You know what chords are right? They are the one's responsible for developing songs because songs are not just mere notes strung together like in the case of whistling tunes or humming the soundtrack from jeopardy.
First of all, try to fixate on only two chord figures: figure1, or the F major chord and figure 2 or the Bb (flat) chord using the 5th string - 1st fret.
If you've tried several Beatle and Queen songs lately then here's how the whole scenario goes: these guys always manage to juice out and sun-dry a single chord, meaning, they can create various characters or vibes out of one single chord! How? Do the numbers 6, 7 and 9 ring a bell? Guitar lessons always present tricks such as this one: one chord can have different sounds if you use or add notes from the respective scale.
For the A chord, you may use the A major scale.
The technique here is, label the note that represent Do (or in this case your A root note) as number 1, Re for as number 2, Mi as number 3 and so on; although in this case, the most significant notes to label would be the 6th, 7th and 9th.
Make sure not to use the long scale method for this instance so that when you need to reach out for these notes, you won't have a hard time creating broken chord figures.
They may look better and more intricate ('cause in fact they are) but sometimes, it's not practical to make things difficult when you're hitting the same correct notes anyway.
Now that you've labeled and pointed out where on the neck are the 6th, 7th and 9th notes are located, you can now proceed exploring the sounds that these notes will add to your mundane major chord.
Thus, the A chord can now be called A6, or an A major chord with a prominent 6th note, A7 (or even A major7) and A9 (obviously, it's the 9th note that's emphasized here.
There are even variations like A6+ (plus) 9 or A7 sustain or even D7+9.
Other variations will involve the bass string's root notes as the main note to be emphasized.
You ay try the following as well: Do a basic D chord on the 2nd fret - lead string area with the 4th string (open D note) as root note.
Now place your thumb over the F # note on the 6th string and strum.
The sound is neither B minor nor D major, albeit there's a hint of both but you keep trying to identify what note made it different.
The chord you just did is now called as F #/ (over)D.
It's like a fraction only better.
This formula can be applied to your other favorite chords, even the minor cluster.
Experimenting with notes and delving into guitar lessons can only make you better so don't be afraid to keep trying all the weird stuff like dropping tune on the E note, playing power chords with open strings under it or just exploring the jazzy sound of the 6th, 7th and 9th notes and incorporating them into one of your songs.
Have a blast and keep on learning!
