The other thing I would mention is that you mix based on the audience and what you want the listener to experience. Let me give you some examples of what I am talking about.
I listen to and play mostly bluegrass music. Here the individual performance is up front. When the singer is singing, they are in the forefront. When the mandolin is doing a solo, it gets pushed to the front. A lot of this comes from the old days when they had but a single mic on stage. The band would gather in a semi-circle around the mic. Then as a part would become the focus they move up to the mic. When they were background they would move away from the mic. Doyle Lawson and Quick Silver still do this a lot in their performances (here is a youtube clip - here they use 2 mics but I think it'll give you an idea -

I also do the recording for our church services on Sunday. We have a praise band that includes acoustic guitar, electric guitar, electric bass, electronic drums and keyboard, lead vocalist and three backup singers. When I first started doing the recordings I tried to do it like the music I had been listening to, and needless to say it wasn't working. Nobody was happy with the sound, especially me. I started talking to the leader of the praise band, and we sat together for a number of days talking about what we could and could not do while recording the service. He also lent me some CDs of the groups that had recorded the original songs they were doing. Folks like Chris Tomlin and Casting Crowns. Here is a YouTube video of the Cast Crowns song "Courageous" (

If you compare these two styles of music, you can easily see how different they are, in presentation, in instrumentation and in the mixing. After listening to a bunch of these CDs, we were able to significantly improve our mixing of the praise group. We still talk about how things can get better, from both sides of the mic.
Lastly, how you record/mix has a big influence on your final product. When I record at home, I can take my time, do multiple takes and select the best ones. I can also try different effects, different mics, move panning around, and do all different sorts of tricks. Not so when doing a 'live' mix. Every Sunday we record to a CD. One take. Two effects (chorus and reverb) and no second chances. Plus we also want the CD (which is also the signal used for our live streaming) to bring across the feel of the live environment. So we include adding in the congregational singing, the hand clapping, etc. Totally different mix from the 'sterile' studio environment.
As was said earlier, lots of different things to think about when trying to 'focus' your music. Hope this has offered some ideas to think about.
