# Tempo parameter

The higher the parameter, the faster the music. Simple.

But there's more. We use bars for the logical composition of music. It needs a certain number of bars to be logical. Music usually uses multiples of 4 (4, 8, 12, etc.).

The shorter the song, the harder is to get the right bar count. So this parameter has less effect on shorter tracks.

The **slower** tempo is on **value 1**, the **highest** on **value 9**. The default value is 5.

Best practice: Don't use it too much for short tracks (under about 30 seconds). It works perfectly for music over 1 minute in length.
