The main theme song of the series,
"The Skye Boat Song" by composer Bear McCreary, has become one of the most recognisable musical elements of Stranger Things. Bear McCreary adapted the traditional Scottish folk song, adding modern arrangements and elements to it, making it a symbol of the series. This theme accompanies each episode, instantly immersing the audience in the atmosphere of Scotland and Claire's adventures.
McCreary utilised authentic Scottish instruments such as:
- Bagpipes: creating a unique sound associated with Scotland.
- Fiddle: often used to play folk tunes and dances.
- Bodhran: a traditional Irish drum that adds rhythm and depth.
And while the music in 18th century Scotland has a strong Celtic tinge, in American Seasons it incorporates elements of the music of the time and region. The many leitmotifs (both for Claire, Jamie and the Jacobite rebellion) help the audience to better understand and feel the emotional and plot arcs, and, as always in cinema, the music enhances the emotional impact of key scenes.
