Trombone with F attachment slide position second harmonics. [18] Modern trombones often have a valve attachment, an extra loop of tubing attached to the bell section and engaged by a valve operated by the left hand by means of a lever or trigger. The valve attachment aids in increasing the lower range of the instrument, while also allowing ...
Three-valve instruments and trombones without valves have seven possible configurations or positions. Four-valve instruments, tenor trombones with F attachments and bass trombones (potentially with multiple valves) are more complicated. The extra length of tubing utilized when instruments are extended by nearly half their length throws off the ...
Thayer axial flow valve on a tenor trombone. The axial flow valve, or Thayer valve, is a brass instrument valve design patented in 1978 by Orla Ed Thayer. [1] Designed with assistance from Zigmant Kanstul, it was originally intended to replace the traditional rotary valve on the French horn, but instead revolutionized the design of trombone valve attachments.

Hagmann valve on a tenor trombone. The Hagmann Free-Flow Valve is a trademarked brass instrument valve design developed by Swiss musician and instrument technician René Hagmann, first introduced for trombone F attachments in 1990.
Trombone F attachment valves are usually rotary, with several variations on the basic design also in use, such as the Thayer axial flow valve and the Hagmann valve. Rotary valve was first applied to the horn in 1824 by Nathan Adams (1783–1864) of Boston and patented in 1835 by Joseph Riedl. [5] Tuba with 4 rotary valves, by Yamaha
The Superbone can be played as a slide trombone, a valve trombone, or in combination. Using the slide and valves in combination requires the slide positions to be adjusted, just as when using the trigger of an F attachment on a tenor or bass trombone. Using the slide with the first and third valves engaged has the same effect as using an F ...

The first of these types was the Stölzel valve, bearing the name of its inventor Heinrich Stölzel, who first applied these valves to the French horn in 1814. Until that point, there had been no successful valve design, and horn players had to stop off the bell of the instrument, greatly compromising tone quality to achieve a partial chromatic scale.
