need instruction

you don't need to know scales to get better dude....

Every song you create play harder faster and make it harder to play while making use of all the strings more.
 
Best thing you can do is get a teacher, IMO.

But since you're desperate I'll help you out a little.

Major scale = W W H W W W H

(W means whole step and H means half step)

So:

A major = A B C# D E F# G#

-----------------------------4-6-7-
-----------------------4-5-7-------
-----------------3-4-6-------------
-----------4-6-7-------------------
-----4-5-7-------------------------
-5-7-------------------------------

Note highlighted is F#, the relative minor of A major. To find the relative minor of a key, go backwards three half steps from the root note of the major key.

F# minor = F# G# A B C# D E

------------------------------9-10-12-14-16-17-
----------------------9-10-12------------------
-----------------9-11--------------------------
---------9-11-12-------------------------------
-9-11-12---------------------------------------
-----------------------------------------------

Chord progression = I, ii, iii, IV, V, vi, vii, VIII

(uppercase means major and lowercase means minor)

Major chord = major third and perfect fifth

Minor chord = minor third and perfect fifth

So:

--5---7---4---5---7---9----11---12--
--5---7---6---7---8---10---13---14--
--6---7---6---7---9---11---13---14--
--7---9---6---7---9---11---13---14--
--7---9---4---5---7---9----11---12--
--5---7------------------------------

I'll let someone take it from here as I'm not the fountain of guitar knowledge and I don't have much time.
