In question 3, I might word it "When the first note and the fifth note OF A SCALE are played as a chord at the same time." Also, I typed "Perfect 5th" as my answer on my first attempt at this quiz, and it wound up being the only answer I didn't get because I didn't type out "fifth." In question 7, as soon as I typed the "F" in "Fermata," it instead functioned as an answer to question 26, because "f" is the abbreviation for "forte."
