When you're ready to give singing the Star Spangled Banner a try this little solfege tool can help you learn it faster.
When learning any song the more deeply you understand it the better. Songs have layers. Consider the Lyrics as one layer, the Rhythm another layer, Harmony another layer and its Melody another layer.
Solfege helps to focus on one specific layer, the Melody and how the notes relate to the Tonic.
Tip of the Day: Find on the piano the "second to lowest note" you can sing. Say it's name out loud. Try singing the song now in the key you said out loud. Remember: Your note starts on sol.
