About Viols
Instruments of the Viola da Gamba family, often
called
viols, are made in very many shapes and sizes.
The most common sizes of viols are the treble, which is about
the size of a violin, the bass, which is about the size of
a cello, and the tenor which is between the two. There are
also larger and smaller viols. Some have a shape which resembles
a violin, others have plainer corners or a much fancier outline.
They are always held on the knees or between the legs and
are usually played with a bow (which is held underhand). Most
viols have C-shaped soundholes and a flat back. Strings are
usually made of gut, like the frets which are tied around
the neck and are partly responsible for viols' sound quality.
The rich, clear sound of viols means they blend well with
each other and with other instruments or voices. Most viols
have six strings, but some have more and others fewer. Many
tunings have been used but by far the most common has the
following intervals between adjacent strings: 4th - 4th -
3rd - 4th - 4th, with the top string tuned to d, a or g.
