Construction
Rhydian Shaxson discusses the cello.
First, the instrument
itself: 
Next, the strings and the character of the instrument: 
Finally, the cello section of the orchestra:
It is important
to bear in mind that the notion of cantabile is inherent to the
cello: 
Cantabile works well in the low register as well as the high:
There
are normally four strings on a cello, tuned to C2, G2, D3, A3.
Scroll
= curved end of the cello
Peg = device for tuning strings (by altering their tension)
Peg box = the frame that holds the pegs
Nut = the ridge on the edge of the peg box that supports the
strings
Neck = the extension from the body of the cello that supports
the fingerboard
Fingerboard = the wooden surface against which the fingers are
pressed
f-hole = openings in the body of the cello from which the sound
emerges
Bridge = a shaped piece of thin wood supporting the strings and
through which sound is transmitted to the body
Tailpiece = anchors the strings
End pin = attaches tailpiece to body of instrument
Tip
=
the end point of the bow
Hairs = the stretched horsehair (or other material) which normally
makes contact with the strings
Wood = flexible, and usually supports the hairs
Frog = the heel of the bow
