I learned something interesting recently. Did you know that the PTG tuning exam allows the use of a Sanderson Beat Rater? This was discussed this past week and it was revealed that the rules do not forbid it, because only visual tuning aids are not allowed.
What do folks think about that? The PTG website states that:
Candidates who use electronic tuning devices in their work must nevertheless demonstrate their ability to tune by ear, unaided by electronics.
If you are wondering what a Beat Rater is read below:
If you are trying to teach or learn beat rates, have we got the instrument for you!
The new Sanderson Beat-Rater gives you the beat rates for all the major thirds in the temperament region, from B2-D#3 up to D#4-G4.
Similar to the Accu-Fork in design, the Beat-Rater produces clicks at the tempo of the appropriate beat rate. Set for F-A; it produces 6.93 clicks per second, for example.
The four pushbuttons set the beats of four contiguous major thirds, so it is easy to learn the sound of beats in the ration of 4 to 5 as used in the contiguous thirds test.
Best of all, all the beat rates can be slowed down or sped up together to fit the beats of a particular piano being tuned, which will rarely have theoretically correct beat rates.
