I do need a little help to figure out what song I should do for a piano basically. Let me know what song you want me to play. ( I did America music in 2014 even dress like the flag) I don’t mind doing any other America song.
You could do a medley of songs. They’re always impressive and appeal to almost everyone. The only thing I’d say is that they take a lot longer to learn, but you have six months so you should be all right.
I reccomend this one by Amosdoll or this one by Samuel Fu. You can use any YouTube to sheet music transcriber to get the music, I reccomend this one.
