Ilusão de Ótica

The chart has been transposed, but the video stays in the original key. The player is an iframe from another domain, and the YouTube API only exposes playback speed, which would shift key and tempo together. Use transposition to fit the singer's voice while playing without the video, or go back to the original key to play along.
