“First Experience Of Stage Performance” Here Is The Beginning Of A Story. Complete The Unfinished Story In About 200 Words: Abir Is A Violin Learner. His Brother, Dhrubo, Is A Violin Master.

First experience of stage performance

We went to attend school cultural function in Boishak Festival. Over there we had to take part in and we got an opportunity to perform on stage for the first time for playing violin.

We could enact anything on our own decision. Our team and we decided that we took it as a challenge and looked forward to give our best. In no time our turn came and we were on stage. Forgetting all of our flaws and worries we deeply enacted our level best.

 

The audience gave me a great round of applause. It was our first experience on stage. It was a great experience. We were good at playing violin and how much we learned from our violin master Dhrubo.

This event affected us a lot, because we learnt to have more courage to perform something in front of others, even if we feel nervous or fearful before the audience. We are all of them felt fantastic and proud, because Mousumi and Abir had play very well than others of our team.

We were very excited to receive our invite to post on medium as we have been a large crowd of the platform for quite some time. Now, we had hoped that when we received an invite we had have something interesting to write about, something more experience based and interesting than our usual every day observations we post elsewhere.
