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.
Structure the ensemble
Define sections, subsections, and roles exactly as in your real organization.
- Enable sections and subsections (Strings, Woodwinds, Brass…).
- Distinct roles: Owner, Administrators, Music direction, Musicians.
- Self-onboarding via invitation code, with optional approval.


Master the repertoire
Each work has its own record: title, composer, arranger, shared resources.
Detailed instrumentation (Concerto & Symphony)
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.
Organize rehearsals and concerts
Set the date, venue, and program. Relevant musicians are notified based on their assignment.
- Call lists by section from the Basic plan.
- Detailed call lists by subsection or instrument from the Suite plan.
- Optional automatic application of instrumentation to events (Concerto & Symphony).
When instrumentation is defined (Concerto & Symphony), the event can automatically reuse the required needs to generate the precise call list.


Required vs actual
Musicians are considered available by default. They declare unavailability from the event record.
- Visualization of declared unavailability for each event.
- Updating the actual staffing status.
Detailed Ensemble lineup analysis (Concerto & Symphony)
When instrumentation is defined:
- Comparing required musicians to those actually available.
- Identifying gaps by subsection.
- Targeted invitations for extras.
A unique architecture,
tailored to your scale.
From founding an ensemble to running a symphonic season, Arko evolves with you.
Structure and event organization form the foundation of our system, accessible from the very first steps. For ensembles that demand absolute rigor, advanced tiers unlock precision instrumentation and surgical staffing analysis.
Choose the level of precision that matches your ambition.
