A chord is a combination of three (or more) notes played at the same time.
All chords are formed by playing simultaneously three or more notes,
according to definite rules.
PLEASE REVISE Harmonium Lesson 2: The Basics. Keep the keyboard diagram in
view. Please remember, once again, that any key can become a Sa; but we
have assumed the first white key to be the Sa (S), for convenience and
convention, simplicity and uniformity.
CHORD: TYPES and SYMBOLS. Out of a very, VERY large number of chords, we
need to do only very, VERY few of those. To avoid any confusion and
conflict of symbols, I have entirely Indianised (Indianized?) the names of
the types and symbols of the chords. Later on, in a separate article, only
for your information, I will present you with the comparative names used
in this Indian syatem and those used in the Western system.
Chord Type 1: Major Chords. Symbol V. A major chord is formed when we
simultaneously play three notes S-G-P or an equivalent combination. Let me
explain by assigning key numbers, calling Sa (S) as key number 1.
Note: S key number: 1
r .......... 2
R .......... 3
g .......... 4
G .......... 5
m .......... 6
M .......... 7
P .......... 8
d .......... 9
D .......... 10
n .......... 11
N .......... 12
S' .......... 13
r' .......... 14
R' .......... 15
g' .......... 16
G' .......... 17
m' .......... 18
M' .......... 19
P' .......... 20
So, to play the major chord S-G-P, you will play key numbers 1-5-8.
This major chord is called S major. Using the symbol 'V' for a major
chord, S major chord will be written as SV.
Similarly, the major chord "rV" will be formed of the following notes (to
be played all at a time): r-m-d. How can we say that? Like this: Now, r is
key number 2. So the new set of three keys [in the relative distance
1-5-8] will be 2-6-9. The keys 2-6-9 represent the notes r-m-d. Here is
the complete list of the major chords we will use:
------------------------------------------------------
S major chord, symbol SV, key# 1-5-8, notes S-G-P
r major chord, symbol rV, key# 2-6-9, notes r-m-d
R major chord, symbol RV, key# 3-7-10, notes R-M-D
g major chord, symbol gV, key# 4-8-11, notes g-P-n
G major chord, symbol GV, key# 5-9-12, notes G-d-N
m major chord, symbol mV, key# 6-10-13, notes m-D-S'
M major chord, symbol MV, key# 7-11-14, notes M-n-r'
P major chord, symbol PV, key# 8-12-15, notes P-N-R'
d major chord, symbol dV, key# 9-13-16, notes d-S'-g'
D major chord, symbol DV, key# 10-14-17, notes D-r'-G'
n major chord, symbol nV, key# 11-15-18, notes n-R'-m'
N major chord, symbol NV, key# 12-16-19, notes N-g'-M'
-------------------------------------------------------
Similar sets of notes will apply in all the three octaves. So much for
the major Chords.
Please note:
WHATERVER KEY IS YOUR Sa, the major keys
will retain their names (like, for example, R major chord),
will retain their symbols (like, for example, RV),
will retain their key# (like, for example, 3-7-10),
will retain their notes combination (like, for example, R-M-D).
In the Part III of this series, we will take up the Minor Chords.
