How do you know if you're singing in tune?

What frequency tuning forks are best to use to tune chakras?

• I have a set of 210.42- 136.10 -272.20- 172.06- 221.23 -194.18 -141.27 and 126.22 (hz). I herd this set described above were the best frequencys to use but then I saw a web sight saying I need to use the solfeggio frequency's instead... I thought that sense the solfeggio frequency's contain the special 528 hz tone used to heal DNA by doctors that these must be the correct frequency's to use... So out of the set I listed above top, ( i dont know where they got thoughs frequency's from) and the solfeggio set, what one is the best? Is there a third set that some would argue is the correct set but I have not herd of it yet? I realize this whole tune your chakra thing originated with the ancient vadic and hindu peoples - do any of their holy texts refer to the correct frequency's? If not dose anyone know what frequency's they used by taking an ancient singing bowl and finding out what it was tuned to or something? I hear some people use forks tuned to the planets but I dont understand how they can take a period of time like how long a saturn year is and then turn that into a frequency??? That's kind of like saying 55 years = C sharp. But if anyone used the planet frequency's to tune id like to know why also.

  I don't know how I ended up in the cycling section either. I have no expertise with this. Hope someone can help you out.
