i get easily confused with the fact that you can call the note F# either F# or Gb. why don't we just have it so each note has its own distinct name? so it goes ABCDEFGHIJKL instead of A Bb B C Db D Eb F F# G Ab.  i know im not the first person to think of this and obviously it would mess up the whole system we have right now but i still think it should be changed!
i made a system like that many years ago, i decided F#, Ab, Bb is Q R S. and C# and Eb are J, K.  i did it so i wouldn't have to forget the existing letters. i think it's a perfectly fine system but it fell into disuse because no one else was using it
