Gustaf works across device & browser

Every score you buy or upload is stored instantly in the cloud in your personal Gustaf library. It’s available anytime, anywhere on your preferred device. You don’t have to switch browsers or always be online—or wait to play music. Discover our web application or download Gustaf from the App Store or Google Play for free.

Rehearse and perform offline too

Sometimes your Internet connection just lets you down. Or maybe you don’t want to be disturbed and distracted by other notifications. That’s why Gustaf allows you to rehearse and perform in an offline mode. Just choose the scores to be played offline beforehand. Oh, and you can also switch on concentration mode to avoid all notifications, as well hide toolbar and buttons.

Better than paper sheets

Paper gets lost, torn or ends up full of pencil marks and coffee stains. And nothing is more aggravating than being in the middle of a performance and watching a paper flutter to the floor. Music flows beautifully in the Gustaf App and never goes missing. No need to print. But if you insist, you still can.

Interactive features


Enrich your performances and practice more efficiently. You can highlight the tricky parts or hide the other voices if you have a piece for ensemble but only want to see your own staff.


Like you do on paper, you can note articulations, dynamics and fingerings or make a free text annotation. You will no longer miss the spot where you keep forgetting that sharp!


Instantly transpose the full piece if you decide to play it in a different key. Automatically configure steps up or down in a flash.


Organize your scores in setlists for any occasion you want, whether it’s for rehearsal or performance.


With playback you can hear what the piece is supposed to sound like.

Responsive Interface

Regardless of your device, music scores flow smoothly. Zoom or highlight staves for effortless reading.
