So tenants can try and be considerate to each other with the times they can practice.
Have an online weekly schedule, where people who practice musical instruments can fill in how many hours they want to practice every week, and all the times they can practice day by day, hour by hour for a typical week. At the same time, other tenants can fill in times they absolutely have to have peace and quiet. This will make it easier to find practice times (if the tenants are considerate, to begin with.)
