Piano key frequencies. This is a list of the fundamental frequencies in hertz (cycles per second) of the keys of a modern 88-key standard or 108-key extended piano in twelve-tone equal temperament, with the 49th key, the fifth A (called A 4 ), tuned to 440 Hz (referred to as A440 ). [1] [2] Every octave is made of twelve steps called semitones.
May 6, 2014 · The figure in the Wikipedia article tells you what you are asking, if you're willing to tabulate the deviations by reading the green line.. The vertical axis is the number of cents that the key is tuned away from equal temperament, e.g. the C two octaves above A440 (C7) is about 10 cents sharp, i.e. the frequency is a factor of 2 10/1200 sharp, or the actual freuquency is

Fiction: Ancient instruments such as Tibetan bowls, Pythagoras monochord, ancient flutes, have been found to use 432 Hz as their base pitch. Fact: Hertz is a modern term coined in 1930. Before that it was referred as “Cycles Per Second”. The first time “Cycles Per Second” could be accurately measured was in 1834, when two instruments were invented:...
Fiction: Pythagoras’ A was 432 Hz. Fact: Pythagoras’ tuning system is ratio based. It is not based on an absolute pitch, but rather on the relations from an arbitrary reference pitch. We already know Pythagoras could not have known what a second is, so he could not know what Hz meant. Indeed 432 is a multiplication of the ratio between C and A, whe...
Fiction: Mozart used 432 Hz for all of his music. Fact: The only evidence for Mozart’s A comes from an ancient tuning fork from 1780 with the tone of A=421.6 Hz. This tuning fork belonged to the Viennese piano builder Johann Andreas Stein, the leading piano maker in Vienna at the time, who was responsible for Mozart's pianos as well as Haydn’s and ...
Fiction: Verdi has used 432 Hz for all his music. Fact: Verdi used several tunings across his life. As an opera composer he was aware of the pitch inflation (pitch standards rapidly rising to achieve a brighter orchestral sound) that was happening in his time, and was concerned it was putting a strain on singers voices as they struggle to hit the h...
Fiction: 432 Hz is the way everybody used to tune in the past, but we have now forgotten the ancient wisdom of our ancestors. Fact: Musicologist Alexander John Ellis has searched, measured and documented ancient pipe organs and tuning forks. Here is a graph representing his most important findings—as you can see the only mention of 432 Hz was propo...
Fiction: 432 Hz is the frequency of the heart / brain / earth / sun / water Fact: The frequency of the heart fluctuates between approximately 1 Hz to 2.5Hz. It does not have a steady frequency that can be multiplied to achieve 432 Hz. Brainwaves or Neural Oscillations range between approximately 1 Hz and 70 Hz and are not tuned to 8 Hz or other div...
Fiction: Goebbels and the Nazis tried to take over the world with A440Hz. Fact: In fact, it was the British Standards Institute who arranged an international conference in London 1939 where it was internationally agreed for A=440Hz to be the standard.

Fiction: Cymatics—the unexplored scientific realm, provides images as proof for 432 Hz being the frequency of water/universe. Fact: There have been several videos and images out there presenting beautiful cymatic imagery as proof for the 432 Hz theory. However these images are produced by resonant bodies (water or metal plates) which can be tuned t...
Fiction: Your music will sound better at A=432Hz Fact: Musical aesthetics is a flexible thing. Musicians are not obligated to use 440 Hz as their base frequencies, and many orchestras around the world use different pitches according to the music they are about to play. It is generally agreed that baroque music is to be played at around A 415Hz, cla...
432 Hz seems to be just another number without any special significance over others. Tuning your music to a specific frequency will not unlock cosmic powers, or make your music sound better or worse. Having said that, there is no rule or law that requires musicians to stick to the standard tuning of A=440Hz. Serious musicians should all use alterna...
On a violin (or viola or any fretless stringed instrument) this is possible, and we can play a beautiful, perfect E at `440 × 1.5 = 660\ "Hz"`. But notice (from the frequency table above) that a piano playing the same note will play E `= 659.26\ "Hz"` [just a little flat!].
frequency a semitone up from A4 (A♯4), multiply 440 by the twelfth root of two. To go from A4 to B4 (up a whole tone, or two semitones), multiply 440 twice by the twelfth root of two. For other tuning schemes refer to musical tuning. This list of frequencies is for a theoretically ideal piano. On an actual piano the ratio between semitones is ...

May 8, 2021 · We generally call frequencies down in the 20-200 Hz range ‘bass frequencies’, those up in around the 4,000-20,000 Hz range ‘treble frequencies’ and those in between (200-4,000 Hz) ‘midrange frequencies’. The diagram below shows a frequency spectrum of a musical piece and some indication of which instruments generate their most ...

At the top end of the piano, moving over one key increases the frequency by over 200 Hz. What remains the same is the percent increase– as you move one key to the right, the new frequency is about 6 percent higher than the previous note. Put another way, the frequency ratio between one piano key and the next is about 1.06.
