Singing Sleep Like a Baby Tonight: what your voice is in for
Sleep Like a Baby Tonight is U2 in art-rock mode: a hushed, unsettling lullaby where Bono abandons his stadium chest voice for long stretches of veiled falsetto. The researched E3 to C#5 range spans 21 semitones, but the number hides the real story: the top third of the song lives in sustained head voice, which is why the difficulty score reads 78 on a track with no belted climax.
The deciding moment is the falsetto verse, where the melody hovers around the upper register at low volume over a skeletal arrangement: every waver is audible, every pitch drift exposed. The technique is falsetto sustain with core, keeping a thread of focus in the head voice so it reads as eerie rather than weak. This is advanced registration control dressed as a quiet song. Tenors face four semitones of stored ceiling in full voice but fit comfortably once the top is taken in falsetto as intended. Altos are one semitone shy of the floor and otherwise clear. Baritones face eight semitones of ceiling; with no stored key, four or five semitones down keeps the falsetto passages from becoming a squeak.
Practice cue: sustain a soft head-voice note and slowly add a sliver of edge without letting volume rise. That sliver is this whole song's sound.
