Contra Forte

The contraforte is a proprietary instrument with a range similar to the contrabassoon produced by Benedikt Eppelsheim and Guntram Wolf. It is intended to have improved dynamics and intonation over the distinctive but sometimes reticent sound of the conventional contrabassoon. The contraforte uses a different and wider bore than the contrabassoon to produce a distinct tone; the sound is more even in strength and intonation across registers, remaining quite strong into the high register, unlike a contrabassoon.

It also lacks the distinct "rattle" of a contrabassoon, although appropriate reed design can replicate this effect where desired. Wolf and Eppelsheim developed an accurate bore taper and precise keyworks in order to simplify fingerings in spite of the instrument's large size.

In October 2010 Lewis Lipnick, contrabassoonist for the National Symphony Orchestra in Washington, DC, played it in a performance of Beethoven's Symphony No. 9. According to Lipnick, the other members of the orchestra, who used to make jokes about the sound of his old contrabassoon, praised the sound of the contraforte.
