African blackwood (Dalbergia Melanoxylon)
African blackwood is a worldwide best and proven timber for making any high end woodwind instruments such as Irish flutes, clarinets, Highland pipes, oboes, piccolos etc. The quality of this timber is far better than the popular in Bulgaria and Ester Europe Dryan wood (Cornus mas, European dogwood), which most of the kavals in Bulgaria are made from. African blackwood is known for its unique qualities, great strength and durability. It has average specific gravity of about 1.2, high natural oil content and it is extremely dense.The high content of natural oils makes this timber practically water proof.
Mopane (Colophospermum mopane)
The mopane tree only occurs in the far northern areas of southern Africa. It is a hard, heavy and oily timber that is termite resistant which makes it very useful as a construction material. Outside of Africa, mopane is increasingly being used for musical instruments, particularly woodwind, as suitable quality African blackwood has become harder to find. The tone is as rich as African Blackwood, as powerful, but warmer, resembling the tone of the Cocuswood. Its high density and good workability make it an attractive alternative to Blackwood.
