Jumping back in ...

The 5th beats at 3:2 and this is the interval that must be "clean". It also has a beat at the 4:6 which is more prominent on some pianos than others. Tuning at the 4:6 will make the 5th too wide due to the increased inharmonicity of the higher partials.

It's easy for "newbies" to be confused by the 4:6 beat and place the upper note too sharp (or lower note too flat). This is another good reason for not trying to use the 5th as a primary tuning interval, n'est pas?

AF,
Considering the spread of a fifth, it would seem to me that there would be opportunity for higher partials to be all over the place with the inharmonicity differences in wire. I.e., a plain wire and wound wire. By my ears, the beats of the higher partials are no where near double sometimes, but I haven't really got into it yet. I still don't see how you use that beat speed to put the wire being tuned into your tuning pattern. More info, please.

The beats are twice the speed so you can make a much more accurate judgment as to the correctness of your interval.

AF,
And just exactly what would you discern from hearing the second, or higher coincident partials? How would you make use of the information at that point?

Just curious.

>From Alan Barnyard's post: "5ths have such a slow beat that they are hard for most to tune accurately, as a primary interval"

It's much easier to use 5ths by listening to the second intersection of partials and not the first. However you will have to sensitize your hearing to discern that point.
