The first cycle for the development of the platform included a performance of Twenty Twenty - a new composition for MPO and chamber ensemble. The MPO consisted of approximately one hundred schoolchildren between ten- and twelve years old. Two research questions permeated this first cycle: 1. To what extent can the target group perform the musical material of Twenty Twenty as a MPO?, 2. What conclusions could be drawn based on the results and related to the three criteria: easy accessed, mobile and artistically rewarding?
