Sharps and Flats
Let’s take a look at sharps and flats on the piano.
What Is a Sharp on the Piano?
This is what a sharp sign looks like:

When the sharp sign appears after a note (as in “C♯”) it means to play the note 1/2 step up. That means to play the note just to the right (in this case, a black key).

Sharps won’t always indicate black keys. If you were to play B♯ it would actually be a C (a white key), since C is 1/2 step up from B, or just to the right of B.
You may wonder why a note would be called “B♯” if it’s actually a C? That’s a good question! It will make sense when we move on to learning how to build major scales.
For now, the important thing is understanding that the sharp sign means to play the note 1/2 step up (or just to the right), whether white or black.
What Is a Flat on the Piano?
This is what a flat sign looks like:

When a flat sign appears after a note (as in “E♭”), it means to play the note 1/2 step down. That means to play the note just to the left (in this case, a black key).
Flats, like sharps, don’t always indicate black keys. They just tell us to play the key 1/2 step down, or just to the left, whether black or white.
Now It’s Your Turn
To reinforce this, you can practice finding different sharps and flats on the piano. First practice finding all the C♯ notes, then move on to all the D♯, E♯, F♯, G♯, A♯ and B♯ notes. You can do the same with flats.
