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, 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, 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 programs that will transpose it
for you and display, play and print it in the new key
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 kinds 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 we
play music with first black key for thaat practice or playing songs as
a beginner. 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 swars will remain according to system
mentioned. If we want to sing a song in bilawal but our voice do not synchronize
with the first 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. Following is the system for
playing bilawal thaat with different notes.
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 1 notes
with cross sign (X) will be ignored and when we will play
remaining notes in madh saptak then it will become sargam of
thaat bilawal.
Note that while playing sargam we also include next saptak S' note
again to play in ascending and descending order.

Or
we can write whole sargam as S R G m P D N S’
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
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

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.
