Transposing Or Scale Changing
Note:
Transposing option in keyboards or Scale
Changing option in harmonium is same.
Transposition: Changing Keys
Transposition, or changing the key of a piece of music, can be
useful and is sometimes necessary to make music more sing able or
playable. Music is transposed by raising or lowering every note by
the same interval. Changing the key of a piece of music is called
transposing
the music. There are many reasons why you might want a piece to be in
a different key. There are also some ways to avoid having to do the
transposition yourself, but learning to transpose can be very useful
for performers/singers, composers, and arrangers
Why Transpose?
The
most common reason for changing the key of a piece of music is to
put it in the right key for your vocalists. If your singer or
singers are struggling with notes that are too high or low to sing, changing
the key to put the music in their range will result in a much better
performance. Instrumentalists may also find that a piece is easier
to play if it is in a different key. Players of both bowed and
plucked strings generally find fingerings and tuning to be easier in
sharp keys, while woodwind and brass players often find flat keys
more comfortable and in tune. Instrumentalists with transposing
instruments will usually need any part they play to be properly
transposed before they can play it.
A good
electronic keyboard or scale changer harmonium will transpose for
you. If your music is already stored as a computer file, there are
several transpose programs that will transpose it for you and
display, play and print it in the new key for your singing or
listening.
Choosing Your New Key Or
Scale
Before
you can begin transposing, you must decide what your new key will
be. This will depend on why you are transposing, and what kind of
vocalists and instrumentalists you are working with.
1. Transposing scale
beginning from first white key
Usually we start thaat bilawal with first black key which is 'S'.
Normally for thaat practice or playing songs as a beginner we start
with first black key. When we become perfect keyboard or harmonium
player we can use any key for playing thaat bilawal but the
arrangement of achal, tiver and komal swar will remain
according to system mentioned earlier. If we want to sing a song in
bilawal but our voice do not synchronize with the first black note
then we may try other notes according to our voice pitch. We can
play thaat bilawal songs with any key with transpose option and
still song will not effect. In the following diagram we have
transposed thaat bilawal from first black note to first white note
and still thaat bilawal will remain bilawal thaat.
Diagram.1 Building Thaat Bilawal Sargam From First
White Key
Note: -
We can select any key as our Sa and from that position of Sa our key
combination will change in each below given diagrams. Some person
cannot sing in loud scale so; the musician will select suitable
scale for them. Selecting scale means transposing or selecting first
note. In madh saptak of diagram 3, notes
with cross sign (X) will be ignored and when we will play
remaining notes in madh saptak and it will become sargam
of thaat bilawal.
Note that while playing sargam ascending and descending we also
include next saptak note S'.

Thaat Bilawal sargam in ascending and

2. Transposing scale
beginning from first black key (default key)
Diagram.2 Building Thaat Bilawal Sargam From
First Black Key
We
can select any key as our Sa and from that position of Sa our
key combination will change. We have selected first black key as
a default key to play harmonium. From now we will always
select first black key as our starting point. Now our key
combination will become as given below:
S r R
g G m
M P
d D
n N S'
1 2 3

Note: Sa is always achal or qyme swar. The
first swar or key
attached just after Sa
is always komal ray
shown with cross (X) and with note no. 2, then
tiver ray with capital
R, komal Ga, then tiver
Ga, komal
Ma then tiver Ma, achal Pa, then
komal Dha, tiver Dha, komal Ni, tiver Ni,
then achal Sa as S’.
Or we can write whole
sargam again as S R G m P D N S’
Again Thaat Bilawal sargam in ascending and
descending order
Arohi : S R G m P D N S’
Amrohi: S’ N D P m G R S
3. Transposing scale
beginning from second white key
Diagram.3
Now we
have selected our first key from 2nd white key for playing a
song or harmonium We can select any key as our Sa and from that
position of Sa our key combination will change in each diagram.

Note : Sa is always achal
or qyme sur. The first
Sur or key
attached just after Sa
is always Komal Ray
shown with cross and with note no. 2 Then
Tewar Ray with Capital
R,
Komal Ga Then Tewar Ga, Komal
Ma then Tewar Ma, Achal Pa Then
Komal Dha, Tewar Dha, Komal Ni Tewar Ni,
Then Achal Sa as S’.
If we do not play notes with cross sign in diagram 5 then it will also
become another Thaat.
Or we can write whole sargam again as S R G m P D N S’
Again Thaat Bilawal sargam in ascending and descending order
will be same.
Arohi : S R G m P D N S’
Amrohi: S’ N D P m G R S
It is proved from above three examples that whatever note is
selected as initial note to play sargam, the corresponding notes
will change according to a fixed system of achal, komal and tiver
properties.
Transpose option of keyboard and
harmonium:
For keyboard
learners the option of transpose in keyboards have made it
easy to change scale according to voice pitch of singer or
song. Note that by default we have selected our Sa as
first black key throughout this website.
In scale changer
harmonium use scale changing option. Now there is no need to
learn playing from every white or black key. Only learn to
play music from first black key and change your required
scale by transpose option. You are required only to learn 10
thaat which begin with first black key therefore transpose
option have made scale changing easy for singing.
