First, choose a song that's pretty popular. Our example will be singer-songwriter Barrett Strong's "I heard it through the grapevine." Treat yourself to the version you're familiar with
I like this live performance by Marvin Gaye, who made the song famous
Now, go to youtube and do a search for that song - but don't go right to that same version. Try to find different versions, other artists who made the song their own, who let you hear the song anew. Which ones feel "karaoke," and which ones feel original?
It's the same song, but different approaches, different arrangements, different voices make each unique (or not...)
Here's a sampling of some of the videos I found of "Heard It Through The Grapevine"
Gladys Knight and the Pips:
Creedence Clearwater Revival:
Birds of Tokyo:
Now, think about the story you're working on. What are you bringing to the story that's uniquely YOU? How is what you're creating more than 'karakoe?" The answer... that's your voice.
