Johann Nepomuk Hummel was a noted Austrian composer and piano virtuoso who not only wrote substantially for the instrument, but also transcribed a series of important orchestral pieces. Among them are two transcriptions of Beethoven’s Symphony No. 2 in D Major, Op. 36- the first a version for piano solo and the second a work for piano quartet, with flute substituting for the traditional viola part. This study will examine Hummel’s treatment of the symphony in both transcriptions, looking at a variety of pianistic devices in the solo piano version and his particular instrumentation choices in the quartet version. Each of these transcriptions can serve a particular purpose for performers. The solo piano version is an obvious virtuoso vehicle, whereas the quartet version can be a refreshing program alternative in a piano quartet concert.
