Concert Pitch in Chopin's time -Diapason nei tempi di Chopin

Come vedete dal testo di Montal (1836) il diapason nel 1829 andava da 434 a 438 Hz, mentre nel 1836 andava da 437 a 441 Hz

As noted above in a period book on tuning by Montal, concert pitch was between 434 and 438 Hz in 1829 and by 1836 it was between 437 and 441..
