  Between 1815 and 1819, Beethoven's output dropped again to a level unique in his mature life. He attributed part of this to a lengthy illness that he called an inflammatory fever that he had for more than a year starting in October 1816. Solomon suggests it is also doubtless a consequence of the ongoing legal problems concerning his nephew Karl, and of Beethoven finding himself increasingly at odds with current musical trends. Unsympathetic to developments in German romanticism that featured the supernatural (as in operas by Spohr, Heinrich Marschner and Carl Maria von Weber), he also "resisted the impending Romantic fragmentation of the... cyclic forms of the Classical era into small forms and lyric mood pieces" and turned towards study of Bach, Handel and Palestrina. An old connection was renewed in 1817 when Maelzel sought, and obtained, Beethoven's endorsement for his newly developed metronome. During these years the few major works he completed include the 1818 Hammerklavier Sonata (Sonata No. 29 in B-flat major, Op. 106) and his settings of poems by Alois Jeitteles, An die ferne Geliebte Op. 98 (1816), which introduced the song cycle into classical repertoire. In 1818 he began musical sketches that eventually formed part of his Ninth Symphony.
  
  By early 1818 Beethoven's health had improved, and his nephew Karl, now aged 11, moved in with him in January (although within a year Karl's mother had won him back in the courts). By now Beethoven's hearing had again seriously deteriorated, necessitating that he and his interlocutors write in notebooks to carry out conversations. These 'conversation books' are a rich written resource for his life from this period onward. They contain discussions about music, business, and personal life; they are also a valuable source for his contacts and for investigations into how he intended his music should be performed, and of his opinions of the art of music. His household management had also improved somewhat with the help of Nannette Streicher. A proprietor of the Stein piano workshop and a personal friend, Streicher had assisted in Beethoven's care during his illness; she continued to provide some support, and in her he finally found a skilled cook. A testimonial to the esteem in which Beethoven was held in England was the presentation to him in this year by Thomas Broadwood, the proprietor of the company, of a Broadwood piano, for which Beethoven expressed thanks. He was not well enough, however, to carry out a visit to London that year which had been proposed by the Philharmonic Society.
