B2D#4

G to E · 3 semitones down

The source sheet marks this range for review.

Provisional: a published melody lead sheet lists G3–B4 in C; transposed to the recorded key G, that gives D3–F#4. Verify against the recording.

Reference

Standard vocal types

Typical full ranges for the six common voice classifications:

Voice type	Typical range
Soprano	C4–A5
Mezzo-soprano	A3–F5
Alto / contralto	F3–D5
Tenor	B2–G4
Baritone	G2–E4
Bass	E2–C4

These are approximate reference ranges, not strict limits. Voice type also depends on where singing feels comfortable (tessitura) and on vocal tone; many contemporary singers don’t fit neatly into one category. Ranges adapted from the Yale University Library vocal-range reference.
