The Corona pandemic has affected orchestra organizations around the globe since January 2020. Most of the ensembles were forced to stop operations during hard lockdown periods of public life. Freelance ensembles and privately funded orchestras faced even higher pressure than state funded ones. The pandemic has shown, how fragile orchestras may be. On the other hand the pandemic has brought forth a boost of creative alternatives from single musicians, from greater ensembles and from orchestra managements to upkeep operations under new physically distanced conditions and on the internet. Highest flexibility was shown in artistic planning, in creating new programs, in digital and recording work, in outreach and education activities, in new concert formats or support of pandemic-related charity campaigns. The pandemic has shown, how agile orchestras might be. The very questions are: What are the lessons learned from the pandemic challenges? What are new structural approaches for musicians and managements to rethink orchestral organizations for the post-pandemic future? How can the engagement of musicians and staff for the own organization be enhanced? How can the ties towards the members of already familiar audience groups be strengthened? Every co-author of this book is a specialist in his or her field. Together we're looking out to all aspects from which we think that orchestral organizations should take a breeze of fresh air and rethink their operations in the "new normal" after the pandemic. There is no step back, there only are steps forward.
