ACCIDENTALS
Accidentals are musical signs
that alter the pitch of a sound. There are five types of accidentals and each
of then perform different functions, they are;
·
Sharp
(
): a sharp increases a note by
a semitone. The increase is represented by adding the sharp sign in a power
form to the note that has been increased. For example, when C is increased by a
semitone, it becomes C
.
·
Flat
(
): a flat decreases a note by a
semitone. The increase is represented by adding the flat sign in a power form
to the note that has been increased. For example, when E is decreased by a
semitone, it becomes E
.
·
Double
sharp: a double sharp increases a
note by a tone. The increase is represented by adding the double sharp sign in
a power form to the note that has been increased. For example, when C is
increased by a tone, it becomes C
.
·
Double
flat: a double flat decreases a
note by a tone. The increase is represented by adding the double flat sign in a
power form to the note that has been increased. For example, when D is has been
decreased by a tone, it becomes D
·
Natural: the
natural sign restores a note that has previously been affected by any of the
above four accidentals to its original pitch. For example, if A has been
decreased by a semitone, it becomes A
, for
it to be restored back to A, u add a natural sign.
A word of caution; in
text, the accidental follows the letter, as in A
and A
. On the stave the
accidental precedes the note head.
When an
accidental have been written, all other notes which are of the same pitch (or
same position in the stave), are also affected by the accidental, but only
until a bar line is drawn. Here’s an example:
1
is
natural because we haven’t put any accidentals
2
is
flattened by the flat symbol
3
is
also flattened by the symbol from number 2
4
is
natural because the bar line cancels the effect of the flat
5
is
flattened by the accidental symbol
6
is
neutralized by the bar line
TONES
AND SEMITONES
A semitone is the shortest
distance between two notes. A tone is equivalent to two semitones. Amongst the
musical alphabets, natural semitones occur between B&C and E&F. A tone
exists between every other alphabet. Since a tone equals two semitones, that means
one can get semitones from the other alphabets where we have tones,.
A
slur is used to show the presence of a semitone between two notes.
KEYBOARD
SKETCH
The keyboard is a percussion
instrument. It is made up of sets of black and white keys. The white keys are
called naturals. This is because they are labelled naturally with the musical
alphabet. The black keys derive their names from the white keys. The black keys
are arranged in sets of twos and threes. The first white key before the set of
twos is labelled C. The distance between two keys on the keyboard is a semitone
ENHARMONICS
The ability to write the
same pitch in many ways is called enharmony. When an alphabet is having more than one name,
the other name is called en-harmonic equivalent. The complete set of accidentals and their enharmonic equivalents
follows.

Very cool.
ReplyDeleteI can’t believe focusing long enough to research; much less write this kind of article. You’ve outdone yourself with this material without a doubt. It is one of the greatest contents. Extratorrent
ReplyDeleteYes i am totally agreed with this article and i just want say that this article is very nice and very informative article.I will make sure to be reading your blog more. You made a good point but I can't help but wonder, what about the other side? !!!!!!Thanks small gaming keyboards
ReplyDeleteIn many cases, you have situations where the physical keyboard is used to make use of the keyboard onscreen. But in most cases, best keyboard for programming it's the mouse that is used to operate the virtual keyboard.
