U2 released One in 1991 on Achtung Baby. The track remains a staple for singers who want to test range and control at moderate tempos. The measured vocal line spans G3 to C5 across 17 semitones. Phrasing tempo sits near 62 BPM with a note density of 0.4 notes per second, producing a medium difficulty rating.
What makes it medium difficulty is the sustained phrasing combined with the 17-semitone span. Singers must move from low chest voice at G3 into a clear mix by the time they reach C5 without pushing. The 62 BPM tempo gives time to shape each phrase, yet the length of individual lines still demands steady breath support. The 0.4 notes per second density means the melody does not race, so the main challenge is dynamic control rather than speed.
Tenors and high baritones fit the measured range best. Lower baritones can transpose down a third and still keep the emotional weight. Sopranos and altos often find the upper C5 comfortable but may need to adjust the lower G3 passages into a lighter head voice to avoid muddiness.
Practice starts with isolated phrases that cross the passaggio around A4 to B4. Sing each phrase on an open vowel first, then add consonants only after the pitch and volume stay consistent. Because the tempo is moderate, record yourself at 62 BPM and check that the tone does not thin on the way up or flatten on the way down. Once single phrases feel secure, chain two or three together while keeping the same breath pacing. The full track runs 267 seconds, so build stamina by repeating the verse-chorus block without dropping support.
When the measured range and tempo feel manageable, upload the song to PitchHighway and learn it phrase by phrase.
