Sorna

Sorna is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sorna rather than just read about it. In short: The sornā or sornāy (Persian: سُرنای، سُرنا, also سورنای، سورنا surnā, surnāy and also Zurna) is an ancient Iranian woodwind instrument. Etymology The word was most likely borrowed from an unknown Indo-European cognate of Luwian 𒍪𒌨𒉌 (zurni, “horn”), Sanskrit शृङ्ग (ṡṛṅga, “horn”), Latin cornū, and English horn, probably ultimately from Proto-Indo-European *ḱerh₂-.

Key takeaways

  • Sorna belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Sorna to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Sorna from memory before moving on to harder problems.

Reference excerpt

The sornā or sornāy (Persian: سُرنای، سُرنا, also سورنای، سورنا surnā, surnāy and also Zurna) is an ancient Iranian woodwind instrument.

Etymology The word was most likely borrowed from an unknown Indo-European cognate of Luwian 𒍪𒌨𒉌 (zurni, “horn”), Sanskrit शृङ्ग (ṡṛṅga, “horn”), Latin cornū, and English horn, probably ultimately from Proto-Indo-European *ḱerh₂-. A folk etymology explains that the word sorna is a Pahlavi derivative of sūrnāy (literally "strong flute"), which is a compand of 'sūr-' (strong) and '-nāy' (flute). According to such folk etymology, it was called "strong flute" due to its double-reed-construction rather than usual nāy (Persian: نای), which was made of a single tube of cane, while another folk etymology believes that the first part of word of sorna, is from sūr- again from Pahlavi and New-Persian, meaning the "banquet, meal and feast", thus the "banquet-flute". "Sorna", being a cognate of "Horn", can simply mean horn. This is a result of the Centum-Satem isogloss, and later Grimm's Law. Even in Persian there is another wind instrument whose name appears to be a cognate of both "Sorna" and "Horn", called "Karnā(y)" (کرنای/کرنا); this may stem from a re-borrowing from another language.

History 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 A small amount of air is forced under pressure through a small metal tube called the staple which serves to hold the reed and match it to the bore. This requires the player to make sure, as in oboe playing, that one also empties the lungs of stale air when taking a new breath. Often sornas were played in pairs, with a melody and a drone player. This drone may move to different notes during a piece of music, changing at prescribed places in the composition. Several other names, such as dohol, davul, tavel, and so on have been applied to the sorna. Since dohol is a double-faced drum sometimes it is called do-rūyeh in Persian language, in contrast to ghaval and daf, which are yek-rūyeh (one-faced).

Popularity The Sorna is mostly played in Loristan, Chaharmahal and Bakhtiari, Kurdistan, Sistan and Baluchestan Province and Iranian Azerbaijan. In Loristan, Sorna is used as a main instrument during wedding ceremonies and also funeral ceremonies (which is called Chamaryounah). Sorna almost always is accompanied with dohol in this region. In Balochistan It mostly performed by forming a circle by a group of people, dancing and clapping. Do-Chapi almost always includes Sorna and Dohol. In the region of Sistan and Baluchestan, sorna is mostly used in wedding ceremonies and other celebration. The instrument is always accompanied by dohol and sometimes may include traditional dance by forming a circle.

Worked examples

Example 1 — a first encounter with Sorna

Start with the simplest possible case. Write down what Sorna claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sorna before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sorna ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sorna

In research
Sorna appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Sorna in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Sorna is common in secondary-school and first-year university syllabi. It links to neighbouring topics Iranian inventions, Iranian musical instruments, Oboes, so understanding it makes those chapters shorter.
In everyday life
Look for Sorna outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Why does Sorna matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Sorna?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
