MUSICASA Cassetti Sonori (Sound Drawers) is a project that stems from the need to offer online educational activity regarding music in a particular context such as the lockdown linked to the Covid-19 national health emergency. The Music and Multimedia Laboratory "Disaccordi” of the Artistic High School "G.C.Argan" in Rome, founded and coordinated by prof. Antonio Buldini, has in fact launched a completely online activity, with the aim of stimulating and developing the skills of listening and production. The experience is mainly aimed at upper secondary school students but, with appropriate remodeling, it can also be adopted in primary and lower secondary (middle) schools. The health crisis led to a multimedia workshop project, in pursuit of online activity that favoured sound expression and communication. The basic aims of the project were: 1. Creation and use of an online space for meetings, discussion and sharing of ideas/materials; 2. Testimonial, memory and introspective sound research; 3. Music processing with creation of a digital sound book. In this way, the children listened to and collected the sounds, noises, and soundscape of domestic environments; while also using the reflection and introspective research from the period they experienced in the implementation of musical activity, performances, recordings and audio editing. All these productions were then placed in "sound drawers", true containers arranged within a digital book, constituting a sort of archive of the particular space-time dimension they experienced and the educational activities carried out.
