I've added yet 3 new obscure quizzes to my List of Nomenclatured Intervals, and I'm doing good at all of them!
I've ditched easy mode and the quiz in which you were asked to guess whether a played interval is limit 13 or less, or a prime limit over 13, because I wasn't doing great at them at all, scoring often below even what luck can bring as a score.
Now the first test showed in the video is about checking every single primes you think are factors of intervals you hear. No maximum of choices but you lose grades for factors you check and that are not part of the ratio of the interval presented. I'm pretty wild at that one, maintaining a score of 60% good answers over 5 minutes.
The 2nd test starts with you picking a prime in between 3,5,7,11,13,17,19 or 23, then you're presented 10 intervals and have to tell whether your pick is A-The Prime Limit of intervals you hear B- Another factor encompassed by the ratio of the interval heard but not its prime limit or C- Not a prime factor present in the ratios of intervals heard.
Third quiz showcase intervals that count 3 prime factors. You are presented 4 choices : the 3 good ones and a bogus one not part of the factors of the ratio of interval heard. You pick 2 choices among the 4 and try guessing which character is missing from the general facture of interval heard. I score friggin 70% good first pick out of 10 questions at this one! Remarkable!
Then the final test is the one you might have seen in my other posts about bragging my ability to discern which prime factors make up harmonies I hear.
