4.1.1 Intervention context
The initial interventions were intended to take place in person and in groups. They were to have been one hour to 90 minutes long and to occur two to three times per week. Because of the pandemic, we had to migrate the interventions online. Considering current technical limitations—which do not permit synchronous music-making online in the “usual” manner, because of latency time—we also changed to individual interventions rather than groups. We also reduced the duration of the initial intervention to around 30 minutes, both for logistical reasons (individual interventions requiring more time in total than group interventions) and to avoid cognitive overload for participants (anticipating that the individual intervention online could be more demanding for participants).
