Reh. AThe problem

Your parts change every rehearsal.
Nothing tracks what changed.

A new bowing from the principal. A penciled-in fingering. A subito p that wasn’t in last week’s edition. They land on the stand the morning of the concert, and the section finds out one stand at a time. Varius gives your library one place to mark parts, keep every revision, and send them to the section.

An average full-orchestra classical program can involve 3,000 pages of music to prepare, with librarians most often working on at least eight different programs at once.

But what about players who want to stay on paper?
Reh. BPaper or iPad

No all-or-nothing decision.

Some sections stay on paper. Some move to iPads. Some do both in the same rehearsal. Varius works underneath without asking anyone to change how they rehearse.

On paper

Players mark in pencil as always, and can open the digital part as a practice copy or a reference. The librarian keeps the record.

On iPad

The principal pencils a bowing* and every other stand sees it instantly. Players keep their own layer of personal markings.

Both

Same section, same rehearsal. Markings reach whoever's on iPad; paper players work as they always have.

Reh. CThe library

Every piece. Every part. Every version. In one place.

Finding the changes isn’t the end of the work; every revision becomes an entry in an archive. Years from now, when a piece comes back into rotation, you’ll know exactly how you played it last time, down to the bowing on every desk.

Reh. DBuilt for everyone in the room

One system. Three perspectives.

Librarian

The back office

Runs the library and the season. Everything the section sees starts here.

Cycles
Program each ensemble’s season, schedule when parts publish, then seal a cycle once it’s performed.
Catalog
Every piece with its editions, baseline parts, marked versions and full version history. Export all of it whenever you want.
Seating
Stands, principals and per-piece personnel, down to doublers and covers.
Team
Invite players one at a time or from a CSV. They’re emailed when their part changes.

The section’s markings

Stand one owns the section’s shared layer. Mark the part right in the Varius app: each new bowing is read, labeled by measure and sent to every stand. Marked parts from another app, like forScore, can still be uploaded.

Section member

The stand

Every assigned part, across ensembles, always the latest. The principal’s markings arrive live; their own markings stay on a personal layer.
