Violin
The violin has been largely unaltered for centuries and is the most recognized
of the orchestra instruments. It is the soprano or the highest voice in the
string family. Beautifully toned and high pitched, the violin is often used
as a lead or solo instrument.
Viola
The viola is slightly larger and tuned
differently than the violin. It is also played under the chin. The viola produces
sombre, moody tones and is the alto voice of the string family. It adds depth
and richness to the orchestra
Cello
The cello is the tenor voice of the orchestra. It is tuned a full octave lower
than the viola. Unlike the violin or the viola, the cello is supported on
the floor by an endpin while the seated musician steadies the instrument with
his or her knees. The cello produces deep lower registers and subdued higher
tones.
Bass
The bass is the string family's largest instrument. It may be played with
a bow or plucked by hand in either sitting or standing positions. The bass
is the deepest voice of the string family. The deep sound of the bass gives
foundation to the orchestra.
