Why keys are not embossed in braille?

No, I am not blind however, if the keys were marked somehow (braille or other) it could have been much easier to know which key is what for the beginners.

This is somewhat similar to how F & J keys on computer keyboard has some raised bars to let you know where to find them without looking at keyboard.

Off topic - this is a problem with smart phones too (without touch screen). I like the old Nokia phones where you could easily press keys to launch apps without even looking

I reckon since the position of black and white keys already give the blind a contour to feel.

Maybe there's a gap in the market! Oh wait, no there isn't.

Lol. Do some research! I expect either;
A - The demand by blind pianists is either not high enough, or simply not cost effective
B - Blind people can make do without the braille keys as mentioned below the arrangement of black keys makes that easier, if we don't need to look down to play, it makes no difference.

There is braille music however interestingly enough. https://braillebug.afb.org/music_braille.asp

With regards to smart phones, I think again the demand would not be high enough. I'm not blind and certainly don't have experience on a blind way of life, but I cannot imagine that many are utilizing smart phones for much more than texting and phone calls and so probably make the most from the voice recognition rather than braille here.

A church organist friend of mine was blind (he's passed away now).  No problem at all with playing the instrument -- but then organists, as a group, rarely look at the keyboard or pedalboard anyway.  It's all done by feel.

And, IMHO, it wouldn't be a bad thing for pianists to do that, too!

I don't know that braille on the keys would help the blind... I think it would be like writing the note names on the keys for sighted people... sure you can do it... but does it help?  not really... if anything it's a crutch.

There are self stick tactile dots that can be stuck on non braille items for people who have low vision or blind.

I don't quite get the question.  You have this huge two black keys sticking up a mile high, and another huge three black keys sticking up a mile high.  Any tactile braille would be a flyspeck in comparison.  D is always the key between the two black keys.  C and E are on either side, same as the alphabet.  I couldn't see a need for it.

yes because the tactile landscape of the piano is plenty...more than enough.  

Music written in braille is a whole different thing... and it is so impressive to see someone read music in braille...then play it.  I have only seen it once and it was at school of course.  The man ran his fingers over the page and then played the whole thing.   Now...THAT is sight-reading...or blind-reading...or IDK... but he read it...committed it to memory and played it all in about 15 seconds.  It was a newly written piece that had been composed by one of this man's (blind) piano students that he was playing for the first time.  He did not play it by ear.

He also could run one hand over the page and play the melody with the other...it was too cool.
