Tearin’ Up My Heart

The Cheiron Studios philosophy was to subordinate harmonic motion to the hook and the groove, and 'Tearin' Up My Heart' is a textbook example. Working in A minor at 110 BPM, Martin and Lundin keep the progression short and looped, letting the layered vocal harmonies and the funk-styled pre-verse carry the textural interest. The absence of any dominant seventh or chromatic movement means the song never resolves in the classical sense — a harmonic choice that mirrors the lyric's portrait of a relationship suspended in uncertainty.

After NSYNC's debut single 'I Want You Back' started charting in Europe, their German label BMG Ariola pressed for a follow-up with similar energy but broader American appeal. Max Martin and Kristian Lundin wrote 'Tearin' Up My Heart' in three days at Cheiron Studios in Stockholm. The song had originally been pitched to the Backstreet Boys before being handed to NSYNC. JC Chasez later said the track would help bookend their concerts alongside 'two hit songs.'

Written in three days by Max Martin and Kristian Lundin after 'I Want You Back' broke in Europe, 'Tearin' Up My Heart' distilled the Cheiron formula — funk-edged groove, driving beat, stacked vocal harmonies — into a track that went top 10 in Germany and the UK. Its 1998 American release and three MTV VMA nominations gave it lasting cultural traction. The song remains one of the defining artifacts of the late-90s boy band era.
