I know it depends on the particular arrangement of the song, but what are some good ways to get around this?
in a certain range (bass/low) only use single notes. right in the middle near middle C, that is usually where the heart of your chord lives. Believe it or not, the melody actually should go there too, usually on a different instrument. in the higher range way above that will be sprinkles and twinkles. it's almost always a bad idea to play exactly the same chord configuration in different octaves. it's kind of like writing on a paper that's a gradient from top to bottom. if you write with the same color pen from top to bottom, on a gradually shaded page, the pen is going to have a different visual effect depending on what part of the page its on
