Continuous pitch instruments

The trombone is a musical instrument in the brass family. As with all brass instruments, sound is produced when the player's lips vibrate inside a mouthpiece, causing the air column inside the instrument to vibrate. Nearly all trombones use a telescoping slide mechanism to alter the pitch instead of the valves used by other brass instruments. The valve trombone is an exception, using three valves similar to those on a trumpet, and the superbone has valves and a slide.

The timpani (; ) or kettledrums (also informally called timps) are musical instruments in the percussion family. A type of drum categorised as a hemispherical drum, they consist of a membrane called a head stretched over a large bowl traditionally made of copper. Thus timpani are an example of kettledrums, also known as vessel drums and semispherical drums, whose body is similar to a section of a sphere whose cut conforms the head. Most modern timpani are pedal timpani and can be tuned quickly and accurately to specific pitches by skilled players through the use of a movable foot-pedal. They a

The oud ( ; , ) is a Middle Eastern short-neck lute-type, pear-shaped, fretless stringed instrument (a chordophone in the Hornbostel–Sachs classification of instruments), usually with 11 strings grouped in six courses, but some models have five or seven courses, with 10 or 13 strings respectively.

The theremin (; originally known as the ætherphone, etherphone, thereminophone or termenvox/thereminvox) is an electronic musical instrument controlled without physical contact by the performer (who is known as a thereminist). It is named after its inventor, Leon Theremin, who patented the device in 1928.

A sackbut is an early form of the trombone used during the Renaissance and Baroque eras. A sackbut has the characteristic telescopic slide of a trombone, used to vary the length of the tube to change pitch, but is distinct from later trombones by its smaller, more cylindrically-proportioned bore, and its less-flared bell. Unlike the earlier slide trumpet from which it evolved, the sackbut possesses a U-shaped slide with two pa

The buccin, or buccin à tête de serpent, is a visually distinctive trombone popularized in military bands in France between 1810 and 1845 which subsequently faded into obscurity. It should not be confused with another instrument also called "buccin", revived in France in 1791 and modeled after the ancient Roman buccina which could deliver only four distinct notes.

The Electro-Theremin is an electronic musical instrument developed by trombonist Paul Tanner and amateur inventor Bob Whitsell in the late 1950s to produce a sound to mimic that of the theremin.It was also known as the "Tannerlin." The instrument features a tone and portamento similar to that of the theremin, but with a different control mechanism. It consisted of a sine wave generator with a knob that controlled the pitch, placed inside a wooden box. The pitch knob was attached to a slider on the outside of the box with some string. The player would move the slider, thus turning the knob to t
