Singing Sucker: what your voice is in for
Sucker is engineered pop adrenaline, and the vocal design is smarter than it sounds on the radio: the researched B3 to C#5 range spans only 14 semitones, but the Jonas Brothers push most of it into the top half, where Nick's verses strut in falsetto and Joe's chorus lands in bright full voice. The stored key is C# minor at 86 percent confidence.
The deciding moment is the falsetto verse: it must bounce, in tune and rhythmically cocky, which is harder than a sustained high note because falsetto agility exposes any looseness in the mechanism. The technique is percussive falsetto, treating each note as a plucked string with a clean start and stop. The chorus then demands the opposite, a connected full-voice ring at C#5 territory. Altos and mezzos fit the stored range outright; the page's key math seats altos two semitones down in B minor and mezzos one semitone up in D minor. Sopranos are one semitone shy of the floor, trivial. Tenors face four semitones of full-voice ceiling and should take the six semitone drop to G minor, or simply mirror the recording and split registers.
Practice cue: sing the verse hook staccato in falsetto, one clean onset per note, no slides. Bounce is built one clean attack at a time.
