Piano Sonata No. 26 E flat major Op. 81a
Beethoven's Piano Sonata No. 26 in E-flat major, Op.81a, known as the Les Adieux sonata,
was written during the years 1809 and 1810. An average performance of the piece lasts about
17 minutes. The sonata is one of Beethoven's most challenging sonatas because of the mature
emotions that must be conveyed throughout it. It is also the bridge between his middle period
and his later period and is considered the third great sonata of the middle period.
