Given the following context:

On Bennett's return to London he took up a teaching post at the RAM which he held until 1858. During his second long stay in Germany, from October 1838 to March 1839, he played his Fourth Piano Concerto (Op. 19, in F minor) and the Wood Nymphs Overture, Op. 20. Returning to England, he wrote to his Leipzig publisher Friedrich Kistner in 1840, bemoaning the difference between England and Germany (and hoping that a German would redress the situation): You know what a dreadful place England is for music; and in London I have nobody who I can talk to about such things, all the people are mad with [Sigismond] Thalberg and [Johann] Strauss [I], and I have not heard a single Symphony or Overture in one concert since last June. I sincerely hope that Prince Albert ... will do something to improve our taste.
On Bennett's third trip, from January to March 1842, in which he also visited Kassel, Dresden and Berlin, he played his Caprice for piano and orchestra, Op. 22, in Leipzig. Despite his then-pessimistic view of music in England, Bennett missed his chance to establish himself in Germany. The musicologist Nicholas Temperley writes One might guess that the early loss of both parents produced in Bennett an exceptionally intense need for reassurance and encouragement. England could not provide this for a native composer in his time. He found it temporarily in German musical circles; yet, when the opportunity came to claim his earned place as a leader in German music, he was not quite bold enough to grasp it.
