This reminds me of an old video game sometime in about 1996, it may have been Myst, where to level up the last puzzle on the current level was a screen with slide bars where the game played a 12 note musical passage and you have to move those slide bars to play the passage back. And I think you got 5 tries until the sequence changed. I was out and about and my roommate was playing the game on his computer. When I got home he asked if I could help him, that he had been stuck for 3 hours on this puzzle. He explained to me what had to be done, and I said "Okay. Play me the notes." He said "I am on the 4th try here so let me mess it up once more so you get a fresh puzzle." I said "Nah. Just play the notes." He played the notes, I made a sketch on paper as I listened, and in under 2 minutes he was on to the next level. I would imagine tone invaders might be something similar? Where you kill the invaders by tone matching?

I am using the new 1040XTRAEZ form this year. It has just 2 lines.
