What are some mental and physical exercises that unblock the throat chakra?

Guess it needs a thorough job, but I found that finding frequencies you can't sing to be helpful.

Like make your voice go higher/lower and find a tone your voice skips a portion of the spectrum and then focus on the frequency it skips and it energizes a distorted portion of the throat chakra.

I may resonate more with this exercise because of awfully needing it, but who knows, while it's something I found for myself I guess it can probably be helpful to someone else.
