Viola's and some thoughts - For
as long as viola's have been played by children, the
problem of getting a good sound, especially on the
"C" string, has followed. Many things have
been tried from making an asymmetrically shaped instrument
to enlarge the air volume to a large body with a short
neck. None of things things have worked consistently and
even if they did, the cost is prohibitive to a new young
player. A very interesting test was tried a few years
back. The shop of Frederick Phelps in London conducted a
blind sound test of 13 small viola's before a panel of 60
private viola teachers. 7 instruments were in the 14"
size (4/4 violin equivalent) and 6 comparable to a
1/2 size violin. All the viola's had strings designed for
small viola's. The different models included hand
made viola's, commercially made viola's and violins strung
as viola's as well as a special experiment.
The clear favorites were
not the traditionally higher ribbed instruments but rather
the restrung violins and the clear runaway champion - the
experiment. A modification was made to a commercially made
violin in which a hole was drilled in the top of the
violin through which an extended sound post was fitted so
that the treble bridge foot sat directly on the post.
Although not recommended for a hand made higher grade
instrument, the modification produced stronger low
harmonics and resonances and reduced higher ones.
Some more experimentation
must be done, but the idea that the top of the instrument
being bypassed essentially to produce a more viola sound
on a small violin is intriguing
More information can be
found in Strings magazine articles December 2000 and June
2001.
Proper Bridge
Placement is achieved by following the
instructions that follow. The "f" hole notches
are only a guide and do not provide an exact placement
guide. The proper location is called the MENSUR which is a
ratio of neck length to bridge location. First measure the
distance from the nut to the edge of the violin next to
the neck. Take this number and divide by two and then
multiply by three, this resulting measurement (from the
edge by the neck, to the bridge) is the proper location of
the top of the front of the bridge (side closest to the
fingerboard) for violin. Thus a 2:3 ratio. For the Cello
the ratio is 7:10 and the Bass is 3:4.
