Composition Library

The Composition Library is your studio's repertoire: the music you teach, organized so you can find a piece and assign it to a student in seconds. Open it from Composition Library in the sidebar. The library is available on every plan.

Collections and Compositions

The page has two tabs:

• Collections - groups of pieces, such as a method book, a recital set, or a level. Each card shows the collection name, an optional description, and how many compositions it holds. Owners, admins, and teachers can add a collection with New collection, and drag the cards to reorder them.
• Compositions - every individual piece in your studio. Search by title or composer, and narrow the list with the All collections, All levels, All instruments, and All genres filters. Select a row to open the composition, or use New composition to add one by hand.

Open a collection to see the pieces inside it; open a composition to see its details, instruments, skill level, and genres.

Importing music

Two import paths sit in the page header (owners and admins only):

• Import from a book - type a method-book or anthology title and Trio drafts a piece list for you to review and save. This uses AI, so each import draws from your studio's monthly AI credits.
• Import from Trio - browse the shared Trio catalog of common repertoire and copy pieces straight into your library. Each collection and piece shows the instrument it is written for, so you can tell at a glance whether a book suits your studio.

In the book-import review step you also choose the instrument the pieces are for. Trio suggests one from the book title when it recognizes it, and you can change it. Every piece in the import is filed under the instrument you pick, which is what makes them show up when you filter your library by instrument, so the import cannot be saved until an instrument is selected.

When a collection is empty, a Get started faster - import a method book tile offers the same AI importer so you can build your first collection quickly.

Import history

Owners and admins can review past AI imports on the Imports page, which lists past imports and when each one ran.

Assigning pieces to students

The library is where pieces live; assignments connect them to students. From a student's profile Repertoire tab, pull any composition from the library and track the student's progress on it. See Repertoire for the full assignment workflow and what families see.

Files: scores, audio, and video on a piece

Open a composition to find its Files section, where you attach a score, a reference recording, or a demo video to the piece itself.

• Upload with the Upload file button. Accepted types are PDF, JPG, PNG, WebP, MP3, M4A, WAV, MP4, MOV, and WebM, up to 50 MB each. A progress bar shows while the file uploads.
• Visibility. Each file has a Visible to members switch. A newly uploaded file is saved with the switch on, so it reaches families right away - there is no visibility choice at upload time. To keep a file private, turn the switch off after it uploads.
• Download. Click a file's name to open or download it.
• Delete. The trash icon opens a confirm dialog; deleting removes the file from the piece, and families can no longer see it.

Trio Library compositions are read only until you import them: you cannot upload files or change visibility on a piece straight from the shared catalog. Import the piece into your library first, then manage its files. Owners, admins, and teachers can upload files and change visibility; staff can view a piece's files but cannot upload, toggle visibility, or delete.

A family sees a composition's library file only when Visible to members is on and the piece is assigned to one of their students. These files open on the piece's detail page in the family's Resources > Repertoire view; they do not appear in the Materials library. Files on a library piece show only on that piece's page. For the full picture of what families can access and where, see Sharing Files with Families.

Who can do what

• Owners, admins, and teachers can create and edit collections and compositions, and upload or change the visibility of a composition's files.
• Import from a book and Import from Trio are limited to owners and admins.
• Staff can view compositions and their files but cannot upload files or change visibility.
• Members never see the teacher library; families see only the pieces assigned to their own students.
