Make beautiful music

We aim to make playing music as easy and trouble-free as possible.
For any musician.

What is Gustaf?

  • A market place for digital sheet music

    Gustaf is a market place for digital sheet music. We offer both an online store and web application enabling you to buy and use digital sheet music securely and legally. The Gustaf Store contains a music collection of more than 150,000 scores from various publishers.

    Our scores are interactive and can be edited on every device or operating system, in our web and mobile app. The application offers an array of features to improve the experience of performing music. For instance, there are various view tools (mark, zoom, edit, notes, transpose, etc.), a metronome function, tuning device, etc.

    Gustaf works both online and offline. It is available for any web browser and iOS and Android devices. This way you have access to your scores at any time, wherever you are.

Musicians of all kinds

You don’t need to have a band, a studio or an audience to be a musician; it starts with you and your instrument. We provide the score, you provide the music.

  • You can choose and purchase your sheet music in our Gustaf store.
  • You can view and make edits to your sheet music in our your personal library.
  • No need to lug around heavy books. Everything you need is available in your digital library — even without an internet connection.
Musicians of any kind
Choirs and orchestras performing with Gustaf

Choirs, ensembles and orchestras

Playing music together is a great feeling. However, making copies of sheet music for every choir or orchestra member can be messy and frustrating. We facilitate distributing between members of an orchestra or choir. The only thing your members need is a device to access the score. No more parts getting lost in rehearsal rooms or concert halls!


Schools & Teachers

We understand the importance of educating the next generation and carrying over our love of music. That’s why Gustaf is perfect for students!

Our wide array of features allows a teacher to make as many edits to a score as you can imagine, from fingerings to big red circles and exclamation points.
Instruments can be tuned through our tuning device in the app. Teachers can purchase scores, but upload their own arrangements as well.

The perfect hardware for musicians

Looking for a tablet, music stand, or another accessory for the demanding digital musician? We want to make sure you can take full advantage of the Gustaf App and our digital sheet music in the Gustaf App. We get a lot of questions about what is the perfect set-up for a musician with digital sheet music, and we have experience with most commonly available iOS, Android and Windows tablets.
