And since the pedal was strictly for his own, largely extemporaneous, use there would be no reason to write out notes. Louis Schone made a pedalflügel for Robert Schumann in 1843, when he was in Dresden. Schumann preferred an upright pedal piano, and his pedal keyboard had 29 notes and was connected with an action placed at the back of the piano where a special soundboard, covered with 29 strings, was built into the case. Schumann wrote much music for the pedal piano and was so enthusiastic about the instrument that he convinced Felix Mendelssohn, who owned a grand pedal piano, to form a class devoted to it in the Leipzig Conservatory. Charles-Valentin Alkan owned an Erard pedal piano made in 1853 and now in the Musée de la Musique, the historic instrument collection of the Conservatoire de Paris. Alkan composed a number of works for it, in the virtuoso style to be found in his other piano music. Kevin Bowyer has revived some of this music in recent years, though he plays it on the organ. The instrument never became very popular in the 1900s, and it remains a rarity. It is mostly used to enable organists to practice at home, rather like the pedal harpsichord and clavichord were centuries ago, instead of being used to play the pedal piano repertoire. In the 2000s, pedal pianos are made in Italy by Luigi Borgato (who reinvented and patented it). This company makes the Doppio Borgato, an independent bass-register instrument connected to a pedal board, on which a concert grand can be placed. Borgato expanded the register of the bass piano to 37 notes, A0 to A3 (rather than the standard 30 or 32 on an organ). On September 13, 2011 Italian pianist Roberto Prosseda presented the modern premiere of the Concerto for pedal piano and orchestra by Charles Gounod with Orchestra Arturo Toscanini conducted by Jan Latham Koenig. On April 27, 2012, the Pinchi Pedalpiano System, designed by Claudio Pinchi and Roberto Prosseda, and built by the organ building enterprise Fratelli Pinchi Ars Organi, was presented in a public performance by Roberto Prosseda. It is a pedalboard which works with any two standard 88-key grand pianos. The Pinchi pedalboard has 37 pedals (from A to A three octaves up) but the Pinchi Pedalpiano System has a total range of five octaves, thanks to 61 wooden "fingers", as can be seen
