# Practice loop with tempo increase

Loop selected measures with gradually increasing tempo! This is perfect for practicing exercises or difficult passages - start slow and build up speed progressively with each repetition.

Select the bars to be looped, then choose **Practice selected bars...** in the bar popup menu:

Adjust the start/final tempo and the number of loops, then click on **Create Song.**

You're ready to play the song and start practicing! You can save this practice song if you want to reuse it.
