This is about learning how to construct chords using major chord harmony , chord construction etc.
It's daunting to imagine you'll need to remember hundreds of chords in different fingerings all over the neck.
There are 12 major chords, 12 major 7, 12 minor, 12 minor 7, 12 7th chords, 12 diminished, 12 min7b5. And that's just the major harmony chords with no extensions or modifications (add 9 , sus2, sus4, #5, #9 etc.)
So that's over 100 main chords, with 5 positions/shapes each, adding up to about 500 chords + modifications!
But there is a quicker way! And this is how I learned all the chords I needed as a professional Jazz guitarist in the 90's.
I'll explain the basic concept, which is to understand the 3 chord types and how they are constructed using intervals.
There are only 3 types of chord:
Major
Minor
Dominant
Each of these 3 types can be enhanced with diatonic extensions such as 6th, 7th, 9th etc.
The Dominant chords are also commonly modified with non-diatonic (altered) notes that heighten the tension and anticipation. For example, These additional altered notes can turn the dominant chord into diminished and Augmented chords by adding b9 or #5 intervals.
Armed with this kind of understanding it becomes possible to construct chords as you need them by adding the correct intervals and alterations to the 3 chords you already know.
Although it is useful to know all the notes on the fret-board , it isn't necessary in order to use this chord method. Once you have learned your major scale in all 6 positions, creating chords you need using intervals within each scale is relatively easy.
So, to get started on this route you'll need to learn:
C major Scale in 6 positions
Chord Harmony in C
Chord construction
There is of course a quick and fun way to learn all this!
Learning new chords on guitar can be frustrating with out some guidance.
Most people who start learning guitar will give up when things get tough and convince themselves that they just can't do it. Hundreds of chords to learn, hundreds of techniques and lots of mental and physical challenges.
This article is not about how to play chords physically, it is about learning to play them well and being able to change between chords smoothly every time.
Most adult students don't have too much trouble learning new chord shapes. The problems begin when they struggle to change between chords quickly and accurately. This is when methodical learning techniques can really help bring you over the line.
It is only by becoming aware of a movement, that you can truly learn it.
Best way to explain is with an example method.
In the following example my student wanted to learn 4 new chords and be able to change between them quickly and smoothly.
The 4 chords: Asus2 (add 9), A minor, Dsus2 (add 9), Csus2 (add 9)
The easiest chord to start with is Asus2 so we grouped it with A minor for speed learning. This is because only one finger has to move to change from Asus2 to A minor
Both chords must have all their notes clearly audible when you pick. It is easy to accidentally mute other strings if your hand isn't positioned correctly, and you don't want to learn bad hand position.
The first thing to do is focus on you fret-board hand only (don't pick the strings at all). Carefully position your fingers softly on each note of the Asus2 chord one at a time - you don't need to press down yet because you are just thinking about which finger is placed first, second and third etc.
Now add your first finger to create the A minor chord shape. Easy!
Now repeat (chord hand only), but this time press down on the strings so you can make sure they sustain until they naturally decay.
Carefully and slowly arpeggiate ( or sweep pick) Asus2 with pick down-strokes, to make sure you can hear all the notes the chord contains.
Then add your first finger to make A minor and carefully do the same , listening to each note and how it sounds.
Now lift your first finger to return to the Asus2 chord and repeat the sound check - and so on.
Repeat this chord change 5 - 10 times without mistake - if you make a mistake, start again.
