Terms of use

Last updated: 2026-10-12.

These terms are an agreement between you and Matheus Teixeira, Brazil, who runs Amadeo. By using the site you accept them. Questions: contact@amadeosheets.com.

Using Amadeo

The free features are open to anyone, without an account.

Your sounds and scores

What you open, record and write remains yours. You must have the right to use the sounds you give Amadeo. Writing down copyrighted music for your own study and practice is the purpose of the site, but sharing, selling or publishing a transcription or arrangement of someone else's music can need the permission of whoever holds its rights. That is your responsibility.

The analysis

The scores Amadeo writes are estimates made by a neural network and by music analysis. They can contain mistakes, so check a score before you perform or publish it.

The repertoire

The arrangements in the repertoire belong to their arrangers. You may play, record and perform them, including in videos you earn money from. The score files are for your own use: please do not sell or republish them.

Videos

You may publish the videos you make with Amadeo anywhere, including on channels that earn money. The rights to the music in them are yours to clear.

Pro

Pro is sold through Paddle, our merchant of record, so Paddle's buyer terms also apply to the purchase. It starts with a free trial of 14 days: nothing is charged before it ends, and we email you three days before it does. It then renews each month or year until you cancel. You can cancel at any time and keep Pro until the end of the period you paid for. The price you join at is the price you keep for as long as your subscription runs. Refunds follow the refund policy.

Fair use

Do not attack or overload the site, copy it in bulk by automated means, or use it for anything unlawful.

Responsibility

Amadeo is offered as it is. As far as the law allows, our responsibility for any loss is limited to what you paid us in the twelve months before it. Nothing here limits the rights consumers have where they live.

Changes and law

When these terms change, the date at the top changes too. They are governed by the laws of Brazil, without taking away the protections of the country you live in.
