Information:  - The trombone is a musical instrument in the brass family. Like all brass instruments, sound is produced when the player's vibrating lips (embouchure) cause the air column inside the instrument to vibrate. Nearly all trombones have a telescoping slide mechanism that varies the length of the instrument to change the pitch. Many modern trombone models also utilize a rotary valve as a means to lower pitch of the instrument. Variants such as the valve trombone and superbone have three valves like those on the trumpet.  - A trumpet is a musical instrument commonly used in classical and jazz ensembles. The trumpet group contains the instruments with the highest register in the brass family. Trumpet-like instruments have historically been used as signaling devices in battle or hunting, with examples dating back to at least 1500 BC; they began to be used as musical instruments only in the late-14th or early 15th century. Trumpets are used in art music styles, for instance in orchestras, concert bands, and jazz ensembles, as well as in popular music. They are played by blowing air through almost-closed lips (called the player's embouchure), producing a "buzzing" sound that starts a standing wave vibration in the air column inside the instrument. Since the late 15th century they have primarily been constructed of brass tubing, usually bent twice into a rounded rectangular shape.   - Don Lang ( born Gordon Langhorn , 19 January 1925 -- 3 August 1992 ) was an English trombone player and singer , who led his own band , Don Lang & his Frantic Five .  - The embouchure is the use of facial muscles and the shaping of the lips to the mouthpiece of woodwind instruments or the mouthpiece of the brass instruments. The word is of French origin and is related to the root "bouche" (fr.), 'mouth'. The proper embouchure allows the instrumentalist to play the instrument at its full range with a full, clear tone and without strain or damage to one's muscles.  - A brass instrument is a musical instrument that produces sound by sympathetic vibration of air in a tubular resonator in sympathy with the vibration of the player's lips. Brass instruments are also called "labrosones", literally meaning "lip-vibrated instruments".    Given the paragraphs above, decide what entity has the relation 'genre' with 'jazz'.
