The instrument's history dates back to the
Achaemenid Dynasty (550–330 BCE), and was used to play at the end of the day from the city gate or from the local administration building. This custom persisted in
England until the 19th century, the
town waits playing
shawms to mark the hours. The instrument was mainly played in outdoors in regional music of
Iran in the festive ceremonies (the Persian poet
Molana Rumi mentioned the sorna and dohol in his poems). The Achaemenid sorna was a large trumpet-like instrument, but in later dates was reduced in size, and became more shrill like the
oboe, or
dozale (double oboe), which is characterized by a turned wood body of simple shape, with a heavily flared bell. The earlier was categorized as a
trumpet, but this was a mistaken idea based on the bell of the oboe and the freeblowing embouchure that often gives a superficial resemblance to a
brass embouchure, particularly if the oboe is fitted as so many are with a lip ring. According to the
Shahnameh, it was King
Jamshid who devised the Sornā. Except the literary evidences, there are also number of artefacts from
Sasanian dynasty (224–651 CE), depicting Sorna, such a silver dish, currently in
Hermitage Museum. ==Function==
