La Central, one of the best bookshops in Barcelona, organizes every season, a series of short courses on literature and, recently, also about music. During their Winter Academy, I gave a course on Lied, for seven weeks (fourteen hours), covering very briefly from pre-schubertian to post-straussian Lieder, a course that ended one month ago. I greatly enjoy giving those courses, and this one wasn't an exception. So, my first reason to write this post is to show my gratitude to all participants. Thank you for your trust, your contributions, your curiosity your good mood... Thank you very much indeed!
