Transposing The Pitch; Making Fine Adjustments To The Pitch - Korg CONCERT C-550 Owner's Manual

Playing

6.Transposing the pitch.

When the song you are playing contains
man y sharps or flats, or when the k ey is too
high or too lo w to match other instruments
or to sing along with, you can change the
pitch of the k eyboard so that the song can
be played in an easier k ey or at a more
singable pitch. This is referred to as the
Transpose function.
●Move the [KEY TRANSPOSE] slider to the
desired key.
The "C" note will be given the pitch that you
specify on the [KEY
TRANSPOSE] slider. The
range of settings is 11
semitones in semitone
steps (C(-5) ~ F#(+6)).
Example 1. If the [KEY TRANSPOSE] slider is
set to "F," pressing the "C" note will
produce a pitch of
. " " F
Example 2. Using the Transpose function, a
song written in a difficult key (with
many black keys) can be played in
an easier key.

G# Fm
If the entire song is four semitones
higher, the chords will be as follows.

This is much easier to play. However
if you play the song this way, the
pitch will be higher than it should be.
So, simply lower the pitch that is
produced by the C-550 by four
semitones (i.e., move the
[KEY TRANSPOSE] slider to "G#").
Example 3. To raise the key of the song by 1
semitone, move the
[KEY TRANSPOSE] slider to "C#".
TO lower it by 1 semitone, move the
slider to "B".

instruments you are playing.
be adjusted in the range of 427 ~ 453 Hz

1
cents.
1.Press the [TUNE] switch.
The indicator at the [TUNE] switch will light, and the
LED display will show the current tuning value.
2.Press the [+/UP] or [–/DOWN] switch to
adjust the pitch.
Each time you press the [+/UP] or [–/DOWN] switch,
the value will increase or decrease by one. If you
continue pressing the switch the value will continue
to change.
Hz (Hertz) : This is a unit of absolute value used to
indicate pitch. When tuning instruments to each
other, the middle A note (A4) is used. Usually
A4=440Hz, but the standard pitch has differed by
area and by historical period, and recently there is a
tendency to tune to a slightly sharper pitch (A4=441
~ 444 Hz).
cent :Cents are the smallest unit used to indicate rela-
tive pitch. A semitone is 100 cents, and an octave is
1200 cents. 1 cent is a very small amount, and a
difference of +/–3 cents should not normally cause
any problem.
