Well I guess I got a pretty good start with A already. I'm gonna post what I already had For A,
Then just put a couple practical things you can do maybe not so much just using the 3rds but
triad or more that the 3rds were derived from. Remember that part of what you're trying to
do here is see the whole chord that can be used as well. Refresher from earlier post.
//////////////////////////////////////////////////////////////////////////////////////////////////////////
A is a little different because of the 2nd string being tuned differently. 3rd is on same fret as 1st. When it goes minor it drops to only being 1 fret down. Otherwise the same M m m M M m b3b5 sequence.
I maj II m III min IV Maj V Maj VI min VII b5b3

Open A shaped based 3rds. 3rds are located on strings 2 and 3. Notes in ( ) complete triad.

Here a couple little things that aren't too hard. (my constant goal) These would fall in the
"beyond" part of post heading. Something you can end up seeing as you see the 3rd's
patterns.

Important to make the open A barred with 1st finger. Then all you have to do is lay middle
and ring down to get 2nd chord.. I usually get 3rd chord with 1-2-3 fingers. This is the same
thing we did with D, Just in A. The song would be holding on A chord and you just go
between two A chords with the middle step added. You can mix it up. Go down,
Maybe just go back and forth between the first 2 chords a couple times then up to the
5th fret. Play around with it.
Add a step to it. for 4th chord all you have to do is lay down pinky

Sorry 12 fretters but if you just get 2nd and 3rd strings it works. On 2nd to last chord
again your just laying down pinky and other fingers remain in place. Notice that the main
feeling of movement is coming from 2nd string.. You could change that to 3rd string.

For ease and time lets just give 3rd string more emphasis between 2nd and 5th fret.
So you can find notes to add in to get a feeling of movement that aren't hard to do.
Folks this is probably cheating! A jazz miester could very likely have a whole nother
chord shape instead of just adding a note to exsisting chord. But it works and adds a lot
for players at my level.
I'm not gonna redo all these diagrams but do this. Just pretend, or actually, play like a 12 bar
blues. (even though these have major feel) when it's time to go up to the D chord just scoot
the whole pattern up 5 frets to 7th, and do the same thing, when it's time for E start at 9th fret.
Of course you'll run out of room, but that give the idea of moving patterns around, just like we did
with D.
Time to go, but I think I need to do one more on this thread to show caviats and little interesting
things that are going thru my head that might make you think more. When you strip a chord down
it is less harmonically bound

Sorry that just was a more sophisticated word than I'm used to.
But anyway it's less defined and can go more directions or could be a substitute for multiple chords.
One more later. (didn't I already say that?)
