How you play affects the stars and score you receive. Stars range from one silver star to three gold stars per section. To earn gold stars, you need to play everything right with good timing.
You can also keep track of your daily goal progress from the end screen. Depending on how you played, you have the option to select Play again, Practice, Perfect it or Continue.
If you liked the song, add it as your favorite. Select more options to see if other versions of the song are available. When a song includes chords, you can check the chord diagrams for guitar and ukulele from more options as well.
