, thirds or sixths invariably leads to
satisfactory results. For the same reason the employment of brass
instruments of different kinds, arranged according to normal order of
register:

Trumpet Trumpet Trombone 2 Trombones 2 Trumpets 2 Horns
2 Horns Trombone Tuba Trombone + Tuba 2 Trombones Tuba

is likewise successful whether the instruments are doubled or not.
Another possible method, though not so reliable, is to combine horns
(above) with trombones, exclusively in octaves:

2 Horns ] 4 Horns ]
1 Trombone] 8 or 2 Trombones] 8.

_Examples:_

_Sadko_, before [[120]]--Trumpet/Trumpet] 8.

_Sadko_ [[5]]--2 Trumpets/4 Horns] 8.

_Snegourotchka_ [[222]]--2 Trombones/Trombone + Tuba] 8.

_Ivan the Terrible_, Act III [[10]] 1 Trombone + Trumpet/2 Trombones]
8 (cf. Ex. 38)

_The Golden Cockerel_ [[125]]--Trumpet/Trombone] 8.

Cf. also _Snegourotchka_ [[325-326]]--Trombone/Trombone] 8 (Ex. 95).

Melody in different groups of instruments combined together.

A. Combination of wind and brass in unison.

The combination of a wood-wind and brass instrument produces a complex
resonance in which the tone of the brass predominates. This resonance
is naturally more powerful than that of each instrument taken
separately, but slightly sweeter than the brass instrument alone. The
tone of the wood-wind blends with that of the brass, softens and
rarefies it, as in the process of combining two wood-wind instruments
of different colour. Instances of such doubling are fairly numerous,
especially in _forte_ passages. The trumpet is the instrument most
frequently doubled: Trumpet + Cl., Trumpet + Ob., Trumpet + Fl., as
well as Trumpet + Cl. + Ob. + Fl.; the horn, less often: Horn + Cl.,
Horn + Fag. Trombones and Tuba may also be doubled: Trombone + Fag.,
Tuba + Fag. Combining the Eng. horn, bass clarinet and double bassoon
with the brass, in corresponding registers, presents the same
characteristics.

_Examples:_

_Legend of Kitesh_ [[56]]--Trombone + Eng. horn.

* _Mlada_, Act III, before [[34]]--3 Trombones + Bass cl.

As a rule, the addition of a wind to a brass instrument yields a finer
legato effect than when the latter instrument plays alone.

B. Combination of wind and brass in octaves.

Doubling the horns in octaves by clarinets, oboes or flutes often
replaces the combination

1 Trumpet ]
1 Horn (or 2 Horns) ] 8.

This is done when it is a question of introducing a
