Let's try a more difficult key. Let's try
the B key.  This one has a lot of sharps.
You don't have to worry. Now you know want to do. Put the B in 12 o clock
position.
Write down the note on the left. It is
the E note. B F# C# G#
D# and A#.  Right away
You see that there 1 2 3 4 & 5 sharps here.
You rewrite this in alphabetical order
& you play the scale on the piano
B C#  D#  E  F# G# and A#
This should be A#.
