Looping music is one of the best ways to practice. Get your instrument (or voice), loop a recording of your teacher (or favorite artist) and play along, trying to match their pitches, tone and timing.

Creating loops

If you’re using a computer with a mouse, just click and drag anywhere in the music to create a loop. From then on, playback will be limited to the section you’ve selected.


As you drag across the music, we’ll automatically “snap” to notes, rests and barlines — making your loop nice and tight. And we’ll fade out the rest of the notation, letting you focus on the specific section.

Resizing loops

Adjust an existing loop by clicking and dragging either its left or right edge.


Clearing loops

To clear a loop, just click or tap anywhere in the notation.

Looping on mobile devices

To create a loop on a smartphone or tablet, first tap the “Loop” icon in the control bar. This will create a loop in whatever measure the playhead is currently in. From there, you can adjust the starting and ending points by tapping and dragging.


The loop menu

When a loop is active, you’ll see the following little menu appear toward the bottom of your music:


This tells you which bars you’re looping — “Bars 11-12” in the above image — and it has a few buttons:

Play a looped area just once

If you’d like a selected passage to play only one time through, click in the loop menu and select “Play loop only once.”

This might seem counterintuitive — to play a loop once — but it can be a handy way to practice. At your own speed, you can start the same passage over and over without having to manually navigate to the start of it each time.

How precise is the looping?

Loop precision depends on the type of audio that’s synced with the slice. Here are the various cases:

Slice audio Looping behavior
Audio-only (with “enhanced slowdown”) Loops are perfect, to the level of audio sample, and will sound identical each time through.
Audio-only (without “enhanced slowdown”) Loops are nearly perfect; their duration may differ by a few milliseconds each time.
Video Slight delay between each loop iteration, depending on video quality and length of loop.
Synthetic Loops are nearly perfect; their duration may differ by a few milliseconds each time.

If you’re creating slices and want to enable the most precise loops possible, use an MP3 as opposed to a video. Or, hey, why not do both — offer a video and an MP3, and let people switch between them.
