Instruments of the Orchestra, a program for elementary
and junior high school pupils presented by the
Wisconsin School of the Air.
Your teacher is Professor Richard C.
Church and Doctor of the University of
Wisconsin Symphony Orchestra.
Hello boys and girls.
I wonder how many of you know the
name of this instrument that I was playing on just now.
What is it?
The violin, that's right.
Now tell me what family of instruments it
belongs to.
The string family.
We've talked quite a bit about families of the instruments
of the Orchestra, haven't we, in the last few programs.
We've learned that there are four main families
of instruments in the Symphony Orchestra.
And we've learned that the conductor uses a musical
score that has in it all the parts to be played by
the various instruments.
Let's take a look at this big picture of an orchestra
conductor's score and another look at these four families.
At the top of the score we have the woodwinds.
And that includes the flutes and the obos, the
clarinets and the bassoon.
Then we have the brasses, the French horn, trumpets,
trombones and tuba.
And then the percussion family.
You remember that on our last program we talked about
the percussion instruments.
Now we're ready to talk about the strings.
The violins, violas, the alone
chalos and the bass violes.
On our first program we had a look at all of these string
instruments. Well that was quite a while ago wasn't it.
I think it would be a good idea if we had another quick look at
them. This one here is a viola.
Now as you can see it's larger than the violin and so it's
going to have a deeper sound.
This next one is a lot larger than a violin.
Its name is the violon chalos.
And because it's larger it'll
have a much lower sound.
The next one over here is the biggest of all of the
string instruments and its name is the bass viol.
And it will have the very lowest sound of all of the
string instruments.
Well now why do you suppose we
call this a string family?
Well it's because the vibrations which make us hear a sound
are produced by strings.
Let's take a close look at this violin back here.
Here you see the four strings.
They're fastened down at this end and then they cross over
this bridge and go up along this fingerboard and right
over this saddle up here.
These four pegs are for tuning the strings.
The more you tighten the strings
the higher the sound.
If you tighten it too much while the string breaks so
we're careful not to tighten them too much just right to
make the open strings and tune.
The violin is a very beautiful looking instrument.
Notice how graceful this scroll up here is.
And notice these two holes that have been cut very
carefully in the top of the instrument to make it sound
better. They're called the F holes because this one looks
like a very graceful letter F.
All of the string instruments are made of wood.
One kind of wood is used for the top of the
instrument and another kind of wood is used for the back of the
instrument to give the finest quality of the instrument.
The finest quality of tone possible.
The exact shape of the violin makes a great difference
in its tone quality also.
I think it's very interesting to realize that this shape
for the violin was developed a hundred years and more
before the revolutionary war.
And no one has been able to improve on it since that time.
Well let's hear what these open strings sound like, shall we?
[Bell]
I wonder how we could play the rest of the notes in that
tune. Well let's see.
We know that the vibration of the
strings produces the sound.
And when we play on an open string the string
vibrates from this bridge up here to this saddle.
Now if I place a finger firmly on the string that's
going to make the vibrating part of the string shorter.
You see my finger here is going to stop the vibration just the
same as the saddle does up here.
So the string will vibrate from the bridge up to
whatever finger I put down.
Now when I put down a finger and make the vibrating part
of the string shorter is that going to make the sound lower or
is it going to make it higher?
Well now let's think about that a minute.
When we were talking about the woodwind
instruments, do you remember?
We found that the piccolo and the flute had higher
sounds than the big bassoon.
And when we talked about the brasses we learned that
the trumpet had a higher sound than the big cuba.
So what do you think will happen when we make the vibrating
part of the string shorter?
Well it's going to make the sound higher, isn't it?
Let's see if it works that way.
[Bell]
You see as I shorten the string the sound got higher.
Now if I pick up those fingers then the sound will
be lower again, won't it?
[Bell]
Now I think we could finish that little tune I started to play.
[Bell]
If I put one finger down after the other and change from
one string to the next one at the right time I can do this.
[Bell]
So I've run out of fingers.
Do you suppose I can play any higher on the violin?
Yes I can if I shift the position
of my whole hand up here like this and I can start
over using the fingers again.
[Bell]
As you can hear the violin can play very high notes and we've
learned now that when the string vibrates at a shorter length
that makes the fit higher.
Well now that works the same way on all of the string
instruments but what makes these strings vibrates?
Well I wonder how many of you know what the name of
this thing that I have here is.
This is called a bowl.
Now I imagine one of you think of the word bowl you think
of the kind of bowl that you use to shoot an arrow with.
Don't you?
Well actually originally the bowls that were
used to play string instruments were just like a hundred bowls.
But this shape was developed all about about 50 years before
the civil war and this is now the modern shape of the bowl.
This stick is made of wood but if you didn't know what
this white stuff here is you might have a hard time
guessing because it's made of hair from the tails of horses.
It's a fasten up here at this end and then it has a
screw mechanism down here to tighten it when we want
to or to loosen the hair.
Now when you girls get all dressed up you sometimes
like to have your hair wavy or curly don't you?
Well this hair has to be combed out nice and straight.
Well I think it's about time we heard some music played
by a good violinist and we have a guest here today who
is going to play for you.
His name is Joseph Schullhard.
Now well while Joe is playing you watch how he
puts his fingers down to shorten the string length
and change the sound and watch how he uses the bowl
to make the strings vibrate.
He's going to play some gypsy music called "Charles."
[Music]
Thank you very much.
Joe went to high school in Springfield,
Missouri and now he's a member of the University of Wisconsin
Symphony Orchestra.
His accompanist is Janis Wickey.
In addition to being a piano player she's an excellent
cello player and she also plays in the orchestra.
Did you notice that while Joe was playing his hand was
waving back and forth like that part of the time?
Now why do you think he did that?
Well that's to make the sound much more beautiful than it
would be if he didn't do it.
There's a special name for that that I'd like to have you
learn today.
It's called "The Brottle."
Now all good singers have a natural vibrato which
makes their voices sound warmer and more appealing than they
would be if they didn't have it.
And so when a violinist plays a melody he uses a vibrato to
make it sound more like singing.
The other instruments in the Symphony Orchestra use
a vibrato sometimes too when they want to make
their music more song-like.
There's another effect that's used on the string instrument
sometimes that I'm going to tell you about for just a
moment. Sometimes you pluck the string with your finger
instead of using the bowl.
And the name for that is "Pizzicato."
Sounds like this.
[music]
"Pizzicato." Well now whether you play "Pizzicato" or whether
you play with the bowl the violin is one of the very
finest instruments that you could possibly learn to play.
If you practice faithfully and get to be good you'll have
plenty of chances to play in a Symphony Orchestra because
it takes lots of violin to make a Symphony Orchestra
sound the way it should.
Next time we're going to talk more about the instruments
of the string family, the viola and the violon cello.
See you then.
Goodbye.
