Common Questions About the Conn 36H

How does the Conn 36H differ from the Conn 34H alto trombone?

The Conn 36H adds a Bb attachment to the Eb alto trombone design, while the Conn 34H is the straight Eb version. The attachment gives the player alternate positions and added flexibility in passages where technical facility and slide reach matter.

What kind of player benefits most from an Eb/Bb alto trombone?

An Eb/Bb alto trombone is most useful for trombonists working in orchestral, chamber, and advanced ensemble settings where alto trombone parts are expected to have a distinct, compact tonal identity and precise response.

What does the .491/.500 dual bore contribute to the playing experience?

The .491/.500 dual bore design gives the 36H a focused alto trombone feel while allowing a touch of breadth through the slide. Players coming from tenor trombone often appreciate that balance when developing an alto concept.
