Tuning Source Book/Test: hints #2 & #18

[David Ilvedson]

I wouldn't change your temperment for the test unless it is lacking...another mentor/technician should be able to tell you how it is...

Don't forget that you have a 1 cent lee way in the temperment area.   Tune your temperment...by the way how does it proceed?...then listen to your contiguous thirds to see if you are in the ballpark.   Do your temperment fast beating intervals progress evenly?  Do your 4ths beat around 1 beat a second?  Do your 5ths beat less than that?   If so, it will pass the temperment part of the test...



One other thing...don't have your A3-A4 octave too stretched for the test...keep it just wide of pure...A3 slightly flat

Subject: Tuning Source Book/Test: hints #2 & #18





 

Greetings,





        In hint #2 it claims that you dont want to tune a piano with it muted to single string for the first time in an exam room. What is so unnerving/bad about that, aside from just not being used to it? 



        In hint #18 it says that you should learn to hear 4:5 ratios on contiguous M3's by counting 1 2 3 4 and compare to 1 2 3 4 5.  How does one go about hearing beat rates while doing/counting this? Is the Source Book implying that the contiguous M3 from A2 to C#3 is 4BPS and the next M3 from C#3 to F3 is 5BPS?  If the beat rate in higher pairs of M3's are more than 4 or 5 BPS, say 6 or more than do you have to do the math to arrive what the contiguous M3 above it should beat like?



  Also, has a tuner ever passed this exam without the skill of knowing how to handle/count the 4:5 ratio? Not that I am not willing to learn it but, that will take time and I have concentrated since inception of tuning on 5ths, 4ths, 3rds, 6ths, octaves and other tests.



thanks in advance,

Julia
