Surprised myself the day before yesterday by actually getting it right while driving home from work. It only lasted a few seconds, though, and I sort of scared myself. It’s an awesome sound. Haven’t been able to repeat it since, but am still trying. It was very encouraging. All the different tutorials on youtube have helped, but only to a somewhat limited degree. All they seem to have in common are they can sort of get you started, but you have to take the leap to actually figuring it out all by yourself. That, and they are filmed in absolutely filthy bedrooms.
This is definitely the most irritating thing I have tried to do yet, and that’s saying a lot. I can only try it while driving alone, and that’s sort of dangerous because besides giving me a sore throat, it also makes me dizzy because I forget to breathe, and requiring a lot of concentration my driving suffers. Also I thought I was going to give myself a heart attack yesterday so I stopped for a while.
