WordPress Themes & IFrames

I’ve just started to work with themes & I’ve tried to make a theme that would allow me to target my sub pages (not wordpress pages) in an iframe & not call on the header, footer & sidebar…but target the subpage in the iframe instead of refreshing the site. Do you get where I’m going with this? For example, I use to make simple layouts which targeted my sub pages in iframes, now that I’ve learned to make wordpress themes I’d like to keep using iframes but still use a theme! The reason for this is because I want to play music on my website & it’s really pointless to have music if when each subpage link is clicked the site will refresh & start the music over.

I tried to use the iframe code before in a previous theme but it didn’t work, I check the code it wasn’t wrong…so my question is CAN IT EVEN BE DONE like that? Have you ever seen it before!

Thanks for reading & I appreciate any help!
