Some people snort when they laugh. I am sure that you know someone who snorts when they laugh. It might even be you.
I was playing harmonica and I accidentally moved in the wrong direction. My lungs were drawing air in through the reeds while my mouth was blowing out. The sound got stuck in my nose. It was like snorting when you laugh only it was with a harmonica. It was uncomfortable but that didn’t stop me from spending the next 20 minutes trying to recreate that sound. It will never happen again. It was lightning in a bottle. It was the snort in the harmonica.
