Woodwind instruments can and have been made out of many different materials. Historically, the first instruments were made out of box-wood or other European hardwoods like apple-, pare- or plum wood. To be suitable for woodwind instruments, it needs to be hard and stable, to keep in shape as well as withstand the constant exposure of high humidity, produced inside the instruments bore.
From the middle of the 1900 century, tropical woods -like ebony and African blackwood/Mpingo- became the preferred material, do to its superior qualities regarding sound and stability. Mpingo is one of the hardest and densest wood available. It grown in the savannas and bushes in eastern Africa (Kenia, Tanzania and Mozambique). Mpingo needs at least 80 years before the tree is large enough to get harvested. Some of them are as old as 300 years. Nobody thought about clarinets that many years ago. Since 2016 Mpingo is listed on the Cites list of endangered species and it is now under special protection.
In 2015 Michele von Haugg founded Dajara - Clarinets for Conservation- to create an awareness for the important s of mpingo for the music world. Besides free music lessons in Tanzania, they started to plant over 2000 Mpingo trees in dedicated areas to ensure that later generations can appreciate this amazing wood as well.
The center of Grenadill is brown to black, the outer splint is white .
Cocobolo is another occasionally used tropical wood-primarily for student instruments and bells. It is less dense and less expensive. To resemble mpingo/grenadillo it is often stained black.
To reduce the price of the instrument, some builders choose to use cocobolo for the bell and stain it black. .
Green-line , a mpingo/grenadill compound material made from mpingo dust, Carbone fiber and glue was developed to be able to preserve more trees as well as to prevent instruments from cracking. It is solemnly used by Buffet Crampon. The acoustic and physical properties are of the same high quality like grown wood. Cracks are extremely unlikely but body tenons have a higher risk of braking. Thats why Lohff & Pfeiffer offers a special Greenline tenon enforcement .
This special metal enhancement reduces the risk of breaking a Greenline tenon .
Besides wood, other materials have been used as well.:
Greenline tenons break easily, do to the lack of a grown structure.. . Metal clarinets have been made by all mayor manufactories from around the turn of the century until the early 40th. They were very popular among doubles during the Big-band and Swing-Music area. Their sound can be surprisingly warm and round. We carry always some vintage as well as Orsi Metal clarinets. Orsi is the only modern manufacturer, who still produces them.
Different types of plastic as well as the heavier hard-rubber is used since the 1960 for student instruments. They require less care and are considerably cheaper. Although most of them are made out of black ABS or Nylon, you might find some clear ones made out of Acryl.
