Re: Issues with song structure/arrangement.
Username relic has the right idea. Make 64 bars of an evolving progression. Just add a new repeating pattern every 8 bars. Then chop it up and rearrange it by ear. You'll probably need to listen to your track over and over 300 times and make iterative changes a similar number of times. It helps if you know how to harmonize instruments. The other alternative is you can go out and cover 10 of your favorite songs. Just drag the whole wav of the original song right into the pianoroll of your daw, and then line up your cover patterns with the original song so they sync up. After you've done 10 covers, you'll have your own style of arrangement that is derived from the top artists, but it will be more like your own personal blend.
