HOW TO USE THE GRAPHS AND AUDIO TO IMPROVE YOUR EAR
1. Listen to the recordings while looking at the graphs.
2. Listen to the filtered recordings and try to confirm aurally that the beat speeds are following what the graph says.
This improves your "Beat Speed Difference Sensitivity" - Your ability to hear small differences in beat speeds.
3. Listen to the unfiltered recordings and try to hear the specific beating partial within the unfiltered recording.
This improves your "Tuner's Ear" - Your ability to filter frequencies at will.
GRADING OF THE TEMPERAMENT
INSIGHTS
You must understand interval sizes in the following courses:
Equal Temperament, and Wide, Narrow, and Pure Intervals,
in order to follow the logic explained below.
IMPORTANT
This is a traditional refinement procedure.
It requires you to finish the temperament before you can have any insight.
It also requires you to test multiple intervals before you get any valuable information.
The Go A.P.E. Sequence allows to to self correct before you are finished.
Also, because of the incredible accuracy in the Go A.P.E method, you fix notes the way they were tuned. (No searching high and low for reasons why a note is wrong)
Analysis
There were no intervals that were obviously out. However, if we look at the numbers, we can say a few things.
The methods I use below to check the logic are from the Go A.P.E. System.
Are F3 and F4 both too high?
This could produce a good F3F4 octave, but the Skeleton would have been shifted. Upon relistening, the Lower Skeleton changes seem a bit large, and the Upper Skeleton sounds like it could have a high F4 (A3C#4-C#4F4-F4A4 sounds more slow-fast-fast instead of slow-medium-fast)
The Skeleton (F3A3-A3C#4-C#4F4-F4A4) Not S-M-F-Faster
I should have been able to hear that.
Could the A#3 be too high?
Yes. If we listen to the way it was tuned, I should have been able to hear that as well.
How A#3 is set. (C#4F4-A#3C#4-F4A4) A#3C#4 seems too fast
How A#3 is checked. (F3A3-F#3A#3-F3D4) F#3A#3 seems too fast
Is the B3 too high?
When listening to the Whole Tone M3 Ladder (part of the Go A.P.E. sequence) we can hear G3B3 on the fast side and B3D#4 on the slow side.
How B3 is tuned and checked.
(F3A3-G3B3-A3C#4-B3D#4-C#4F4)
G3B3 (2nd) seems fast, B3D#4 (4th) seems slow
Conclusions
Using the feedback model I have developed for improving aural results,
I was able to find areas where this tuning could be improved, and confirm by ear using the system that tuned these notes originally.
Even though this tuning scores high, I should be able to improve it with the Go A.P.E. Sequence.
Traditional Refinement Procedure (Obsolete)
In refining a temperament, we identify two or more problems that suggest the same note may be too high or too low, and then change that note to fix multiple problems.
This reiterative method helps us improve the temperament bit by bit.
This is why it is imperative that, if you want to improve your aural tuning, you must improve your beat speed recognition.
Exercises like these can help greatly.
You are encouraged to read the analysis and confirm aurally that you can hear the findings, and understand how the improvements suggested would improve the beat speed progressions.
In this way, you will improve your ability to rationalize the logic, and improve your ear to be able to hear smaller and smaller beat speed differences.
Improving these skills will greatly improve your temperament.
Keep up the good work and don't give up! You're getting better all the time!
