Johann Nepomuk Hummel (1778-1837) is a fascinating case history; a composer trapped in a no man's land between the classical and romantic ages.
His works offer glimpses of the new musical worlds that the slightly older Beethoven unlocked but, too often, they wilt under the weight of formulaic doodling with scales and arpeggios.
In 1823-24 Hummel, a former pupil of Mozart, made whittled-down arrangements of his teacher's symphonies and the English publication of them was popular enough to be pirated over the channel.
No doubt they met a ready market in middle-class parlours with symphonic ambitions, able to accommodate a quartet of flute, violin, cello and piano.
Uwe Grodd has painstakingly edited the original scores, describing them as "very good prints, but with 700 to 800 mistakes".
