Example:
Snegourotchka 291-300 (cf. extract, [Ex. 118]) Sopr. and Bar.
The use of similar voices in pairs:
| Sopr., | Ten. |
| Sopr., | Ten. |
entails singing in unison and thirds. They should rarely be separated beyond a sixth, but crossing of parts is inevitable, as otherwise the resultant volume of tone would be too weak.
Note. Other possible combinations:
| C.-alto, Bar., | M.-sopr., Ten., |
call for no special remarks.
Examples:
* The May Night, Act I pp. 59-64—Mezzo-sopr. and Tenor.
