The sound of one hand clapping
It is definitely impossible to clap with one hand. However, it can be possible to make sound, if you use your body. That is to start thinking of transition.
People usually make sound with their hands clapping, and they are accustomed to doing it so. I think it is one of the stereotypes in our life, which means people are still trying to find perfect preparation of sound. But there is no perfect preparation and correct answer in the world.
Even though you are not perfect, just show what you are and present your way to the world. The world does not ask you to bring routine ideas but your own novel ones. Do not be afraid if you do not have things in common.
