The famous Stradivarius violins are said to have been build to be in tune to A=432 Hz. A piano normally could be lowered, once, from 440 to 432 but not the reverse and I wouldnвЂ™t want to be the tuner trying to bring it back to 440. The guitar can be tuned down, no problem, but itвЂ™s annoying. Later, he indicated that A4=432Hz might be slightly better for orchestras. Instruments hard tuned to 432 are likely a hundred years old, or made is a few countries in Europe. In 1874 he wrote his Requiem using the official national French standard of A4=435Hz also called the 'Diapason Normal'. In the 19th century Italian composer Giuseppe Verdi tried to stop the increase in pitch to which orchestras were tuned, he suggested the use of A5=864Hz (thus A4=432Hz), a concert pitch subsequently named 'the Verdi Pitch' after Verdi himself. so this is nothing ideological about 432Hz vs 440Hz, its about quality representation of music theory, sound science and history. The French used several frequencies which were frequently inflated, from 404 Hz in 1680 up to 435 Hz in 1859, with 430 Hz being the classical pitch and 435 Hz the diapason normal pitch. In the Baroque Era some of the pitches used were A-415 pitch, but levels as high as A-465 (17th century Venice) and as low as A-392 (18th century France) are known to have existed. Tonal music tends to lower in pitch, and the effect may be quite more important than the difference between 440 and 432 Hz (32 cents, only about 1.5 comma). As such in an unamplified setting, a higher pitch sounded sharper and louder. This is an international standard and the further tuning of each instrument is adjusted based on the concert pitch. The main reason for this is quite simple, an orchestra cannot play louder, so the only way to increase the apparent loudness was to increase the pitch. Music based on 432Hz transmits beneficial healing energy, because it is a pure tone of. Audiophiles have also stated that A432 Hz music seems to be non-local and can fill an entire room, whereas A440 Hz can be perceived as directional or linear in sound propagation. However, generally the tuning frequency rose gradually over the years. Music tuned in A440 Hz offered a more outward and mental experience, and was felt at the side of the head and then projected outwards. In the past the tuning frequency was typically lower than the current standard and also region specific. But since this constantly comes back and it leads to a lot of misconceptions about the whole 440 Hz vs 432 Hz thing.
