How to read this glossary

Words in inline code are the exact labels used in the app. Controls named in plain text have no visible label on screen.

Library and organization

Library<br> The pieces you have imported or added. The library view can switch between your own library and the Catalog.

Catalog<br> The online score collection browsed from the Catalog view of the library. Catalog scores are served live, so browsing them requires a network connection.

Piece<br> A musical work in the library. A piece can contain several score versions and takes.

Collection<br> A user-defined group of pieces, created with New collection…. A collection groups pieces for browsing; it does not merge their files.

Take<br> An audio recording associated with a piece. New takes are named Take followed by the recording date and time. A take can be replayed and, when prepared, used as a calibration reference.

Scores, formats, and versions

Score version<br> One stored representation of a piece, such as an imported PDF, MusicXML, MEI, or MIDI file, or a converted Smart Score. Activating a version determines which score the reader and compatible tools use.

Open as<br> The switcher that changes which score version an open tab displays. It is reached from the tab's format badge (PDF, XML, and so on).

PDF<br> A fixed-page score. It preserves the source page layout and supports direct page reading and annotation. In Toolbox, Rearrange pages, Crop, and Dewarp & Clean need an editable PDF; Share and Print need a PDF or MusicXML version.

Smart Score<br> Structured notation used by notation-aware tools such as Transpose. A Smart Score can be imported as MusicXML or MEI, or produced from a PDF with Convert to Smart Score.

Conversion<br> The network workflow started by Convert to Smart Score in Toolbox. It reads a PDF and creates structured notation; importing a PDF is not conversion. If the result contains recognition errors, use Fix a Wrong Conversion in Toolbox.

MIDI<br> A .mid or .midi file. On import it is converted to structured notation, and the original MIDI file is kept with the piece.

For per-format import roles and limits, see File formats.

Reader

Tab<br> One open score in the reader. The Open tab limit stepper in Settings caps how many tabs stay open at once.

Toolbox<br> The reader's tool panel. It holds score actions (Table of Contents, Follow preset, Convert to Smart Score, Fix a Wrong Conversion, and the page-editing rows), practice tools (Metronome, Tuner, Transpose), accessibility input (Bluetooth page pedal, Face gesture page turning), app and paper themes, and the Assistant, Sync now, Report a problem, Support, and Settings rows.

Assistant<br> The Assistant row in Toolbox opens Ask the Score, a chat about the open piece. Its preferences in Settings include an on-device Apple Intelligence option; on supported devices it runs on the device itself at no added cost.

Lab<br> The live analysis surface with real-time audio processing and graphics — the heaviest optional feature. Disable the Lab in the Performance section of Settings turns it off without affecting the reader or the tracker.

Follow and calibration

Follow<br> The live workflow that aligns microphone input with the prepared score and can move the tracker or turn pages.

Follow preset<br> The Follow settings for the open score. Open them from the Follow preset row in Toolbox or the Follow tab of the reader side panel — both show the same surface.

Tracker<br> The visible position indicator used during Follow or score-linked playback. It can be hidden, shown as a band, or combined with note dots where supported.

Anchor<br> A confirmed connection between a performance position and a score position. During Follow, the anchor button in the reader corrects the tracked position after a drift: tap the anchor, then tap the note you are on.

System<br> One horizontal row of staves on a score page.

System band<br> A calibrated rectangle identifying the visible bounds of one system on a PDF page.

Calibration<br> Saved mapping between a score layout, its systems, timing, and a take or Follow reference. A new edition or page layout can require another calibration.

Reference pitch<br> The A frequency used by the Tuner, set with Reference pitch in Settings.

Annotation

Annotation<br> User-created ink, text, fingering, mark, or other object placed on a score. With Draw with Apple Pencil anytime enabled in Settings, touching the score with the Pencil draws without entering an annotation mode first.

Layer<br> A separately visible group of annotations or generated notation, such as personal ink, fingering, or analysis.

Fingering<br> A finger-number mark (1–5) on a note. Fingerings can be generated as recommendations or written by hand; with Recognize handwritten fingerings enabled in Settings, a handwritten digit 1–5 becomes a fingering mark and a scribble over a mark erases it. Revise re-opens passage selection to request a new recommendation for a passage.

Storage

Files provider<br> A storage location exposed through the iOS or iPadOS Files picker, including iCloud Drive and enabled third-party providers.

iCloud backup<br> The copy of your library managed by iCloud Backup & Sync in the Sync tab of Settings. It is not a browsable folder in iCloud Drive; restore it with Import from iCloud.

For control locations, see the Settings reference.
