Article: Harmonium Lessons - Chords: Part II: Major Chords

 
By Haresh Bakshi
 
  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.
