i've always loved playing. i've been on the clarinet and the trombone. however, the one instrument that gave me the most trouble (to this day i might add) is the guitar. I get chords, but i can never understand how a scale works and how it works with chords. it drives me nuts.
It's because the layout doesn't apply to any other instrument. With guitar, it's better to learn notes of the scale as numbers instead of letters. For insance, the pattern for a minor pentatonic scale is:
1,3,4,5,7
Knowing this pattern is much easier than trying to remember the notes of 24 different scale positions.
Major chords are always 1,3,5
Minor chords are always 1,b3,5
Then you can spice them up with 7ths, 9ths, 13ths, 6ths...whatever you want. The "8th" note in the scale will be the same as the 1st at one higher octave.
Maybe this will help?
