We’ve got two new features to announce today: lyrics and support for multiple synced videos.

First, we’ve added support for lyrics in our music notation. Here’s what they look like:

As with the rest of our interactive notation, you can toggle lyrics on and off. To do that, click the track name at left and click the lyrics icon:

Behind the scenes, the display of lyrics is a bit more complex than you might think. Depending on the length of the word/syllable, the notation engine needs to tweak the spacing of the associated note(s), such that lyrics can be properly centered under notes while preventing words from running together.

We also support extenders, which is the fancy name for the horizontal lines that extend from words that are sustained over several notes. And of course, everything works seamlessly with our “responsive” notation, which means it repositions everything depending on your screen width.

Here’s a demo of our lyrics in action: Take Me Out To The Ball Game.

This particular example also shows off the second new Soundslice feature — a single piece of music that’s synced with multiple performances. In this case, we’ve hooked the notation up to 33 different celebrity performances of the tune at Wrigley Field in Chicago. You can switch between them in real time by clicking the celebrity name at the bottom.

Obviously this tune is a silly example, but the ability to switch between performances is super useful for learning a piece of music. This lets you, for example, select a few bars of a piece that you’re having trouble with, then toggle through different musicians’ approaches to that same passage. It’s really powerful. Stay tuned for more!
