mute(s)
on
|
a
damper is attached to the bridge to mute the sound
|
con
sord
(Germ. mit Dämpfer)
|
con sord
mute on/off speeds
marked piano
marked forte

There
are two types of mute: the wooden mute, which is placed on the bridge,
and the sliding plastic mute, which is permanently attached to the
strings. Be sure to allow sufficient time for the player tp put on
or take off a mute! Mute on can make unwanted noise on the cello. |

natural
harmonics
|
the
string is lightly fingered at a nodal point to produce a "fluted"
sound
|
The
notation of natural harmonics is often inconsistent. Frequently
it is either just a circle over the note, thus:

or the
word harm, or indeed a diamond notehead to indicate finger
position, or some combination of the above! To be completely accurate,
a harmonic would be notated thus:

Here,
the large round notehead indicates the fundamental (open G-string
in this case), the diamond notehead indicates the finger position
and the small note in brackets is the resulting sound. (However,
cellists would probably regard this as over-fussy for a straightforward
natural harmonic).

natural harmonics
|
Natural
harmonics are strong on the cello. The extra length and thickness of
the strings means that they are more reliable than on violin or viola.
The main
nodal points on a string are as follows:
1/2 (gives 8ve above open string)
1/3 (gives 8ve+5th above open string)
1/4 (gives 2x8ves above open string)
1/5 (gives 2x8ves+maj3rd above open string) Further
nodes exists over the end of the fingerboard, of which the strongest
gives 2x8ves+perfect 5th above open string.
There
are intermediate nodes, which produce unstable harmonics.
|
|
artificial
harmonics
|
the
string is stopped normally, and then fingered (with the little finger)
at a point a 4th or a 5th above the stopped note
|
The
same notational practices apply for artificial harmonics. Note
that in this case:
the first will produce a note 2x8ves above the stopped note, the second
an 8ve+5th above the stopped note. Often a small notehead in brackets is
used to indicate the sounding result, as in the example above. Where the
word flag (= "flageolet") is written over the note, a
whispered bowing might help the 'whistling' sound, but this instruction
can also mean, quite simply, 'harmonic'.

artificial harmonics
|
It
is possible to add vibrato and to play melodic lines in artificial
harmonics, but both techniques should be used with care.
