Hi ilzho,
One way to play music from iTunes on your computer would be to use an Apple TV and AirPlay Mirroring, if your MacBook Pro is capable of it. See this page for information -

You can also share your iTunes library from the MacBook Pro

Again you would need an Apple TV to share it to.
You can also, if the TV supports HDMI input, connect the MacBook Pro directly to the TV and use it as your sound output.
Thanks for using Apple Support Communities.
