The orchestral
string instrument family is made up of violin, viola, cello and double
bass. In this article we will discuss the components and manufacturing
of strings and give our recommendations in order to assist schools,
parents and players to choose the most appropriate instrument for
their needs.
The
Components of a Violin
We will start by looking at the violin, how it is made and its various
component parts, all of which are important to the quality of the
finished instrument. Whilst concentrating on the violin these comments
are equally pertinent for the other instruments of the string family.

Manufacture
Violins have been manufactured throughout Europe in considerable
numbers for at least 200 years, in which time the central process
of carving fronts and backs from solid tonewoods has hardly altered.
Since the 1950s, large-scale production has also developed in
Asia with now the vast majority of student instruments coming
from China. Some very cheap student models feature pressed fronts
and backs however, the end product is not of a high standard
and can not be recommended. Better quality instruments have fronts
and backs that are hand carved from solid tonewoods. |
Materials
Fronts are made from spruce and should be dried to a moisture content
of 8% or less. This is achieved by air-drying over a long period
or by a combination of air and kiln drying. Fronts are made from
two pieces split from the same piece of wood. The front can be
referred to in a number of ways; table, belly, soundboard, the
last description being particularly apt as the sound is amplified
by the front.
Back, ribs and neck are made from wood from the acer family, usually
maple or sycamore. Linings are made from willow, being relatively
hard, but flexible; spruce or pine is used for the bass bar, soundpost
and blocks.
The various components are glued together using traditional animal
or fish glues as opposed to resin based or permanent glues (for ease
of repair purposes). The wood is then varnished, usually on student
instruments with a nitro-cellulose varnish. |
 |
Bridge
The bridge is an important part of the violin in terms of sound and
playability and its correct fitting is vital. The more expensive
the bridge, the higher quality of the wood (maple) used. |
Pegs
and End Pins
Pegs are generally made of ebony, rosewood or boxwood although some
cheaper instruments use stained hardwood (usually pearwood). Correct
fitting is important as tight pegs may cause damage to the instrument
and loose pegs may slip and cause tuning problems.
|
 |
 |
Tailpieces
Tailpieces are traditionally of the same wood as the pegs however
over recent years the use of alloy and composition tailpieces
with integral adjusters for use with metal and pearlon cored
strings has greatly increased. |
Tailguts
Traditional gut is now rarely used and the nylon adjustable tailguts
are almost universal.
Adjusters
Integral adjusters are now the norm on student instruments although a
single adjuster on the E is more appropriate for instruments fitted
with pure gut strings.
Chinrests
Chinrests are traditionally ebony, rosewood, boxwood or stained hardwood
although plastic chinrests are generally accepted by teachers
for student instruments.
|
 |
Fingerboards
As a fingerboard will wear with use, the best material is ebony which
can be re-shaped or scraped smooth. Stained rosewood is perfectly
acceptable for student use; stained whitewood is only used for the
very cheapest instruments.
Bass Bar
The bass bar is made from pine or spruce and is glued to the front adding
support and tension. Any part of the bar that is unglued will cause vibration.
The bass bar is an integral part of the soundboard for the transmission
and quality of the lower notes.
Soundpost
The soundpost combines with the bass bar and bridge to create the "nervous
system" of the instrument, these pieces playing a vital part in
the quality of the final tone and sound. A well-fitted soundpost will
release the full potential of the instrument; one poorly fitted will
do the exact opposite. Located just behind (tailpiece side) the treble
foot of the bridge, it conveys the treble vibrations directly to the
back of the instrument, whilst acting as a fulcrum to allow the bass
bar to vibrate fully.
Purfling
Purfling (originally whalebone) is made from dyed wood, such as poplar
and pear, or fibre. It is inserted into a channel cut into the front
and back, usually after the body of the instrument has been assembled.
Its presence is more than just decorative, as it also acts as a guard
against cracks spreading from the edge of the instrument. Some low quality
violins have painted purfling which performs no useful purpose.
F Holes
F Holes are cut with a fret saw and then carefully finished with a knife.
In addition to allowing the sound from the instrument, their size and
shape give flexibility to the front.
 |
Bows
The bow acts as an extension to the arm, and should be able to transfer
any minute nuances that the player intends. Because of this,
the weight, (around 60g for a 4/4 violin bow) balance, spring
and "feel" of a bow must be right. |
| The
best bows are made from a dense, slow growing wood known as
Pernambuco. Its dense fibres are ideal for the fine shaping
necessary to form a bow, and the wood takes to being "sprung" extremely
well. It is characteristically a deep red-brown colour, with
a perceivable grain. It can be distinguished from its cheaper,
faster growing cousin, Brazilwood, which has a grayer appearance,
and a wider grain and is used for student bows. Other materials
are also used for the bow stick; there are some good student
fibreglass bows fitted with natural hair (such as the P&H
brand), and carbon fibre is increasingly being used for better
quality bows. |
Strings
Steel mono core strings (such as Dogal Green and Astrea) are the
norm for student instruments. Steel flexible core strings (such
as Helicore) are very flexible and particularly popular for cello
and bass. Synthetic gut (Dominant, Tonica etc) are favored by
many student and professional players whilst genuine gut core
strings (usually Pirastro Olive or Eudoxa) are found on the finest
instruments. With genuine gut core strings an adjuster can only
be used on the violin E string, (which is usually metal).

Set
Up
Before every stringed instrument is dispatched from Normans it is set
up to a high standard and rigorously tested to ensure the instrument
is set to play to its full potential when you receive it. Component parts
of this procedure include:
Soundpost
set up
Bridge and nut profiled
Pegs tested for correct fitting
Feet of bridge adjusted for optimum contact with front
String height set to Stentor standard recommendations
Strings and adjusters checked
Bow tested for tension and straightness
All key components tested
Please note,
all instruments are delivered with their bridge down to reduce
the risk of damage in transit. This can easily be re-erected by
your teacher.
What size violin for a child?
The importance of a child using the correct size of instrument cannot
be over stressed. To size up the child, the instrument should firstly
be held by the student in the playing position. An instrument of the
correct size will allow the player to extend their left arm and comfortably
cover the scroll with their hand, without stressing the elbow. The gap
between the arm and violin back should be wide enough for a fist
In calculating the size of an instrument, a measurement is taken along
the back excluding the heel button. The table below gives APPROXIMATE
average sizes of violins & bows. There are variances from these:

Recommendations
Student Violins
There are a large number of competing brands available within the UK
market place most of which (such as Primavera and Antoni) come from Chinese
trading companies and offer adequate performance. However, we generally
recommend Stentor products.
Stentor, (a British company, established in 1895) are world market leaders
in the manufacture of student stringed instruments and are the only independent
company with a wholly owned violin factory in China. Consequently the
instruments are typically of a good tone and consistent quality.
Stentor I v Stentor II
Stentor student instruments fall into two categories, namely the I and
II series. Stentor II instruments offer enhanced specifications and build
quality over and above the standard Stentor I models.
Both ranges
feature solid carved table and back, inlaid purfling, metal tailpiece
with integral adjusters, quality lightweight case and are available
in all sizes from 1/16 to full sizes (4/4). The Stentor I features
rosewood pegs and blackened fingerboard whereas the Stentor II
has ebony pegs, nut, saddle and fingerboard.
| For
the most flamboyant of young players! there is a range of coloured
Harlequin violin outfits. These are based on the specifications
of the Stentor I instrument. |
|
 |
We
generally recommend the Stentor I for very young players (who
might quickly outgrow their instrument) whereas more advanced
players using 3/4 or 4/4 violins generally opt for the higher
specification Stentor II. |
Intermediate
Violins
The Stentor Conservatoire is designed for the intermediate student
and offers a high standard at a reasonable cost.
The
violin is hand carved from attractive tonewoods and comes
complete with a professional style oblong case. Whilst
available in a number of sizes we typically sell full size
outfits to more experienced students. |
 |
 |
Advanced
Student Outfits
For advanced students we generally recommend the Stentor Messina
which are superb handcrafted instruments carved from selected and
figured tonewoods. These instruments are made in specialist workshops
within the Stentor factory, where the most skilled individual workers
work under the close supervision of a master maker. This process
produces fine instruments with their own unique characteristics.
The outfit comes complete with oblong case and pernambuco bow. |
Violas
Our recommendations on violas mirror those of the violin with Stentor
making equivalent violas for all the models previously listed.
Violas are described by the length of their backs and not by fractional
sizes. There is no absolute standard but currently instruments used
by adults are mostly 15” to 16”. Stentor student models
come in a variety of sizes from 12” to 16”. Sometimes
younger students are taught viola on violins strung with viola strings.
This is not recommended, as the true viola sound cannot be achieved.
|
|
 |
Cellos
Again, student instrument recommendations mirror our violin selections,
however, generally all but the very young player tend to opt
for the Stentor II model due to its enhanced quality of workmanship,
ebony pegs and fingerboard and better quality padded cover. As
with the violins both models feature solid carved table and back,
inlaid purfling and metal tailpiece with integral adjusters. |
Double
Basses
Stentor offer a student double bass featuring a laminated back and
sides for customers on a low budget. However, most players prefer
to opt for the Stentor Conservatoire model (available in 3/4, 1/2,
and 1/4 sizes) which features a fully carved back and front, ebony
fingerboard, quality machine heads, flexible core strings, good student
quality wood bow and padded cover.
Double Bass sizes are particularly confusing to the uninitiated as
the 3/4 size is considered to be the “norm” for a full
size instrument. In rare instances when we have supplied 4/4 instruments
(contrary to our advice) as customers have insisted this is what
they want, they have asked later to return the bass as they have
found the size to be inappropriate. Common sizes are 3/4, 1/2 and
1/4.
An additional choice is the Andreas Zeller which are made in Romania
to Stentor specifications and offer outstanding value.
For the younger student the “Yorke mini bass kit” has
been designed to enable children as young as six to learn to play.
The kit includes a Zeller bass (1/4 or 1/8 size), padded cover, lightweight
bow, wooden stool, endpin location board, carrying strap and rosin. |

Silent
Strings
For players who need to practice in confined areas (such as music students,
or for long suffering parents!) the silent string range from Yamaha is
a great innovation. The player simply connects headphones into the silent
instrument, which is practically inaudible to anyone other than the musician
when played. |
