I recently posted that I am aiming for between 500 and 1000 hours of listening to my foreign languages in 2011.Some people suggested that it is difficult to listen that much. This caused me to reflect on when I have listened in a concentrated time for a long period. This is only possible occasionally. For example when driving from Munich to Porto in September I listened to 22 hours of the fabulous Portuguese Podcast Pessoal e Transmissivel, fascinating interviews broadcast over a period of several years. When I arrived in Portugal my Portuguese was at a new level. I have gardened for hours listening to Balzac, or Proust in French or driven for hours listening to I Promessi Sposi or La Provinciale by Moravia in Italian. I still remember myself cross country skiing for hours while listening to Turgenev or Bulgakov in Russian. When I am able to put together a listening marathon, by which I mean at least 4 hours of solid listening, while doing something else, I inevitably feel I have made a great step forward. The content must be interesting, at least 70% comprehensible, and the voice must be pleasing. I feel that I get pushed past a threshold and achieve a new connection with the language, one that I mostly keep. Try it some time.
