# Beats & pitches grid

Let's take a look at the main editor without any notes:

It's a two dimentional grid. There are two X axes (time) and one Y axis (pitch).

## Grid axes

1. The Y axis corresponds to pitches (pitch is represented by a number from -60 to 67)
2. The lower X axis represents time in beats (beat is the smallest unit of time in Ultrastar format, see [bpm ](/karedi/next-level/txt-file-format/tags/bpm.md)article to learn more about beats)
3. The upper X axis represents time in ms. This axis is purely informational for you as humans understand time in milliseconds better than beats.

## Grid lines style

The lines creating the grid are dashed. The vertical lines corresponding to every 4th beat are solid. The thick vertical line that you can see in beat 3 is the [time marker](/karedi/user-interface/middle-components/main-editor/time-marker.md).

## Visible range

The range of values visible on any of the axes depends on several factors - mostly the current display mode and the notes. You can read about that in [visible area](/karedi/user-interface/middle-components/main-editor/visible-area.md) section.

## Blue grid

The light blue color of the grid's background marks the time range of the [medley](/karedi/creating-songs-for-beginners/finishing-touches/medley.md).
