2018年1月14日 · The "standard" pitch today that most musicians tune to is the A above middle C, which equals 440 Hz; all the other notes are pitched in relation to this note. In earlier times and cultures, this note had other values—as low as 376 Hz in early eighteenth-centrury France, and as high as 560 Hz in early seventeenth-century Germany (referred to ...

2020年3月8日 · The fact that Verdi used 432 Hz (if that is in fact true; this is the first I've heard of it) has very little bearing on the tuning of a piano unless it is a piano of Verdi's time. It might also be of interest for singers of Verdi's music. The fact that 432 is differently resonant with 8 Hz than is 440 Hz is not relevant in the least.

2021年4月22日 · A Neuropsychology Study on Music and Emotions: Frekansların Sihri – 432 Hz 440 Hz’e karşı: Ayrı Frekanslara göre akortlanmış neşeli Ve hüzünlü müzikler Insan Psikofizyolojisi üzerinde Farklı Etkiler yaratır mı? Müzik Ve Duygular üzerine Bir nöropsikoloji araştırması”. Journal of Human Sciences 18 (1):12-33.

2015年12月29日 · @cjm Note that electronic tonewheel organs can be re-pitched by adjusting the tonewheel rotation speed, but all that can do is adjust the whole instrument from A=440 Hz to A=442 Hz, for example. Tuning between different notes would probably require replacement of individual tonewheels.

In a mathematically ideal string, the harmonics are perfect multiples, but in real strings, the harmonics are a little sharp. So a piano's A=440 note will not have a harmonic that is exactly 4 x 440 = 1760 Hz. This means that pianos are rarely "in concert pitch" all across the keyboard, and any piano which is will sound worse for it.

2020年11月7日 · Playing 440 Hz, what are the approximate harmonics for a trumpet? For a flute? This to help students understand the differences when those instruments play the same note. I've been to many website, including University of New South Wales. I …

2017年3月8日 · Some people with perfect pitch may be irritated by music not at A=440 Hz. They're going to be irritated a lot when hearing modern recorded commercial music, and some not-so-modern stuff too! Others can recognise a variance from A=440 Hz, but they aren't obsessed with it. Like looking at a photo or movie with a slight colour cast.

2014年6月4日 · Various national and international standards define the frequency of this note. For example, ISO 16 specifies that musical instruments should be tuned such that A4 is 440 Hz. Other standards specify A4 as 415 Hz, 435 Hz, and various other values.

2015年11月29日 · If you can cause the tympanic membrane of a normal-hearing human to vibrate 440 times per second, they will "hear" the pitch we call A4. So, there are two ways to go with your question. A device that is designed to produce 440 Hz here on Earth is designed to cause normal earth air at normal air pressure to vibrate 440 times per second.

2014年12月24日 · Given your example, the distance in cents between 440 Hz and 450 Hz: c = 1200 × log 2 (440/450) c = –38.9. so 440 Hz is about 39 cents below 450 Hz. For more information, see the mathematics of musical scales. There’s also some information about the logarithmic scale in the linked entry for musical cents.
