My child studied the Yamaha music program which starts at age 4 or 5 and emphasizes singing everything using fixed do solfege similar to Suzuki but with group classes
They developed white key absolute pitch meaning they can recognize any natural tone by ear and can sing any pitch from memory.
Many of the students developed some form of absolute pitch.
However, I am not sure the utility of the skill. I am into jazz and tried to teach them some improvisation and they never showed a great aptitude or interest for it and they also struggle with relative pitch tasks, essentially converting the notes they recognize into the interval.
In short, I came to the conclusion that absolute pitch recognition by itself won't make you a great musician.
