This is not made with Synthesia but instead is made to look like YouTube Synthesia piano tutorials. Everything is this is made by me.
The audio is from a project I made on BandLab: https://www.bandlab.com/jthecreator_gvo/iphone-opening-ringtone-cover-for-2-minutes-bf5e44ea?revId=4d20d7eb-3a8f-ed11-9d7a-000d3a3eed2a I drew the notes, background, and the piano keyboard too.
