I want to buy a Xun (an ancient flute from China). From what I have read, they are made of clay or ceramic. Image below from Wikipedia:

Xun

What is the difference between the two? Should that be a selection criterion? What other criteria should I be aware of?

  • Clay is ceramic. en.wikipedia.org/wiki/Ceramic – Tetsujin Aug 24 '16 at 13:39

    From your link "Frequently, the raw materials of modern ceramics do not include clays". It's called ceramic when baked at high temperature. – JSFDude Aug 24 '16 at 13:50

    I didn't say ceramic is clay, I said clay is ceramic. One is a sub-set of the other. – Tetsujin Aug 24 '16 at 14:02
  • @JSFDude "Ancient" flutes were not made from "modern" ceramic materials, most of which would be completely impractical for making musical instruments. – user19146 Aug 24 '16 at 22:04
  • Of course. The Xun is an ancient instrument, but I don't want to buy a 4000 years old flute. It's just that some Xun look really different. They seem to come in all sorts of shapes and materials. When you listen to Xun on youtube you can hear that the sound is not always the same. I also suspect that some of them are easier to use. For those reasons, I would like to have feedback from a specialist. – JSFDude Aug 25 '16 at 7:42

For starters, this site has a varying selection of the Xun. Prices ranging from $23 to $79 US. http://www.redmusicshop.com/Xun

From looking there, other criteria includes the hole count. From reading the wiki and other articles, the first Xun had only one hole but, I assume you don't want to go that traditional? :P The standards today are 8 hole and 10 hole Xuns; the 10 hole Xun also coming with the monikers, professional and concert-grade.

Be sure that the Xun, specifically, is what you are after.

Traditional Chinese musical instruments were classified into eight groups (bayin) according to their materials: gourd, earthenware, hide, wood, stone, bronze, silk and bamboo. It is said that there were more than 70 different musical instruments, but many of them have been lost or are obsolete today. https://en.wikipedia.org/wiki/Chinese_orchestra#The_ancient_Chinese_orchestra

So, it is only a Xun if it is made of earth. As Tetsujin mentions, clay is a form of earth from which ceramic can be made...

Interestingly:

Like all members of the ocarina family of wind instruments, its shape has almost no effect on its sound, which has lead to many different forms of the instrument. Some are spherical, while others are egg shaped, flattened or elliptical. Other have the form of a fish or a pear, which is the most popular today and resembles a modern ocarina. https://ocarinaforest.com/ocarinas/chinese-xun/

With this being the case, I speculate that it seems unlikely that the actual earth used to make the vessel would have any effect on the overall tone. You're looking at size and thickness for differences in tone; smaller for higher tones, larger for lower tones.

Also if anything in the composition of the instrument might effect the timbre, it's whether or not the earthenware has been glazed. The glazing itself may effect tone versus a non-glazed instrument. But, glazing is a delicate process in and of itself. Two Xuns of equal size and thickness may sound different due to their respective glazings alone...
