Testing for perfect pitch

It’s essentially just a particular recall of sound. It can be very useful as a musician, but most musicians develop it to some extent anyway - e.g. being able to accurately sing the note “A”. I think the violin teacher might not be great if she can’t work out for herself whether or not your daughter has it.

I don’t think you need to test for it? As in does a test add anything? DS has it (he’s 9 ) and it can be handy as was next door when I was trying the recorder and he called out that was meant to be C#! His singing teacher found he can sing a note if you name it. I guess it probably shows a musical aptitude

Most singers/instrumentalists learn this...yes it is a skill but only really in musicianship. There’s no “test” for it. X

The only time I know of it being tested was in an audition for Chet's.

It's useful when you're out carol singing and have forgotten the tuning fork

Apart from that, not massively. My brother has it and when he was little he had terrible trouble every time we decided a piece would be easier for us to sing if we moved it up or down a bit.

After ten years of string playing I reached the point where I could say whether a note was A or not (like SwayingInTime's daughter).

My son developed it (found out quite by chance when we were singing in the car - "I think I may have started that a bit too low" "yes you did Mummy, perio should be on an A").

It's not a particularly useful skill but it's an indication of a good ear. I don't have it (except as mentioned above) but my knowledge and experience of singing means my sight-reading is very good (pretty sure it's at least as good as now-adult son's). On the other hand, I had a friend at university who had never learned to read music but I discovered that she had perfect pitch without even knowing that it was A Thing

I would have thought that a violin teacher would be able to 'test' quite easily for it? Or is your daughter very young and doesn't know the note names? There have been studies identifying perfect pitch with non musicians but like you say, it's all a bit abstract and academic. I would imagine it would be very helpful with learning the violin though!. FWIW my daughter goes to a specialist music school and says less than half of her classmates have perfect pitch. She doesn't but has trained herself to recognise and reproduce the open string notes of her instrument for fun (they're an odd lot!).
