I found the pitch of my tinnitus by using a piano. I just tried the different keys until I found the ones that are lower and higher pitch than the tinnitus. It was not very difficult, especially when I found the pitch that was higher. the comparison was very noticeable. I thought I had very poor pitch recognition, but not so.

My tinnitus was real loud last night, especially right after I had a drink of water. I wonder if the cool water, straight out of the tap, has any effect. I know it made the back of my mouth feel cooler.
