Alto Trombone Bells

Alto Trombone BellEdwards alto trombones are available in 7¾" bell flares in the following wall thicknesses: 22 (heavier) and 23 (lighter) gauges. Bells are available in yellow brass (70% copper 30% zinc) and red brass (90% copper 10% zinc). Higher copper content bells generally are very dark in the soft volumes but become more brilliant in the louder volumes. Yellow brass bells are more consistent in timbre throughout all registers and dynamics.

A soldered bell tends to have a very centered sound with a lot of core (fundamental). The articulations are slightly dampened and softer with the solder, while the sound is more direct and compact.

An unsoldered bell has a very wide sound with more overtones. Articulations are easier with an unsoldered rim. More near feel is apparent with these bells as the sound is wider, which helps give the player more feedback.

Tempering occurs when a bell is spun twice on a mandrel which work hardens the bell. This adds brilliance and colour to the sound.

Double buffing thins the bell slightly. It actually creates a thickness in between any two gauges.

Heat treating is a baking of the entire bell. This softens the metal immensely and creates a very dark sound. This works best on heavier bells as it tends to free them up. Heat treating is not recommended on thinner bells as it makes them more prone to mute dents. The CF treatment has virtually replaced heat treating.

CF treating is a partial heat treating process. This treatment allows the bell to blow more freely and adds colour to the sound.

In Their Own Words

David Perkel

"I have been playing Edwards trombones in orchestras, solo recitals, chamber ensembles, jazz ensembles, and commercial settings for almost twenty years. These instruments allow me to get the sound I desire, are free-blowing, and they have such amazing evenness in all registers. They are, without a doubt, the best trombones I have ever played. Working with Christan to find the best orchestral and jazz horns for me has always been a fantastic experience! He is extremely knowledgeable about each model and has always helped select the horns that suited me best."
