Unchained Melody — The Righteous Brothers
“Unchained Melody” by The Righteous Brothers is in Bb major, and the commonly cited lead-vocal range is C4–A5 — 21 semitones — which rates hard for an untrained voice.
The climb from C4 to A5 makes the ending the obvious headline, but the first job is controlled breath and an even legato line through the quieter opening. Practice the upper section softly and separately; the page's range fit is a boundary check, not permission to push for the recording's full volume or color.
Figures are the commonly cited range and published key for the studio version (Musicnotes original-key Singer Pro arrangement MN0133818, C4–A5 in Bb major), not lab measurements. No lyrics or melody are reproduced here — this page is about what the song demands of a voice.
