does my fire tablet have bluetooth
First, you need to have a Kindle Fire HD or HDX as these are the Kindle Fires that have bluetooth. The very first generation doesn't have this capability. (If you don't know which tablet you have, see this article.). Second, you need to have a bluetooth keyboard or other device, like headphones, speakers, or earbuds. This is a picture of a Jawbone earpiece I've successfully paired to my Kindle Fire and been able to listen to music with.
