Pallas But I do think I hear and note and try to sing it, and I can hear that I failed!
Interesting! Thanks for mentioning that Pallas! I previously assumed that everybody has that particular natural ability. Or at least most people have that naturally --- as in if somebody else sings a particular pitch like 'laaaaAAAAAA', then usually another person can immediately and directly sing - with their voice - the same frequency 'laaaAAAAAA'. I will have to look more into this - as in getting some stats on that. But - in any case - as mentioned somewhere else in the forum - it's piano and music that got us all to here to Piano Tell. That is amazing in itself. Internet plus modern computing and digital audio power, piano plus music etc, got us all here.
[update] - back again --- I just got this information here, and don't know how accurate it really is. I'll keep looking though. But I really and actually assumed that pretty much every body - toward the 100% mark - can/could naturally match somebody else's pitch immediately - right away. This article here reckons it's an approximate 50-50 split. Not that it actually matters. Just getting in there in any which way to play pianos is what it is all about.
