Library overview

The four library tabs

The library opens on a row of four tabs. Each one changes which scores the list below shows — your grouping, filters, and search carry over unchanged when you switch.

Note: Calibrated pieces have their own tab instead of a filter chip — there is no "Calibrated" entry in the filter row.

Group the list

On a fresh install the list is grouped by Period, with Composer and then Form nested inside each era. That arrangement is the built-in Period · Composer · Form view (see Saved views); you can change any part of it.

The Group by row sets the top-level grouping. Tap one of:

• Composer — one section per composer.
• Recent — most recently opened first.
• Period — sections by era (Baroque, Romantic, Impressionist, …).
• Form — sections by form (sonata, nocturne, fugue, …).
• Instrument — sections by instrumentation.
• A → Z — one flat alphabetical list, no sections.

Nest a second level

To divide each top-level section further (for example Period, then Composer inside each era):

1. In the Group by row, tap Add group.
2. Pick an axis: Period, Composer, Form, Instrument, Tonality, Year, A → Z, Catalog, Favorite, or Duration.

The new level appears as a chip after the top-level grouping. Tap the chip to adjust it:

• Group by — swap this level to a different axis.
• Show as — how the sub-sections render: New panel, Sub-column, Open section (always expanded), or Drop-down with a Collapsed or Expanded default.
• Remove — delete this level.

You can chain several levels; the whole arrangement persists between launches.

Filter the list

Tap FILTERS to expand the filter chips (tap it again to collapse them). Chips appear in this order: Instrument, Period, Form, Difficulty, Importance, Tonality, ⭐ Starred, PDF only, XML only. Each chip opens a small panel; active chips stay highlighted.

• Instrument, Period, Form, Tonality — pick any number of values. Tonality lists all 30 major and minor keys, plus any other key spellings already present in your own files.
• Difficulty — one band at a time: Beginner, Intermediate, Advanced, or Virtuoso. Picking a second band replaces the first; tapping the active band clears it.
• Importance — an editorial 0–100 score of how central a work is (50 Notable · 75 Major · 90 Canon). Separate sliders filter by piece importance and by composer importance.
• ⭐ Starred — only pieces you starred.
• PDF only / XML only — only pieces whose file is a PDF, or only pieces with playable MusicXML.

Tap the ✕ at the end of the row (Clear filters) to drop every active filter at once.

Limit: PDF only is available only on the My Library tab.

Search

The Search… field matches every word you type, and it understands structured terms, so you can mix them freely:

• Composer — tolerates typos and accents (chopin, debusy).
• Year — a 4-digit year matches works composed around it; if nothing matches the exact year, the search widens to the era (1722 surfaces Baroque works).
• Era, form, key, instrument — baroque, nocturne, c minor, violin.
• Catalog number — BWV 846, Op. 27 No. 2, K. 331.

For example, chopin nocturne c minor narrows to exactly that intersection.

Saved views

A saved view is a snapshot of your grouping chain and every filter. Views live as chips on their own row above Group by; tap a chip to apply it. The app ships with one built-in view, Period · Composer · Form, which is also the fresh-install default — you can't rename or delete it, but your own views sit next to it on the same row.

To save the current arrangement:

1. Set up the grouping and filters you want. As soon as they differ from every saved view, a 💾 Save this view chip appears at the end of the row.
2. Tap it. The view is saved immediately, named after its grouping chain.
3. To pick your own name, long-press the new chip and choose Rename.

Long-pressing one of your view chips also offers Update with current view (overwrite it with the current arrangement) and delete.

When your current arrangement already matches a saved view, the end of the row shows a + chip instead: it clears everything to a blank template (flat A → Z list, no filters) so you can build a new view from scratch.

A saved view does not record which tab you were on or your search text, so one view works across tabs. Saved views sync to your other devices through iCloud.

Where to go next

• Organize — merge duplicates, link sets, combine movements, and let the cleanup assistant suggest fixes.
• Collections — group pieces into named collections and setlists.
• Metadata — fix titles, composers, and how titles are formatted.
• Sync — what syncs across devices through iCloud, and what stays on this device.
