Creating and editing content on Soundslice

Soundslice lets you create sheet music that’s synced with audio/video recordings — with beautiful, easy-to-use practice tools built right in.

Here’s our comprehensive help section about how to create content on our platform. You can do a lot with it! Let’s dig in.


Every piece of music on Soundslice is called a slice.

It doesn’t matter whether it’s a single-bar blues guitar lick, a full orchestral score or something in between.

Soundslice is all about slices — creating them, sharing them, selling them, embedding them. Slices are the fundamental unit of this site.


A slice can have one or more recordings. A recording is an audio or video file that’s been synced with the sheet music.

When you add a recording to your slice, you really unlock the power of the Soundslice player — making it possible to navigate the audio/video by clicking on the music, create loops by dragging over the music, use synced instrument visualizations and a lot more.

A slice can have multiple recordings — such as backing tracks, different camera angles or even different performances (with different tempos) of the same piece.

The slice manager

The slice manager is the part of our website where you create slices. You can always access it by logging into your Soundslice account and clicking “Manage” at the top of any page. Here’s a direct link.

Creating slices

There are two aspects to creating a slice: providing the notation and the recording(s).

For the notation, you can either:

  • import an existing file, if you use other notation software, or
  • use our excellent notation/tab editor to create from scratch

You can mix and match these approaches — for example, importing a file from another program, then using our editor to make changes directly within Soundslice.

For the recording, you can use a YouTube video, or upload MP3s or video files directly to us. We support a few other video services as well.

After providing the recording, the final step is fast-and-easy syncing. You use our web-based syncpoint editor to specify how the sheet music should be aligned with the audio/video.

Different approaches

Soundslice supports a variety of approaches in creating slices. Here are some possible workflows:

  • Start with an existing notation file, then sync a video with it.
  • Start with a video and use our editor to transcribe it.
  • Enter some sheet music, and leave it at that. Without a recording, our player will fall back to synthetic playback.
