This is done when it is a question of introducing a rich tone into the upper octave which the trumpet is not capable of imparting. If a single horn is used, the upper part is allotted to 2 clarinets, 2 oboes, or 2 flutes. But if there are two horns playing the lower octave in unison, three or four wind instruments will be necessary above, especially in forte passages:
| 8 | [ | 2 Ob. or 2 Cl. or 2 Fl. 1 Horn | as well as | 2 Ob. + 1 Cl. 1 Horn | >[ | 8; | 2 Fl. + 2 Cl. 2 Horns | >[ | 8. |
To double a trumpet in the upper octave three or four wind instruments are required, but in the top register two flutes will suffice.

Wood-wind instruments should not be used to double a trombone in the octave above; trumpets are more suitable.
Examples of doubling in octaves:
* Snegourotchka 71—
| Ob. + Cl. Horn | >[ | 8. |
* Legend of Tsar Saltan, before 180—
