Access Music on Apple tv

I wish to synch my entire Music from my Mac to my Apple tv First gen resulting in deleting all Music Data on my Mac. Now, will i still Be able to Access my Music thru Remote Control on my iPhone? Plus, how would I Transfer Music from Apple tv to my iPhone?

Thanks very much for advising

Unfortunately due to a limitations of the iTunes sync process, if you sync media to the AppleTV then subsequently remove it from your computer that same media will also be removed from the AppleTV during the next sync.

You could do a one-time sync, remove the media from your computer, and be sure to NEVER sync the AppleTV again but this approach is not recommened.
