I'm Not The Only One

The harmony of "I'm Not the Only One" is deliberately minimal — a single four-chord loop (I-vi7-IV-V) sustained across the entire song. This gospel-influenced approach places all emotional weight on Sam Smith's vocal performance and the orchestral arrangement rather than on harmonic variety. The vi7 chord provides just enough minor-key color to underscore the song's themes of heartbreak within an otherwise warm, major-key framework. The simplicity makes it highly accessible for beginner musicians while demonstrating how restraint in harmony can serve powerful songwriting.

Sam Smith wrote "I'm Not the Only One" with collaborator Jimmy Napes. The song emerged from a deeply personal place, dealing with themes of infidelity and heartbreak. Smith chose it as a single because they wanted to release something classic with longevity, rather than a safer radio bet, stating they wanted to make a statement and have people buy into the album.

Released as a single from Sam Smith's debut album In the Lonely Hour (2014), "I'm Not the Only One" blends piano-driven soul with gospel structure and sweeping strings. The song became a worldwide hit, reaching the top five in both the US and UK, and earning multi-platinum certifications across more than ten countries.
