Hi there Andrew,
I'm new at writing music with the guitar and just had some questions. I was wondering, firstly, where would be a good place to start? Ive already got a rhythm in my head and on paper (somewhat) but im not sure for instances what other Power Chords I should be using to make it sound good. So far the song is in F#m and Im using the F# Power Chord (PC) and the E PC. Im not sure exactly as to which other ones would sound good. Im not asking for you to tell me exactly which to use but a way that I can learn to ID these combos myself. Secondly, Im curious about Scales and Modes. Im not exactly sure yet as to how I can see which Scales or Modes would be good for Melody or Lead guitar in my piece. I've know quite a few of them when Im playing them but im not sure how to integrate it in my music. If you can tell me again, not which to use only, but also how I can ID which of these scales/modes go with what key/chord progression/etc.
Thank you and take care.
