D♯ A♯ E♯ B♯ and you will know that the previous score below is just like this:
Finding the name of the key signature
With the sharps order, you can find the name of the key signature:
Imagine you have this (3 sharps in the key)
With the order of sharps, you have this: F♯ C♯ G♯
You find the last sharp in this sequence: F♯ C♯ G♯, here it is G♯, and you add a half step (semitone ) to know the name of the key signature: G♯ + 1 half step (semitone) = A. So with 3 sharps in the key, the name of the key signature is A Major.
