Lyrical climaxes, a piena voce, or dramatic passages for the voice situated outside its normal range should be supported melodically and harmonically by the orchestra, in the register in which the voice is placed. The culminating point in such passages often coincides with the entry or sudden attack of the trombones or other brass instruments, or by a rush of strings. Strengthening the accompaniment in this manner will soften the tone of the voice.
Examples:
[No. 280.] The Tsar's Bride 206.
Servilia 126-127.
" 232.
[No. 281.] Sadko 314.
If the culminating point is soft in colour and outline it is better left unsupported in the orchestra, but sometimes the wood-wind, sustaining such passages with light transparent melody or harmony may produce an entrancing effect.
Examples:
Snegourotchka 188.
