Hautbois - Sound

Sound

In comparison to other modern woodwind instruments, the oboe has a clear and penetrating voice. The Sprightly Companion, an instruction book published by Henry Playford in 1695, describes the oboe as "Majestical and Stately, and not much Inferior to the Trumpet." More humorously, the voice is described in the play Angels in America as sounding like that of a duck if the duck were a songbird. The timbre of the oboe is derived from the oboe's conical bore (as opposed to the generally cylindrical bore of flutes and clarinets). As a result, oboes are readily audible over other instruments in large ensembles.

Music for the oboe is written in concert pitch (i.e., it is not a transposing instrument), and the instrument has a soprano range. Orchestras frequently tune to a concert A (usually A440) played by the oboe. According to the League of American Orchestras, this is done because the pitch of the oboe is secure and its penetrating sound makes it ideal for tuning purposes. The pitch of the oboe is affected by the way in which the reed is made. The reed has a significant effect on the sound of the instrument. Variations in cane and other construction materials, the age of the reed, and differences in scrape and length will all affect the pitch of the instrument. German and French reeds, for instance, differ in many ways, causing the sound of the oboe to vary accordingly. Weather conditions such as temperature and humidity will also affect the pitch. Skilled oboists adjust their embouchure to compensate for these factors. Subtle manipulation of embouchure and air pressure allows the player to express timbre and dynamics.
