The voice

Sia Furler is a mezzo-soprano whose range is commonly cited at roughly C3–C6, about three octaves, though references vary. Her voice is one of the most distinctive in pop: a cracked, almost sobbing belt that pushes each vowel to its breaking point, a chewed, idiosyncratic diction that turns lyrics into instruments, and an ability to leap from a low murmur to a screaming top note in a single bar. It is the sound of Chandelier, Titanium and dozens of hits she wrote for other artists.

The trap with Sia songs is the strain. Those chorus notes around C5–D#5 sound like they are ripped out of her, but the effect is a stylistic crack laid over a supported, well-placed belt. Learn Chandelier with a clean, bright mix first, then add the breaks and swoops sparingly. Keep the jaw loose on her stretched vowels, plan breaths before each long line, and if the chorus starts to feel like shouting, drop the key. Stop and rest if your throat feels sore; the rasp is not worth an injury.

Range moments worth studying

Chandelier

The ‘one, two, three, drink’ verse sits low, then the chorus explodes into sustained belts around C5–D#5, repeated to exhaustion.

Titanium

Verses around G3–B3 and a chorus that climbs to D#5 with a long, held ‘titanium’; a favourite belt test.

Cheap Thrills

Her most forgiving hit, a bouncy F#3–C#5 with no big sustained notes.

Elastic Heart

Starts unusually low around C3 in the library’s chart, then leaps up more than two octaves for a raw, cracking chorus.

Can you sing it?

Mezzos and altos with a developing belt should start with Cheap Thrills (F#3–C#5); Chandelier and Titanium are for when your D#5 is reliable. A range label only tells you the edges. Whether a song feels good depends on where its melody sits. The Singing Coach AI app listens to you sing real songs, maps your range and tessitura, and tells you which keys and songs actually fit your voice, including whether Sia’s catalogue is in reach today.

Why does Sia’s voice crack when she sings?
