Hi I have been playing guitar for about 1 year. I know scales, modes and theory, chord constructions & transposing, modifying, extending & stuff. All the general things. My technique is also very good. Now I need some help with: 1- Making melodies & songs. 2- Want to know what is the key of a song, and how to determine it. 3- How to find the keys for chords, or to tell what chord will go well with what without actually trying em out. Like Am, G & F are in one key, but I dunno how? 4- How to tell what notes go well together, like in major scale, 1st, 5th etc. intervals sound good together. Thats all for now. Therez a lot of questions on my mind. Cant remember them all right now. Will post up as they come to my mind. For now, plz explain the above montioned points. Thanks.
