See, I'm a big fan of Kemono no Souja erin so I'm writing a fanfiction but I want to have the songs that appear in the anime playing in the background, but no one really understands them since the words are all in japanese so I wanted to record the song(piano) and play it like that but I don't have the sheet music...Can anyone help?
