# Piano

The pitches in Ultrastar are represented by numbers from -60 to 67 with 0 being C4 sound. Because these numbers may mean little to you, the little piano keyboard on the left side of the [*main editor*](https://karedi.gitbook.io/karedi/user-interface/middle-components/main-editor) can be helpful.

## Checking the tone

In the example above we can see that *Can* note's pitch is 5. But what is 5?\
If you take a look on the piano keys you will see that 5 corresponds to F (also called *fa)* soun&#x64;*.* You can also hover your mouse on any key in the piano keyboard to learn what sound it represents.

All C keys have a red dote on them to make them more distinctive.

If you are unsure about the meaning of the number representing the pitch of some existing note, you can also just hover your mouse over the note.
{% endhint %}

## Trying out tones

You can also click on any key on the piano keyboard to hear what sound that key represents.

## Hiding the piano

To hide the piano go to the menu and choose *View* -> *Toggle Piano* action (or use `ctrl + b` shortcut).
