Contempora Single-Valve Bass Trombones

Allen Ostrander | "I am using the Reynolds Contempora Philharmonic model Bass Trombone exclusively because I think it is superior to any other trombone in the following ways: The tone has more carrying power and projects better in all registers and in all dynamics without loss of quality. The response is the fastest which makes short loud notes much easier to play. The only easy blowing trombone that I have found which will still retain tone in fortissimo. It is the best in tune of any instrument that I have ever used. The low register is exceptionally good and is the best I have ever found."

In 1949, Reynolds introduced the Contempora model line and rebranded the Reynolds bass trombone as the Contempora "Symphony" model. The familiar bronze bell, covered with a tinted lacquer that gave the horn the nickname "The Tangerine Trombone", was introduced in the early or mid 1950s.

In the early 1950s, Reynolds began working with Kauko Kahila (St. Louis Symphony, 1944-1952; Boston Symphony Orchestra, 1952-1972) on more effective ways of extending the low-register range of the bass trombone and enable more accurate playing of passages such as the low B glissando in Bartok's "Concerto for Orchestra".

Reynolds updated the Contempora bass trombone in the mid-1950s with a modified closed wrap that had two tuning slides: the main F tuning slide and a second slide that could pulled to achieve E tuning, then pushed in to return to F. This was an advantage over the older design with a single tuning slide, but still required a player to manually adjust tuning slides while playing – a problem ultimately solved later with the addition of a second rotary valve that enabled the E tuning only when needed.
