there are lots of people out there on the Internet who claim that "528 Hz" will heal DNA. However, I've never really seen any real clear evidence of this. If you have some I would be very much interested in reading it
As for what you can do with these frequencies, you might try different octaves of them i.e. the base frequency multiplied by two, x4 x8 x16 x32 x64 etc. etc.
