Glockenspiel, Bells, Xylophone.
The glockenspiel (campanelli) may be made of steel bars, or
played with a keyboard. The first type is the more satisfactory
and possesses greater resonance. The use of the glockenspiel is
similar to the celesta, but its tone is more brilliant and penetrating.
Big bells in the shape of hollow discs or metal tubes [6],
or real church bells of moderate size may be considered more as
theatrical properties than orchestral instruments.
The xylophone is a species of harmonica composed of strips or
cylinders of wood, struck with two little hammers. It produces a
clattering sound, both powerful and piercing.
To complete this catalogue of sounds mention should be made
of the strings playing col legno, that is with the wood or back of
the bow. The sound produced is similar to the xylophone, and
gains in quality as the number of players is increased.
A table is appended showing the range of the celesta, glockenspiel
and xylophone.
