Between Music and Architecture Last night I went to an event at Madrid Architects Association Headquarters. It was organised by the Architecture and Music Work Group, and it was intended to be a dialogue between two women, one architect and another pianist and composer, talking about their respective disciplines. A friend and former teacher phoned me in the morning to invite me, but I had already registered to attend. It was that friend who presented the event, talking briefly about his relationship with the two women. The architect began the lecture telling an interesting story about the premiere of Luigi Nono´s Prometeo and the structure designed for the stage by Renzo Piano. After only two performances this structure was abandoned, neglected and during years it was considered to be lost, but further research led her to discover that it was in a little village near Milán, rescued by the major and waiting to be used again. The composer woman showed excerpts of her last work, combining electroacoustic music with that from tradicional instruments, as in her third string quartet, or applying the golden section and mathematics to give form to her compositions. As she talked we could listen to her beautiful music, contemporary but not as difficult as most of serial and stochastic works. But what most interested me was her reflections about how the space where the music is going to be performed affects some decisions to be taken during composition process. As I have said, it was supposed to be a dialogue between the two, but in fact it was more of a shared lecture, both women alternating their speechs. From this point of view it was a bit disappointing. Perhaps too long, lasting more than two hours, nevertheless it was an interesting and enjoyable evening.
