MUSIC KEYS

[BassHarper@xxxxxxx]

Will try to post this bit of music theory dealing with the keys again - sorry
it didn't work the last time.  I made the mistake of using tabs that didn't
work in the conversion.  Hope it works this time.

THE MYSTERY OF THE KEYS REVEALED
There are 12 tones in a chromatic scale, based on semitones.  Example: C, C#,
D, D#, E, F, F#, G, G#, A, A#, B.  The 12 tones are best displayed visually
on keyboard instruments:  piano, organ, synthesizer, etc.  A semitone is the
distance between any two adjacent notes (or keys) on the keyboard.  They can
be two adjacent white keys, or a white key and a black key.  A whole tone is
the distance between any two notes (or piano keys) having one key between
whether it be black or white.  A major diatonic scale octave contains 8
tones, based on whole tones and
semitones, starting and ending with tones of the same name.  Following is the
pattern of 8 tones within each octave, and the pattern remains the same in
each and every key:                

                        1st PATTERN SEGMENT | .            |  2nd PATTERN
SEGMENT                             
                          WHOLE  WHOLE  SEMI  |  WHOLE  |  WHOLE  WHOLE  SEMI
KEY                        TONE   TONE   TONE  |  TONE    |  TONE   TONE
  TONE
F# (6 SHARPS)   F#-G#  G#-A#  A#-B  |  B-C#    |  C#-D#  D#-E#  E#-F#
B  (5 SHARPS)    B-C#   C#-D#  D#-E    |  E-F#    |  F#-G#  G#-A#  A#-B
E  (4 SHARPS)    E-F#   F#-G#  G#-A    |  A-B      |  B-C#   C#-D#  D#-E
A  (3 SHARPS)   A-B    B-C#   C#-D      |  D-E       |  E-F#   F#-G#  G#-A
D  (2 SHARPS)   D-E    E-F#   F#-G        |  G-A      |  A-B    B-C#   C#-D
G  (1 SHARP)     G-A    A-B    B-C          |  C-D       |  D-E    E-F#
  F#-G

C                       C-D    D-E    E-F           |  F-G       |  G-A
   A-B    B-C

F  (1 FLAT)        F-G    G-A    A-Bb        |  Bb-C      |  C-D    D-E
   E-F
Bb (2 FLATS)     Bb-C   C-D    D-Eb        |  Eb-F      |  F-G    G-A    A-Bb
Eb (3 FLATS)     Eb-F    F-G    G-Ab        |  Ab-Bb   |  Bb-C   C-D    D-Eb
Ab (4 FLATS)    Ab-Bb  Bb-C   C-Db       |  Db-Eb    |  Eb-F   F-G    G-Ab
Db (5 FLATS)    Db-Eb  Eb-F   F-Gb        |  Gb-Ab    |  Ab-Bb  Bb-C C-Db
Gb (6 FLATS)    Gb-Ab  Ab-Bb  Bb-Cb    |  Cb-Db    |  Db-Eb  Eb-F   F-Gb

Note that there are two pattern segments (whole tone, whole tone, semitone),
separated by a whole tone, within the octave.  This pattern may be used to
find the proper sequence of notes in any given key.

ENHARMONICS
There are 3 basic pitch designations:  natural, flat and sharp.  The white
keys on the piano are considered natural, while the black keys are flats (b)
and sharps (#).  A flatted note is lowered one semitone, while a sharped note
is raised one semitone.  Using the piano keyboard as a reference, note that
C# is also Db that is an "enharmonic"  one tone, or note, having two names.
 Enharmonics are easy to remember: since music notation is in alphabetical
order from A thru G, and sharps raise a note while flats lower a note, it
follows that D#=Eb, F#=Gb, A#=Bb, etc.  Carrying this one step further, E can
also be called Fb, while F is also E#, and B can also be called Cb, while C
is also B#.  (Note that E & F and B & C are adjacent white keys with no black
key between.)  These enharmonics can be noted in the chart above, when
comparing
the keys of Gb and F# note that the major scales are exactly the same, note
for note, using the enharmonic names.
