AACR2 does not define the ranges of vocal types. General practice is to follow the instructions given in the Subject Cataloging Manual: Subject Headings section H 1917.5: Base vocal range on the verbal indication on the item. If no vocal range is indicated, use the ranges specified in the New Harvard Dictionary of Music:
|High voice||Medium voice||Low voice|
|Soprano: C4-A5||Mezzo soprano: A3-F5||Alto: F3-D5|
|Tenor: B2-G4||Baritone: G2-E4||Bass: E2-C4|
note that these definitions, from
the New Harvard Dictionary of Music, are used in music cataloging,
using the Library of
Congress Subject Headings and
Anglo-American Cataloguing Rules, 2nd ed.
Vocal ranges for solo or choral works may differ, as evidenced from the different ranges found in other sources.
For example, see:
° The Wikipedia article on vocal range, which gives different ranges for operatic works and choral works.
° Catherine Schmidt-Jones' article and chart.
° Grove Music Online definitions:
|soprano:||C4 to A5|
|mezzo-soprano:||A3 to F#5|
|alto:||G3 to E5 (and contralto as F3-D5)|
|tenor:||roughly C3 to A4|
|baritone:||A2 to F4|
|bass:||F2 to E4|
