What is The perfect pitch? You are likely already knowing that perfect pitch, also called absolute pitch, is the ability to key out or play a note without utilizing a reference.
The ability lets a musician execute several skills, also tuning a musical instrument, singing whatever tone at wishes, or transcribing really quickly and in the accurate key.
Though this ability is rather uncommon (around one in ten thousand), several musicians who have it are skillful at both identifying and also recreating notes and making their guitar lessons easier.
Theory of The Perfect Pitch.
The answer to this question isn’t a matter of “what?” but more a question of “how?”.
How can it be that a minor proportion of folks is able to detect a so-called elusive “quality” from each note, which most of us can’t?
How does perfect pitch really work,
what are these qualities? Some musicians do really well without the ability and, simultaneously, we all show impressive hearing abilities, such as the ability to distinguish familiar voices from a crowd.
Then, why can we not hear the tone qualities between different notes?
To answer those questions, we have to know some primary acoustic precepts.
To begin with, toned sounds by any source contain basic frequencies from the notes being played as well as harmonics of those frequencies.
Harmonics are also called overtones and each tonal sound has them. Even the plainest acoustic wave will render harmonics. This is because of the physical nature of waves to produce other waves.
Harmonics from a tone are multiples from the basic frequency.
When you play an A440 on your musical instrument, the sound you hear is created from 440 Hertz, 880 Hz, 1320 Hertz, 1760 Hertz, 2200 Hertz, and so on.
Energy from the basic (440 Hertz) is frequently the sharpest and energy from all raising harmonic decrements, for a common ruler, just not on every musical instrument.
The “1st overtone” is the same as the 2nd harmonic.. This may get confusing therefore I’m keeping with the terminology of harmonics.
Various musical instruments contain various harmonic stages (“spectra”).
For instance, a clarinet sustains a heavy fundamental with stronger strange harmonics than even ones.
Analyzing the spectrum of a particular guitar, however, reveals that its sixth and seventh harmonics are louder than the third, fourth, and fifth.
Naturally, the spectra of different musical instruments differ.
Otherwise, the musical instrument would sound the same. The harmonic spectrum from a tonal sound is what gives it its own timbre, in addition to noise elements.
We can easily tell a difference between a flute and a saxophone since they’ve really dissimilar harmonic spectra.
The harmonic levels carried in a tonal sound apply it its unusual “quality” or timbre.
Going back to the subject of perfect pitch, we already understand that those with perfect pitch distinguish the notes through their own “quality” or timbre.
We understand that composers with perfect pitch might select a certain key for its characteristics, depending upon the mood of the piece.
But how does this connect to harmonic spectra and quality, since we understand this depends on the instrument?
All right, the shocking, but obvious truth is that there’s no physical difference in “quality” between the different notes.
Whilst a matter of fact, if there were, we’d have measured it many years ago and there would be no mystery about perfect pitch.
The deviations between notes are only perceived by folks, because of peculiar resonances and frequency reception by the human ear.
The ear is like a microphone, with moving sections, which vibrate at certain frequencies and are better at picking up more frequencies than others.
The ear will react differently to the different harmonic parts of any tonal sound.
The outcome is that we perceive some frequencies as a good deal louder than others while, in reality, they’ve equivalent physical loudness.
The reaction of the ear is seen with an Equal Loudness curve and is the same for everybody with fine hearing.
The ear is most sensible at 4000 Hertz and a sound at thirty Hertz has to be about 1 million times as powerful as a single at 4 kilohertz to be sensed the same.
The ear has got resonances because of certain resonating parts. There’s a resonance at around 3000 Hertz due to the auditory canal.
Additional sources for non-linearity in the ear are the complicated cochlea behavior, the vibe of the eardrum, and the bones in the middle ear.
Naturally, the equivalent volume response of the ear is just a piece of the story of human hearing.
There are several different phenomena carrying on when the ear is submitted to multiple frequencies, which is almost all the time.
For instance, as 1 frequency masks some other and how this depends greatly upon the values of those frequencies. can
Then What is The Perfect Pitch?
In summary, the perceived difference in harmonic spectra between notes from a scale is at the root of perfect pitch.
First of all, there exist factual harmonic levels of sound. And then there’s a perceived spectrum resultant from the response of the ear.
People who have the perfect pitch are able to pick up the harmonic vibrancies arriving from the frequency response of the ear.
The main reason that perfect pitch is so uncommon is that we tend to fixate on the fundamental pitch of notes and, as instrumentalists, harmonics are not considered with such importance.
Learning the ability to perfect pitch is about learning to listen to the harmonics of tonal sounds, which is for sure possible.
Keep it up.

The perfect pitch is difficult to find, I have meet people that just got it without practice, while we other normal humans has to practice the guitar to find the pitch, but once you have it, learning new songs just from listening is much easier.
Do I understand it right, so the pitch is when I can hear from say a song on a cd what chord they are playing etc.?
Yes that’s right, some have to sit and listen for a while and others can just hear it right away, but practice to hear pitch/chords/notes makes better.
In my school days long ago my music teacher used a tuning fork to give us perfect pitch for our songs . The electronic gear today does the same I guess but the human ear is the real test.
I can pick a slightly flat note most of the time ( seldom high) just by ear – I think some people are born with a sense of pitch while others will never have it an need electronic readouts to do the job for them
