For being a Romantic work, Hummel's Rondo in Eb (op 11) felt very decidedly... classical. Although some elements of Romanticism were very clearly felt, overall, I struggled to hear the work 'stretching' classical form and convention to the point of needing to be classed as something different entirely.

Throughout my listening, I couldn't help but thinking 'Mozart,' both texturally, and in the way phrases are strung together. The sound is transparent and light in so many places, that it makes sense that Mozart would be an influence. A quick check of a Wiki on Hummel lists him as a pupil of Mozart.

That being said - the most notable elements of Romanticism that can be seen are an expansion of range and exploitation of the instrument that is very reminiscent of... Beethoven. Returning to the Wiki again establishes them as contemporaries and friends... if not slightly estranged. Hummel was asked to play at Beethoven's funeral, which he obliged... so respect obviously existed.

The best context, all things so far listed being considered, is that of an early guiding hand in the rise of Romanticism. His list of pupils and people who wished to study with him proves this to be quite possibly accurate: Mendellsohn, Liszt, and others all appear as his pupils or those that would have but couldn't for one reason or another.

This is not to say that his later works are not more 'Romantic' than this particular work. I wouldn't know, to be perfectly frank. More research could... potentially... be done... but... with other works to study, perhaps another time. Suffice it to say that the work that we did listen to was likeable... if not nescessarily the most Romantic work ever.
