# Thread: Basic Theory of a Chord in as Short and Simple as possible

1. ## Basic Theory of a Chord in as Short and Simple as possible

Ok so here goes
BASIC THEORY OF A CHORD
in as short and as simple as possible with references to intervals and counting notes

i've written this in as simple language as possible in hopes that even a beginner would be able to understand it

Chord theory:
Lets take the C Major scale for example
C D E F G A B C (lets say our C is at 100 Hz)
Since its a major scale all notes are referenced to as diatonic notes
D=M2 (major second)
E=M3 (major third)
and so on
however F G and high C (200Hz) will be denoted by P4 P5 and P8 called perfect notes cause they do not require a third note to complete the chord
now comes the fun part

to make a dyad all you have to do is play the root note C (since its the scale of C) and any ONE of these three notes
your standard power chords like A5 C5 are made using this.. they are just the root note with the P5 in that scale

for this you will have to know your notes

Counting notes:

when I move from C to C# its called a half step or semi tone and denoted by h (one fret on the guitar)
and from C to D is called wholetone or wholestep (two frets on the guitar)
[quarter is what we drink :P]

in music there is no E# or B# so distance between E and F or B and C would be a halfstep whereas for any other diatonic note it would be a wholestep(w)

There are four types of triads
Major
Minor
Diminished
Augmented

So the following formulae apply to make a chord

Maj- 1+2w+1.5w
So your CMaj chord would have the notes C,(C+2w),(C+3.5w)
Which is C E G

Min- 1+1.5w+2w
Therefore Cm will have the notes C D# G

Dim- 1+1.5w+1.5w
Therefore Cdim will have the notes C D# F#

Aug- 1+2w+2w
Therefore Caug will have the notes C E G#

Now you can play power,major,minor,aug and diminished chords without having to refer a chord chart!

I didnt overload the thread with details cause it would cause a lot of confusion for beginners
And this thread was requested by a person just starting guitar so I didn’t wanna put him off

okey dokey

9. well let my try hope you get this...

a chord is nothing but playing more than 1 note together...

there are 3 types of chords diads,triads and 4 note chord...for guitar for piano there are 7note chords also...

For chords you need to have a strong scale theory

...
Here's a formula for major scales
wwhwwwh
where
w=whole note
h=half note.
(a to b= whole note)
(a to a#=half note)
(b to c#=whole note coz 'c' doesnt have a flat)(in whole note there should be a gap of 1 note whereas in half note there should nt be any gap between the notes.,as in the note nxt to it) and so on and so forth
for eg if you want to know the chord 'c major'
then first write the 'c' major scale notes
first start writing the scale with that particular note only .over here 'c'
by applying the formula
wwhwwwh
c- d-e- f-g-a- b|c
1-2-3-4-5-6-7 |c

c to c is one octave
here according to the formula

w(c-d)
w(d-e)
h(e-f)
w(f-g)
w(g-a)
w(a-b)
h(b-c)

so take the alternate notes from the 'c major scale i.e (c-e-g)(1-3-5) this is nothing bt c major chord (triad or 3 note chord) if a add the 6 note i.e(c-e-g-a)it will become cmaj6 or c major 6th chord,...
same with all the other notes

coming to minor scales
same as major scale just flattened the 3 rd ,6th and 7th note
i.e
c-d-eb-f-gb-a-Bb-|c
then cminor would be
c-eb-gb,...and cmin6 c-eb-gb-a

this thread is super-teaching! [my own word! ]..

11. hey komal ...m sorry 4 the layla thread...i will be posting some comments after completing my 2nd internal exams ...for the mean time ...how to play a 7 note chord....its too simple ...just play a 3 note with one hand and a 4 note with the other...but then the notes should match otherwise...it wont be consider a 7 note ...

12. half diminish is a 3note chord whereas full diminish is a 4 note ...there are advance chords also...but they are not used in regular songs...you will need them in playing jazz....for eg Bm7b5...which is called Bminor 7 flat 5...this means in Bminor7 chord flat the 5th note....i know its bit tricky ...will explain you later...oye you wont get this info's everywhere...i gotta pay me fees
