Natalia, I recorded this video by placing my cellphone on a book beside the piano and then played. I am not trying to be a funny guy, but the best way to have a good arrangement is to write it yourself, put it in the key that best suits your voice and then play it yourself. 😊 I sometimes use synthesizers to add strings, rhythm, drums, brass or whatever, but I did this with acoustic piano. I am just fortunate. For me, music reveals the heart. I can only hear these songs a certain way. You can start with a lot of notes and then remove what doesn't sound right! 😊))))) Is this song within your voice range? Very easy to not sing and only play the background, but it will be awhile. I am currently swamped with a new job. 😊
