an e7, from a cover she recorded before any of this, and a register fewer than one trained singer in twenty can reach at all.
the short answer
the highest note commonly cited for her is an E7, in the whistle register, from an early cover of mariah carey's emotions. her working range is usually given as roughly D3 to E7 — about four octaves. the whistle register begins above about E6 and is accessible to a very small minority of trained singers.
what a whistle register actually is
the highest of the vocal registers, produced by a small portion of the vocal folds vibrating while the rest are held closed. it is physically a different mechanism from head voice rather than a continuation of it, which is why singers do not gradually reach it by practising high notes.
the sound is thin, piercing and almost pitch-pure, with none of the warmth of a belted note. that is a limitation as much as a feat: you cannot sing a lyric up there in any intelligible way, which is why whistle notes are used as an event rather than as a line.
where the number comes from
which songs actually use it
- my hair, from positions. the clearest studio example, and the one moment on an album that otherwise refuses to show off.
- imagine, from thank u, next. it closes on the register, and it is the most-cited whistle moment in the catalogue.
- no tears left to cry. used briefly and buried in the mix, which is characteristic — she hides them more often than she features them.
- live, more than on record. the register appears more on stage than in the studio, which is the opposite of what most people assume.
why it is not the interesting part
because it is a party trick and she treats it as one. the thing that actually distinguishes her instrument is at the other end: the ability to hold a quiet line at low volume with no support from the arrangement, which is what positions, eternal sunshine and petal are all built on.
the full piece on her voice makes that argument at length, and the vocal map draws the range rather than describing it.
