[CAUT] Origin of P12ths StopperStimmung/tuning

[Kent Swafford]

Bernhard,

I am very pleased you decided to post.

I have tuned 4 pianos today with Tunic OnlyPure. I am very happy to be  
able to tune pianos by this method because of the very fine sound that  
results.

Although I might still prefer to know a little more of the technical  
knowhow behind these tunings, I wouldn't choose to be without the  
tunings just because I don't know the technical details.

All the best,

Kent


PS -- For readers who may not know, a "duodecime" is a twelfth.
