Click the green flag to start. Press the "a" key for the alto line. Press the "t" key for the tenor line. Press both simultaneously for harmony—or asynchronously to experiment with rounds.
NOTES With the recent 4th of July holiday, the U.S. national anthem was on my mind. I came across this series of performances of the national anthem in a hotel lobby — for example, https://www.youtube.com/watch?v=y49Omj1onuI — and was just SO inspired by the stateliness and harmonization that I wanted to play with harmony in today's project! Obviously, if I had more time, I'd love to finish the entire song and all four parts! My approach to the progress indicator sprites is incredibly hacky and imprecise. :) So I'd want to improve that... CREDITS I found the score at https://www.musicnotes.com/sheetmusic/mtd.asp?ppn=MN0042739
