I just got off the piano, and had the idea for this thread. Here's the concept: if you have a synthetic scale that you'd like to share, then post it. Explain, if you can, what was going through your mind when you made it up. Does the scale harmonize? Is it the same ascending as it is descending? Is there a tonal centre? Perhaps it just sounds cool. Anyway, let the games begin! C D# E F# G G# A# B This is what I was working on right before I made this thread. The idea is to take the I and iii chords of a major scale and add a few notes so that instead of having just a C major and an E minor, we get C major, C minor, C diminished, E major, E minor, and E diminished. There's a bunch of goody goody chords in there, but I'm too lazy to find and name them all at the moment. I haven't had the chance to experiment with this scale too much, so I can't say much on how it resolves and whatnot. C D D# E F F# A A# Another octatonic scale. I drew inspiration for this one whilst watching Purple Rain. There's a little part in "Computer Blue" that has this chromatic thing going on. I picked up my guitar, played three chromatically consecutive notes on the E string, moved up to the same fret on the A string, did the same, and then onto the D string, same fret, another three chromatic notes to complete the octave. After playing around with this for a while, I decided that the sixth mode had the strongest tonic gravity. The original scale would have been this: C C# D F F# G A# B I asked a couple of guys at school what they thought of it, and they agreed that the sixth mode sounded the most resolved, so that became the final product. Edit: Now that I revisit it, what I had originally sounds more resolute. Perhaps I was playing something that emphasized that perfect fifth that day. Any thoughts?
