Anywhere from alpha to delta, 14-4 hz. You can find binaurals easier on Youtube, though, but they often have meditational music with them.
I'd suggest starting with high alpha (14-10) and lowering gradually to 7-4. Starting too low too fast can cause headaches. Also, try to make it raise back up to alpha near the end of the file, since it can help subconscious memory better than jerking awake.
If you're using a music program, a list of the frequencies of notes is here: [url]http://www.phy.mtu.edu/~suits/notefreqs.html[/url]
