I had a cute idea tonight and decided to film it. I took my camera ona "tour" of my house and shot myself tapping my fingernails on many different surfaces- the soft material of my couch, my entertainment center, my washing machine, to name a few... I'm pleased with how many different sounds I was able to create with my short, rounded fingernails just by playing on different surfaces. Some are soft and muffled, while others are sharp and exciting.
