Call 2021 represents a watershed between the old and the new Erasmus+ World. Starting from the new tool, the Beneficiary Module replacing the MT, to the change in the duration of Projects fixed at 26 months; to the beginning of the era of sustainability with the introduction of green travel, to short mobilities, to BIPs as an absolute innovation. * Saint Louis College of Music wanted to keep up with the change and the challenges of the new ECHE 2021-27 and measure itself with the new, in terms of implementing short mobilities, implementing BIPs, experimenting with green travel, distributing the mobility activity over several Calls. * In terms of partnerships, reliable long-term partners were confirmed and we opened up to new institutions with which we undertook a fruitful exchange pathway, as well as participating in an event of wide and prestigious international scope, the GLOMUS CAMP (https://www.glomus.net), a moment of confrontation and intercultural expressions between different Countries. * In quantitative terms, 37 out of 39 assigned mobilities were realised due to the cancellation of two STT due to flight cancellations, which were not eligible as CFM. * The demand for mobility is growing for all categories of participants.
