There is no clear record of the exact date composer Beethoven was born but there is a record of his baptism on December 17th 1770, in Bonn so it's understood he was born the day before. A preview on Friday of the renovated Beethoven House Museum in his native city Bonn offered a glimpse of the festivities planned ahead of the big day next year. April 25th and 26th: Berlin hosts a 24-hour "Beethoven Marathon" by the city's Philharmonic orchestra. April 28th: Back in Bonn, a hypothetical version of Beethoven's unfinished Tenth Symphony completed by artificial intelligence is to be performed. May 16th: Kraftwerk gives an open-air concert in Bonn in honour of Beethoven.
