Hehe... yea... most of the people don't get it at first...
You see, B# is not the same as C. It may be the same tone, but it's not the same note
As you probably know already, there are half steps and full steps, AND
while going through the scale you have to have ALL the notes in there
(when i say all of them i mean C D E F G A B C with sharps or flats if needed).
Lets take a C major scale:
C D
E F G A
B C with half steps between III-IV and VII-VIII right?
Now let's take it a full step up to D major:
D E F G A B C D - We have all our notes here, BUT now we have to "apply" the
rule from above - Half steps between III-IV and VII-VIII.
If you look at your keyboard you'll see that the final result will be:
D E
F# G A B
C# D
If you go another full step up to E major you'll have:
E F G A B C D E (all the notes here), apply the "halfstep" rule for major scales and you'll end up with:
E F#
G# A B C#
D# E
Ok, enough with the shaprs now
Let's see what's with the flats.
Let's take the F major scale and see what happens:
F G A B C D E F (all the notes here), applying the "rule" from above and we get:
F G
A Bb C D E F
Notice how
it's not F G
A A# C D E F even though A# and Bb are the same tones, they're not the same notes
The same thing goes for the rest of the scales. Min, Maj, Dim, Sus... etc etc.
You have to have all the notes in there, and then you apply the rules for the scale you're in.
Of course if somewhere within a song that rule is not applied it is marked in the sheet. for example
if in D major (D E
F# G A B
C# D) and for some reason you need to play F instead F#.
I hope this clears it up a bit
Now for your homework... try figuring out what NOTES are in F# Major scale and Eb major scale
