Respighi incorporated our little feathered friends into his music and was the first to do it this way. He wrote a piece called "The Pines of Rome" in the early middle twenties and wanted to incorporate a bird (Nightingale) songs and chirping into the third movement (played below). No instrument could, of course, replicate the actual sound so he designated (in the musical score) a recording (an actual 78rpm) to be played near the end while the orchestra is playing. This was the first time that an electronic device was used in an orchestra score - the theremin (science fiction sound) coming some 3 years later. Thus armed with knowledge you can face your day.
