The voice
Billie Eilish is a light mezzo-soprano (some references call her a soprano) whose range is commonly cited at roughly D3–B5. The recognisable thing is not the range but the proximity: she sings a few centimetres from the microphone at a near-whisper, so every breath, click and sigh becomes part of the record. Under that hush sits a genuinely accurate, flexible voice, with clean head-voice leaps in Ocean Eyes and a real belt held in reserve for the second half of Happier Than Ever.
Her songs look easy on paper, mostly E3–E5, and that is the trap. Singing quietly in tune, with no vibrato to hide behind, is harder than belting. Work on steady, slow airflow, a relaxed jaw and pitch that lands dead centre; a tuner or the app will show you every drift. Do not try to reproduce the studio breathiness by pushing air, it will just tire you out; think of a light, speech-level tone very close to the mic instead. Save real volume for the songs that actually ask for it.
Range moments worth studying
Ocean Eyes
Verses sit low around E3–B3, then the chorus floats up to around E5 in a pure, airy head voice.
Bad Guy
Almost spoken, hovering around F#3–A3 with quick rhythmic bursts; pitch accuracy at low volume is the whole challenge.
Happier Than Ever
Half whispered ballad, half rock catharsis; the closing section pushes to sustained belts around C5–D5 with real grit.
Everything I Wanted
A gentle E3–C#5 lullaby where the melody barely rises; breath control and tone matter more than notes.

Whether a song feels good depends on where its melody sits.
