Your question is sort of a strange one. It's somewhat like saying "I have an unusual amount of students that are amazing at playing fast; how can I make them play even faster?"
As a teacher, I always try to work on my students' weakest points, while also recognizing their strengths. Personally, if I have a student with great pitch recognition, then that's probably the last thing I'll work on with them.
(it's also probably worth asking if your students actually have perfect pitch, or merely relative pitch as Elise already noted).
That said, happy your students have such skills.
IMHO, this skill is not "real" in the sense that perfect pitch is relative to the instrument and scales within a piece. One *could* have perfect pitch related to piano, but that is useless to a violinist.
When I was young I was told I had perfect pitch, but honestly it's just "relative"-not as in being out of tune being relative, but relative to the scale. That is why someone who supposedly has "perfect pitch" and plays out of tune in the 1st section of an orchestra, either does not really have a good ear at all, or does not practice his/her violin. Playing scales in perfect tune-save for the double stop exceptions where relative is ok-is a much better skill than "perfect pitch" will ever be.
In short, yes I can sing 440, but mostly anyone (or at least, most of us violinists) can do that. I am not special. What is important is I practice so I can play pieces in tune at 440, 443, 445, etc., relative to the passage being performed.
Interestingly, in my son't precollege program, something like 75-80% of the kids have perfect pitch. This isn't an anomaly -- it is true of many, if not most, kids who started music lessons early, practiced a lot daily, and are studying at higher levels. It's also more common in children who learn tonal (verbal) languages where pitch inflection is especially important. A lot of Asian languages fall into this category.
Some of these kids (like my son) have extreme perfect pitch -- he can hear the pitch of everything in the environment around him, to the point where it took him several childhood years to learn to "cope" with all the pitches in his environment. Others, like my daughter, are less extreme. She can identify pitches by ear, but often needs to sing them out loud first.
In my experience, you don't need to do anything beyond exposing young kids to pitch and labeling it for them to develop perfect pitch. They either will or they won't. If they do, you can encourage them to keep practicing it, because like any "muscle," it can be strengthened or weakened with use.
But what you DO need to do as they become tweens and teens is teach them about theory and relative pitch. At age 10, an F# was an actual single entity for my kids. Now, they understand there are a range of F#s depending on context. In other words, they need to be taught relative pitch, and they need to be taught the theory behind it. (This is less important for pianists for obvious reasons.) To do this, we started with scales and worked on it melodically. Then arpeggios, especially the diminished and dominant), as well as starting to work on it harmonically. They have learned the written theory along with it as well.
There are some books that some students might find helpful, like Cellomind or Violinmind. While they aren't necessarily designed for perfect pitch kids, they are great at teaching intonation in both horizonal (melodic) and vertical (harmonic) situations.
My thought on Perfect Pitch, is that, as a child, once I thought I didn't have it, I wanted so much to train it in myself, that I drove my parents crazy listening to an A2 on the piano for so long, I eventually found I had it. I chose that note because of the higher overtones, that would be closer to my violin strings.
My view: training can do what you thought was impossible.
What I would call "Acquired Absolute Pitch" seems more like the precise memory of a particular timbre: my own violin A at 440Hz, vs the same violin A at 445Hz as I switched regularly from playing with classical piano to Argentine bandoneon.
A colleague with True Absolute Pitch insisted that this form was independent of timbre.
It’s not very easy to develop this thing I think. There are pros and cons to having perfect pitch or not having it. Usually if you have played an instrument before age of 10 it is possible to have it but I don’t think it’s something that can be simply developed. It just occurs in some people really. Like Brett from TWOSET tried to get perfect pitch but in the end it never really worked.

Of course a teacher could cover what is covered in the course but I find that taking charge of most of my aural learning needs in my own time frees up time in my violin lessons for other technical aspects
First off, you memorize pieces much quicker, and you don't need to look at the score.
Second, and the biggest one is intonation. Intonation for perfect pitch people is like this: 1. you imagine the note 2. train your fingers to go to the correct place, aligning with your mental image until you can do it automatically 3. profit
If you don't have absolute pitch, you've already failed at step one because you can't imagine the note, otherwise you already have perfect pitch. I'm guessing people with no perfect pitch just feel where they are and guess, hoping that they land on the correct spot? If you don't get it close enough the first time you're screwed because now you don't know if the note was too high or too low and you're now lost because you can't hear the special ring you get when you are in tune because you've accidentally overshot or undershot your shift.
Third, you get what is going on in pieces without having to study the score because you can hear what key you're in and instantly figure out how the piece is progressing theorywise with some basic music theory.
It's no wonder why virtually every accomplished violin soloist has absolute pitch without exception, perfect pitch alone is easily worth around 3-5 years of violin training (imo). I think it's one of those things where people who can see don't realize how good it is to have eyes, people who have ears don't know how good it is to be able to hear, and healthy people forget the benefits of not being ill...
One thing I am curious about is, for people without absolute pitch, what happens if you mess up a shift and now you don't know what note you are now on? You know you went too far, but you don't know if you're in G6 or G#6 territory, how do you reorient yourself without a reference?
I've only known one really "perfect pitcher." He was Stan Ricker, who played in our orchestra for years. He had been a "Tone Master" recording engineer, widely regarded (google him!). He conducted our orchestra one season and he was able to do one thing I never saw before; he was able to "tune" 4 of our wind players simultaneously, while they were playing. He could tell you not only the pitch of any note but also the frequency of A for that pitch of the note. He could tell the speed of a vehicle by the pitch of the tires on the road, and could identify WW-II propeller airplanes by the pitch of their engines.
That's "absolute perfect pitch."
This assumption is misguided. I know many musicians with perfect pitch who have a really difficult time coping with the reality of live performance where pitch is relative, and the interval is central. And don't get me started on the numbers of them that go bonkers when having to deal with transposing instruments, historical pitch centers, and different temperaments. There are skills related to being able to generate specific pitches, as well as matching pitch and playing specific qualities of intervals that are the most important variables for musicians.
Having so-called perfect pitch is not going to compensate for not being able to count, producing poor tone quality, or having the personality of a cheese grater. That's why not every single violinist has perfect pitch, and there are many of us with lengthy, successful, and engaging careers who were not born with perfect pitch, but have put in the time and effort to develop a functional equivalent.
I just saw a superb presentation by the Apreggione Ensemble in Boston where they performed on numerous keyboard and string instruments of different historical temperaments. To paraphrase, the existence of numerous pitch systems beyond equal temperament is a wonderful diversity in music, and those that would want to erase the existence of such things because of their insistence on perfect pitch of equal temperament are missing the forest for the trees.
I had to play in a quartet one time with someone who insisted that notes didn't move around, they had perfect pitch, and the note was the note. They didn't care about the function of the note within the greater harmonic context, and they were impossible to play with because they refused to make chords work, to the point they expected the entire ensemble to adjust everything around their note, even when they were not playing the tonic! Frustrating beyond words, and I refused to play with them ever again.
Practically every claim in this post is ridiculous. And, your analogy to a blind athlete is a bit of offensive sophistry.
There are many skills that a violinist needs--intellectual, emotional, and physical, not to mention a work ethic.
The inability to trill, vibrate beautifully, play with a stead tempo, achieve a high level of spicatto,
play at the exact required contact point, focus for long periods of time, not get nervous, think through problems, play with elegance and grace, understand style and articulation, use muscles efficiently--any of these can cut short a career. There are so many other requirements as well.
The idea that having perfect pitch is up on the list somewhere is frankly ridiculous. If anyone feels that the huge effort to memorize the sound of each pitch is somehow desirable, then go for it.
I think, however, you'd be much better off using that time to practice with a metronome, read a good book on music, record and analyze your playing, or simply practice more in general.
That said, I think this discussion has really gotten into the weeds, because OP was asking about training the ears of students who already seem to have some sense of absolute pitch. (I have no insights about this.)
I was not born with perfect pitch but I have been interested in it for years. I tried the course Jo Parker mentioned and did not find it helpful. To each his own. For me this site was more useful: http://pitchimprover.com/. I have used this to develop some level of "perfect pitch" in adulthood. But I don't have perfect pitch; or at least not "perfect" perfect pitch. My understanding from perusing the internet, which jibes with my experience, is that you can learn absolute pitch to some degree as an adult, but not "perfect" pitch. The difference being the speed of recognition and perhaps the transferability - e.g. can you perfectly identify pitches just within the timbre of one instrument, or can you do so immediately from traffic sounds? The more limited version which can be acquired later is also called true pitch. I find the terms to be terrible!
Perfect pitch of course has nothing to do with intonation when playing. My son has perfect pitch, and he plays out of tune on violin if I don't remind him. However, he can instantly identify any wrong note I play on violin! Watching his perfect pitch development was very interesting. We started him playing piano before he turned 3 years old. His teacher uses the Suzuki method, and all her students learn all the Suzuki repertoire by ear, even after they have learned to read music. (Small aside, there is absolutely no negative impact of this on music reading skills, which are introduced after the student starts reading words. And music reading is practiced using other pieces, along with learning the Suzuki repertoire by ear.) My son naturally began with simple pieces like Twinkle Twinkle. His perfect pitch was apparent fairly early, but it was limited at first to the white keys – which makes a lot of sense. He struggled learning to recognize the black keys as well, but only for a little while. So whatever was going on in his brain had the seed but needed to be trained. Next came multiple notes in succession or as chords. My son’s teacher always does a “guessing game”, which we repeat at home. The student looks away and you play some notes and they “guess” the note(s). As I described, it goes in stages – white keys, all keys, one note at a time, two notes, chords, etc.
I do think this is a useful skill. Not every child will develop perfect pitch this way – it depends on age and aptitude. But I think it will be beneficial for anyone. I have some sympathy for the thought expressed by some that it would be time better spent working on technique than trying to memorize pitches. And for an adult trying to train their ears, it might be more valuable to focus on relative rather than perfect pitch. But for a young student, ear training should be part of the overall musical training. I think violin teachers do not focus on this as much as piano teachers. The instrument is probably not as conducive, but still I think more attention should be paid to this.
To stick to the topic, train the students to hear the pitch in the head before the sound is pretty much essential, and learn the physical memory and train students to nail the finger position before making a sound. On a more advanced level, train the student to play arpeggios and listen to intervals to intervals, and I love playing scales and arpeggios with my students in different intervals. I would play 3rd higher or 6th lower (I also play chord progressions on the piano as I accompany my students on scales and arpeggios), so my student get exposed to intervals and harmonies more often. I believe this helps students to develop not just pitch awareness in relative to intervals but also they learn to play with another musician.
The ultimate training one can do essentially for free (as everyone has a smartphone to begin with) is to record own playing and listen. The weirdest phenomenon about playing the violin is the pitch perception under the ear can be so different compared to listening as an audience.
I suspect that no violinist would trade their perfect pitch for any amount of money, or the ability to do a technique they couldn't do before. I also suspect that a violinist with perfect pitch would quit the very next day upon losing it. You're not playing the same instrument without it. Relative pitch is fine and all, but what if you mess up a shift? You can't just randomly play an open string in the middle of a piece to reorient yourself...
It can really screw with you when the pitch of the orchestra changes. One orchestra may play at a=430. Another may be at a=442. A third may be a french baroque pitch of a=392.
Sometimes you play at a venue with a piano or organ that is at another pitch.
Sometimes they play in equal temperament. Other times they play in other temperaments.
You have to play at the pitch of the ensemble. But your perfect pitch says the pitch is incorrect. It can be very annoying.
This assumes that shifting is only about the aural component. That's actually the slowest transmitted data while executing a shift, and the one that the audience perceives.
The first is the visual approximation of the location of the target note, followed second by the tactile sensation of the energy expended in the movement, the type of movement and which muscle groups are used, and the contact points of the hand/arm against the instrument.
You seem to be assuming that once someone misses a shift, that they cannot find the note without perfect pitch. That's not the case at all!
Among all the string players I know in person, a significant percentage of whom are professional or semi-pro, exactly two have it.
And although a higher percentage of top soloists have it than the general population, it's absolutely untrue to claim that they all have it; there are many who don't have it, and some of those who have it say it's a handicap at times.
Relative pitch works fine because we don't just forget the sound of every note as soon as we're done playing it. It's entirely natural to think of a whole line of notes in a phrase, rather than individual notes one by one.
I'm usually able to identify notes that I hear, but it's only because I can remember what an open A sounds like while tuning, and then I just do a quick mental scale to get to the pitch that I'm hearing, and I determine the note from that.
Is this perfect pitch or no? Note that I can do it pretty much any time, even if I haven't recently heard any other notes. To me, this just seems like a highly trained relative pitch.
So what the heck is perfect pitch? I am tempted to say that it isn't a binary thing, but is simply a spectrum like most other things.
Tone-deaf is one end of the spectrum, and perfect pitch is the other. And we don't seem to have a name for everything that lies between those two extreme ends, which leads to a false dichotomy.
I can *usually* pull an A "out of thin air" but only with violin (or viola) timbre.
I can often start a song--whether violin/classical or pop or another sung genre--in the correct pitch and key; but again it's by hearing it in the context of its whole sound, intro, tone, instrumentation. Right now I have Journey "Don't Stop Believing" in my head and I guarantee you if I started singing aloud I'd be right on pitch with Steve Perry, but I have no idea what pitch that is. (I think many more people do this naturally than they realize, btw.) But if you asked me to transpose it to another key I'd have to do it relatively. If you asked me to put it on violin I'd have to translate it to violin sound in my head and I *might* get it right but sometimes I have to guess and check a couple times (and if I think about it too hard I will probably lose it.) What's that? Pitch memory? Timbre memory? Or a whole-sound association?
(By the way, I just tried it in my head, and my quick initial impression was key of A for "Don't Stop Believing", but going a little further and hearing/feeling/imagining it on my instrument I'm pretty sure it's G. Am I right? I may have to go look it up now!)
[Edit: Nope! Off by a lot! But I won't post the proper key here in case anybody else wants to try it! :D ]
They did a study, the details of which I can't remember exactly, but it involved asking mothers to play a specific tune, Happy Birthday or something like that, to their babies, always in the same key, before an event ( feeding ? can't remember ) where there would be a visible - or audible ? reaction from the baby, Once this reaction was ingrained, the mothers were then asked to play the same tune but in a different key. The babies did not react.
This to me seems perfectly logical. I was born into a household where there was a lot of music, my parents sang all the time around the house, my mum played violin to a middling level, around Grade 5. We listened to records. Aged around 2 I would apparently be lost for ages, sat between the two speakers of the record player with a stack of classical 33s playing one after the other. Any tunes I heard I would sing them in that key, I 'knew' whole symphonies and concertos from very early childhood, could run any piece of music in my head, always fully harmonised, not just the melody. Of course at that stage I didn't know what the note names were, just like learning any other language.
I started to play violin at 7, in a small group of 6 children. After a few weeks I was singled out for individual tuition as I couldn't cope with the other children's out of tune finger placement and I was physically correcting them. My teacher made the mistake of playing tunes to us before wer tried it ourselves, with the result that my sight reading was awful, I didn't need the music after hearing the tune once. I could just play it.
So, I have had many years playing violin, and piano I taught myself the Bach Toccata and fugue in D Minor aged around 10, never having had a lesson. That's what I wanted to play so I just worked it out by ear. As an adult I also learned and taught viola, cello and double bass, and more recently managed to overcome the immense difficulty of playing baroque violin/or viola/or cello at A 415. I do find it confusing after a while to convert forwards and backwards. A at 402 is do able, but I still can't play a piano or keyboard if it's transposed a semitone up or beyond A 415.
I drove a car I owned by the sound of the motor, and I guess I still do to a certain extent. My sight reading is fine now, but I struggled learning harmony as you just don't do anything the same way as someone without perfect pitch. Music dictation and aural was an absolute synch.

Most of us have relative pitch - which (at least for me) was hard work but it is very flexible.
