PERFECT MUSICAL INSTRUMENTS
Sir,-While listening to a Music at Your Fireside session I heard the compére announce that a piano could not be regarded as a musical instrument because G sharp and A flat were played on the same note and could not be separated. In a ’cello, viola, violin and slide trombone, he said, this could be done. Therefore they were the only perfect musical instruments. The reason given was that there was one-sixth of a tone difference between the two notes. This corresponds to a frequency difference of 7 cycles (taking the frequency of G, 384 cycles, and A 426.67 cycles per sec.) Could this slight difference of frequency be distinguished by the human ear? And could this "note be played to this accuracy on any of above-mentioned instruments? Could these instruments be tuned to this degree of accuracy? —
