Crevs,
Hey man, good to see you on here again. I started out playing the minor pentatonic scale up and down just as it's written and let me tell you...ITS BORING!!!
You have to be able to jump around the scale and do bends, hammer ons and slides to vary it up a bit and keep it interesting. Playing scales or improv along with a song is a lot like a relationship. If you don't keep it interesting the partner (Your audience) will get bored and leave.
I started out playing along with backing tracks. I would just do the same one over and over and see how I could change up my scales/lead riffs each time the backing track played.
The extended scales are what set me free too. It's like going from a Scion TC to a BMW 750Li.
The extended scales give you more range and wrap around the fretboard like a spiral.
....for example here is the regular Am Pentatonic on the left VS the extended Am Pentatonic on the right:
-5--8-------|-------------10-12//15--------------------------------------------
-5--8-------|----------8-10//12------------------------------------------------
-5-7--------|--------7-9-------------------------------------------------------
-5-7--------|-----5-7//9-------------------------------------------------------
-5-7--------|-----5-7----------------------------------------------------------
-5--8-------|-3--5//7---------------------------------------------------------
See how many more notes you have in there? The "/" indicates a slide so for the first one it would be: 3-(hammer-on)-5-(slide into)-7
Using the Extended version will give you more tonal options when you're soloing/playing lead.
From any point you can convert to another type of scale (Phrygian....blues...major) to get a different sound that matches the chords/chord sequences that are being played by the rhythm instrument or backing track or singer.
You can also use the extended scale to complete a spiral wrap around the fretboard to reach the higher octaves.
What I mean by this is...you see where the extended scale ends on the high-e string at the 15th fret?
e|-------------10-12//15--------------------------------------------
B|----------8-10//12------------------------------------------------
G|--------7-9-------------------------------------------------------
D|-----5-7//9-------------------------------------------------------
A|-----5-7----------------------------------------------------------
E|-3--5//7---------------------------------------------------------
Well, all you do is after you get to that note on the high-e string....jump down to the low E string at the 15th fret and start the sequence all over again. The connecting sequence looks like this:
e|---------------------------------------------------------
B|-----------20-22------------------------------------------------
G|--------19-21-------------------------------------------------------
D|-----17-19//21-------------------------------------------------------
A|-----17-19----------------------------------------------------------
E|-15--17//19---------------------------------------------------------
Of course this particular example would be used on a shredder style guitar with 22-24 frets...but you get the idea right?
