Wow—I had no idea how talented Chewbaca mom was! It is refreshing to hear the Star Spangled Banner sung without changing keys. She started on a pitch that she can handle, then move up to the higher section with ease. I noticed in this video of her singing the Star Spangled Banner, how great her placement is. She “scrunches” her nose especially on the higher notes, which gives her power and makes her match the higher pitches with her lovely lower chest voice. I teach this technique in my vocal series which you can buy at http://relaxedsinging.com/ Way to go, Chewbacca mom! Keep up the good work! For further information about Chewbaca mom, here is a recent article about her.
