Josie,

I know this response strays a bit from the topic or at least the intent of the topic, but it has 100% to do with perfect pitch.

Not sure if you have heard Image and Family on the online site at which I perform from time to time, but the son, Robert has perfect pitch. Robert is also Autistic, but learned all of his major and minor chords on his keyboard in less than one hour.

But what really blows me away is when his dad kicks off a tune and Robert, after hearing just one note of the intro turns around and says "wrong key".

Bottom-line is that it never ceases to amaze me when I hear someone define a note just by hearing it.

Later,
