I am not part of the organization but I follow it very closely. I also make music and someday I will participate doing some cover.

What I know is that only own performances are allowed. You can not upload a video with someone else playing, you have to be yourself who plays the song (that is, you must appear in the video while playing or singing).

In the video you must mention 3 things: the word "openmic", what week you present yourself (currently it would be week 92) and what is your account name in steemit.
Then you do your magic on the piano and that's it. The song does not have to be original. You can present covers but the original songs I think have a separate prize.
The truth is I have not found out much, but I know I'll do it soon because I also want to participate.

You should definitely participate. I have heard some melodies that you uploaded and I love them!

Thank you so much :D I think i will try it out and participate for the next open mic week :D Hahaha - "Then you do your magic on the piano and that's it" Thats so cool! Thank you :D Have a nice weekend! P.S. I would love to see your performance for the open mic week too! :)
