I've know about chords but scales is something I have not ventured into. I don't know what they are. I'm sure I can find out via internet but maybe give me example.
Scales 101 would be the C major scale - no sharps or flats from one octave to the next. You know "DO RE MI FA SO LA TI DO" don`t you? Start at any C note on the fretboard, go in a linear fashion (straight up the neck) or from one string to the next. Do, Re, Mi, etc. will = C, D, E, F, G, A, B, C. That`s the C major scale. There`s way too much to go into with scales (or music in general) but you`ll learn as you go along which scales have notes that are sharp or flat. From there you can learn about roots, 3rd`s, 5ths, 7ths,etc. and how to make chords as well as how to form more scales. My best advise would be to read everything you can about every aspect of music theory. The more you understand about music, the easier it`ll be to understand the guitar, or any instrument for that matter.
