Extended Guitar Chords - Clarence or Rookantha? How To Build Chords

 Although Sinhala songs in 70's had simple three chords also known as family chords played throughout the song now we hear some extended chords in new songs.You can also find some advanced chords in Rookantha's Songs.I like both of them.They  are two different styles.Sometimes simply the best.But It's nice to grow your chord vocabulary with extended chords.

Since  articles or lessons available in this topic are rare  I thought it would be useful to post an article about extended chords and the basics of building chords.Once you get the idea you can build any chords yourself.

Chords are built off the notes of the  scale. Here is a chart of some commonly used major  chords, arranged to show how they build up –
Major – 1 3 5
7th(dominant 7th) – 1 3 5 b7
Maj7 – 1 3 5 7
9th – 1 3 5 b7 9
Maj9 – 1 3 5 7 9
11th – 1 3 5 b7 9 11
Maj11 – 1 3 5 7 9 11
13th – 1 3 5 b7 9 11 13
Maj13 – 1 3 5 7 9 11 13
(For minor chords – replace the 3 with a b3. For example: Min7th is spelled 1 b3 5 b7 11)
For extended chords, the tonality really hinges on the seventh note.
The most common misunderstanding in chord building is what ‘maj’ means. ‘Maj’ refers to the seventh note in the chord. An Amaj7 has a 7 note in it (G#). Dopminant seventh has b7th note.So A7 has a b7 note (G).
It takes practice to master building chords. It takes actual thought – not just memorization. However, the payoff is being able to look at any chart and never be confused. Sure, you may not actually know the chord you are looking at, but with practice you can easily build it.
Start dissecting the chords you know. What notes are they made up of? What order are those notes in? Grab a book with some interesting chords, and practice constructing them.This is a topic that can get confusing to beginners.If you have a question don't hesitate to ask.
