How it works
Structure the ensemble. Define works.
Organize events. Read the Ensemble lineup.
Arko connects your ensemble structure, your repertoire, and your events. Every piece of information you enter directly supports musical organization.
Every event generates the information that matters. A schedule update or an unavailability instantly triggers targeted notifications to the responsible members and the musicians concerned. Everyone receives the information that concerns them, exactly when it matters.
Structure the ensemble
Define sections, subsections, and roles exactly as in your real organization.
- Enable sections (Strings, Woodwinds, Brass…) and subsections (Violins 1, Flutes, Horns…).
- Distinct roles: Owner, Administrators, Music direction, Musicians.
- Self-onboarding via invitation code: members assign themselves to their section upon joining.
Standard foundations, complete flexibility
The creation of your ensemble is guided by a setup assistant and a recognized reference library of subsections and instruments.
Your sections can rely on these references to structure your roster quickly and consistently. If needed, you can also create your own subsections or instruments to accurately reflect the specific reality of your ensemble.
Internal subsection details
Detail each subsection down to its internal instruments to know exactly who is playing what and finely model your ensemble's reality.
Advanced status management
- Distinction between regular "Permanent" musicians and an unlimited pool of "Extras".
- "Silent" profiles by default, not called to regular ensemble events.
- Extras stay silent by default and are invited only when needed, with explicit response tracking.
Master the repertoire
Each work has its own record: title, composer, arranger, shared resources.
Detailed instrumentation
Define precisely the subsections and the number of required musicians (e.g., 2 flutes, 2 oboes).
This definition enables:
- Comparing instrumentation to the ensemble's permanent musicians.
- Immediately identifying uncovered positions.
- Applying these needs to events linked to the work.
Instrumentation templates
Save time by saving a typical instrumental configuration to reload it on other works.
- Concerto: Save 1 reusable instrumentation template.
- Symphony: Build a library of 30 instrumentation templates.
Organize rehearsals and concerts
Set the date, venue, and program. Relevant musicians are targeted automatically according to their assignment and the nature of the event.
- Call lists by section from the Basic plan.
- Detailed call lists by subsection or instrument from the Suite plan.
Automated call lists
The event automatically reuses the needs defined in the work's instrumentation to precisely target the required musicians.
For concerts, this call can become an explicit response workflow: confirmed attendance, decline, or pending response.
Nominative instrument assignment
The administration can assign each musician individually to a specific instrument or subsection.
This assignment generates a clear and named roster of the expected performers. Musicians who are not assigned are therefore considered not called for the event, ensuring immediate clarity and precise control over the performing lineup.
Required vs actual
For rehearsals, the called lineup is assumed available unless unavailability is declared. For concerts, invited musicians confirm or decline their attendance.
- From the Basic plan onward, quickly view absences, availability, and overall lineup status.
- The Suite plan refines that visibility with greater detail, down to declared subsections and instruments.
Fine control of the lineup
Without instrumentation: immediate operational visibility on called musicians.
With instrumentation: detailed analysis of actual needs, gaps, and extras to mobilize.
Concert and rehearsal attendance sheet
Validate your roster's actual attendance for concerts and rehearsals with a dedicated attendance sheet, exportable to CSV.
