Bagatelle No 25 in A minor (WoO 59 and Bia 515) for solo piano, commonly known as Für Elise is one of Ludwig van Beethoven‘s most popular compositions. It was not published during his lifetime, only being discovered (by Ludwig Nohl) forty years after his death, and may be termed either a Bagatelle or an Albumblatt. The identity of “Elise” is unknown; researchers have suggested Therese Malfatti, Elisabeth Röckel or Elise Barensfeld. – Ivo Pogorelich
