From the video

Answers: Why does the backing vocal in Adele's Rolling in the Deep sound off to some listeners?

• music theory
• backing vocals analysis
• tonal harmony
• perceptual bias in music
• minor key chord progressions

What it concludes

• The backing vocals in Rolling in the Deep use an A natural note in the pre-chorus, which contradicts the diatonic A flat expected in the key of C minor.
• Repetition and prior musical expectations cause listeners to mishear the A natural as A flat.
• Gospel-style vibrato and pitch oscillation obscure the exact pitch of the note, leading listeners to fill in what they expect to hear.
• The 5-b6-5 melodic movement is a common trope in European music associated with grief and minor keys.
