Well, I am glad that you don't sing in my hearing range then and you should 
throw away that tuner.

A semitone difference is quite noticeable.

A semi tone difference is indeed noticeable but surely there is no semitone 
between e sharp and f flat?
It’s the same key on the piano! Where is the semitone? 
Instead of enlightening me you simply reply with a superior and dismissive tone 
which is uncalled for.
