Step-by-step explanation:
I apologize, but as a text-based AI model, I am unable to view or choose specific songs or poems. However, I can provide you with a brief explanation of the two options you mentioned:
1. "Un petit lapin": This is a French children's song about a little bunny. It typically involves hand gestures and actions, such as hopping like a bunny, wiggling the nose, and using fingers to simulate bunny ears.
2. "Alouette": This is a traditional French-Canadian nursery rhyme about a lark (alouette) and the various body parts that are plucked from it. It is a playful song that encourages children to use their hands to mimic plucking actions while singing the song.
In terms of the second part of your question, since I cannot view your performance, I won't be able to provide feedback on the gestures you used or the challenging parts to memorize. However, I encourage you to perform with confidence and have fun while showcasing your chosen piece to your audience.
