Can you sing Don’t Look Back by Boston?

Don't Look Back is arena-rock precision engineering: Boston's Brad Delp sails through layered harmonies and a lead line that lives high and stays there, with the researched F#3 to C#5 range concentrated brutally in its top third. The 84 difficulty score is honest: this is sustained high-tenor work with no place to rest.

The deciding moment is the chorus stack, where the lead sustains around the C#5 ceiling while harmonies swarm underneath: the singer needs not just the notes but the ring, Delp's laser-focused, bright production that cuts through guitars without distorting. The technique is high mix endurance, keeping the larynx stable and vowels narrow through phrase after phrase near the top of the range, because the song never comes down long enough to recover. Altos fit the stored range outright, and honestly inherit it more easily than most men. Tenors face four semitones of ceiling; with no stored key, three or four semitones down brings the choruses into sustainable territory. Mezzos are three semitones shy of the floor, trivial. Baritones should think five or six semitones down and still expect a workout.

Practice cue: sing the chorus once, rest thirty seconds, and repeat five times. The fifth take is the real audition; arena rock is a stamina sport.
