TV show theme songs can remain in our memories for decades, says Kirsten Zemke – an ethnomusicologist at the University of Auckland’s School of Social Sciences. Zemke shares with RNZ how some viewers even use theme songs to form a first impression and decide whether or not to watch a show. Instrumental openings and lyrical ones are both popular, and it’s also a way for composers to get their songs out into popular culture. The Game of Thrones opening song is an example of an orchestral theme that has become iconic, Zemke says.
