Where do you found pure intervals in a piano ? hidden under the keys ?
No such thing for me, sorry

No such thing for me, sorry I once found one behind the trap-work in a Lester spinet. Gosh that was a pretty thing!

Is that a laptop computer on the struts?
I highly recommend against placing an electronic, HEAT generating, FAN cooled device near the strings you are trying to tune, or just tuned. It will change the pitch of the previously tuned strings by several cents, at a minimum.
If you must use a laptop, put it somewhere else, away from the piano.

No such thing for me, sorry The challenge for beginners is in just understanding the relationships. But, yes, we do find pure intervals, while tuning. Example: F3A3 = F3D4 What now? Well, which direction do you change the top note of a pure interval if you want it to beat wide? A) Raise it B) Lower it You see? The exercise is very powerful for beginners. Also, many tuners tune pure 12ths.

Thanks Prout. The laptop is usually on two ice paces, which are on a towel, which is on a piece of plywood. But in this case, pedagogy trumps tuning stability. (Anyway, that piano hasn't been tuned in years. It's just for teaching tuning on. It's constantly being tuned and untuned.

I once thought I found a pure interval under the piano, but it was just a cat pure-ing ;-)

I first thought it is too trivial: everyone knows that a wide interval gets even wider if you raise the upper or lower the bottom note and that a narrow interval gets worse when you raise the bottom or lower the top note and everything follows from that. But then I realized that you need not only know that but you should know it instantaneously without thinking if you want to tune pianos efficiently, and I noticed my response times could be improved upon. So I think it's an excellent quiz! 8. You lowered the top note and a fast beating wide interval beats faster. A. The interval was wide. B. The top note became sharp. C. This question is meaningless I think the correct answer is D: you lowered the top so much that the interval is now narrower than it was wide. Maybe you meant "flat" in B. This is probably a very important question: I think everyone has at some time narrowed a too fast beating P4 with it beating slower but narrow instead of wide. 44. You change the bottom note and a fast beating narrow interval beats faster. Was the interval originally wide or narrow? A. Wide B. Narrow C. I don't know You say the interval was narrow and then you ask if it's narrow or wide. Makes no sense. 47. A fast beating wide interval speeds up. A. You raised the top note. B. You lowered the top note. C. This question is meaningless Both A and B are correct. Kees

Hi Kees,
Thanks for the comments.
Here are my responses.
8. I added your answer as the correct one. (I wrote it so the question was meaningless, but I like your answer. It too makes the student think.)
44. Changed to "You change the bottom note and a narrow interval beats faster. Did you raise or lower the bottom note?" Choices: Raise/Lower/Don't know.
47. I added D) Both A and B.

[47. A fast beating wide interval speeds up. A. You raised the top note. B. You lowered the top note. C. This question is meaningless
Both A and B are correct.
Kees Kees, can you explain how could this be assuming that the interval is still wide? (because the question says so)

Allow me.
You can read that the question could imply "A fast beating wide interval speeds up (after slowing down first, passing pure, and then speeding up to end up faster than it started.)"
I assume that's what you were thinking, Kees.
Technical writing is not easy. Thank you to everyone who is trying to help me clarify.

That would be a far-fetched interpretation for a wide interval. Moving pin the more than 25 cents? Just make the quiz 25 questions in 10 minutes, get rid of the ambiguous questions and you are fine.

True. Kees was the one who mentioned this possibility, and you and he are absolutely right; the questions like that are ambiguous. I will prefer to rewrite the questions to eliminate or reduce the ambiguity.
The quiz is for my students. They need the practice. In my opinion, 50 is not enough ;-)
If you have suggestions as to how to reduce or eliminate any ambiguity, I'm all ears.

If you have suggestions as to how to reduce or eliminate any ambiguity, I'm all ears. Hakki, a "fast beating" interval could be taken to mean for example a P4 that beats at 2 bps instead of 1. I agree more is better, the goal is speed. I've written many exams and quizzes when I was teaching and I would always run them first by a teaching assistant: they would always find ambiguities. And sometimes at marking time more ambiguities would show up. So I recommend having someone check your quizzes. But you already figured that out obviously... Kees
