Example: The music was composed by Hitoshi Sakimoto , who had also worked on the previous Valkyria Chronicles games . When he originally heard about the project , he thought it would be a light tone similar to other Valkyria Chronicles games , but found the themes much darker than expected . An early theme he designed around his original vision of the project was rejected . He redid the main theme about seven times through the music production due to this need to reassess the game . The main theme was initially recorded using orchestra , then Sakimoto removed elements such as the guitar and bass , then adjusted the theme using a synthesizer before redoing segments such as the guitar piece on their own before incorporating them into the theme . The rejected main theme was used as a hopeful tune that played during the game 's ending . The battle themes were designed around the concept of a  divorced from a fantasy scenario by using modern musical instruments , constructed to create a sense of atonality . While Sakimoto was most used to working with synthesized music , he felt that he needed to incorporate live instruments such as orchestra and guitar . The guitar was played by Mitsuhiro Ohta , who also arranged several of the later tracks . The game 's opening theme song ,  ( もしも君が願うのなら , Moshimo Kimi ga Negauno Nara ) , was sung by Japanese singer May 'n . Its theme was the reason soldiers fought , in particular their wish to protect what was precious to them rather than a sense of responsibility or duty . Its lyrics were written by Seiko Fujibayashi , who had worked on May 'n on previous singles . fill in the blank  : The music was composed by Hitoshi __________________ , who had also worked on the previous Valkyria Chronicles games

New input case for you: Commercial operations are remunerated activities which fall within the ICAO definition of CAT . Some are , however , closely aligned to , and considered part of , the GA sector . Public transport operations are non @-@ scheduled , on @-@ demand services flying between points specified by the customer , providing a more flexible service than airline travel . Air taxi operations offer charter services for third parties , and business or corporate aviation uses company @-@ owned aircraft to transport employees and clients . Aircraft used in these operations include business jets , helicopters , and twin piston @-@ engine aeroplanes carrying between six and ten people . An example of this type of operation is the transport by helicopter of spectators to the British Formula One grand prix at Silverstone . This involves so many flights that , according to Cranfield Aviation Services , on race day the heliport is temporarily the world 's busiest airport . Aerial work is a small but important component of the commercial GA sector , characterised in its simplest form as remunerated non @-@ transport activities , such as surveying , crop spraying , and emergency services work ( air ambulance and police ) .fill in the blank  :   Commercial operations are remunerated activities which __________________ within the ICAO definition of CAT .
