancing, ballroom style. Many of the styles of the pre- romantic era are still present in Tchaikovsky’s 1812 Overture, for example, the first seven minutes are very telling of themes past. However once the song reaches eight minutes it starts to transition into a romanticized song. The themes that the song has that makes it Romantic is the booming of the drums and very ominous sounds made by percussion instruments.
