I dont know why but i just had to make sure that it was the saddest music note.
Yep it is the most saddest of all. Unlike the mighty G that sounds the best.
all keys sound different cos scientifically a c sharp is not the same as a d flat etc, so if you play it on a piano (or any fixed note instrument) you get slightly different intervals
lemonbade: maybe that's why different keys/chords on a piano sound different (apart from the pitch i mean), as in for some keys you get better intervals than for others. am i being vague enough?
