traditional rotary valve operation Vs Thayer Valve operation
Traditional Rotary Valve Operation
Sound waves encounter sharp angles and severe changes of direction, producing complex turbulence and distortion.
The result is a weakened and stuffy note, loss of energy in the fundamental wave, increased resistance, and a change in tone and loss of clarity. Thayer Valve Operation Sound follows a smooth, undistorted path through the valve. It encounters no violation in path shape and imparts no acoustic penalty. The primary passage is identical in both open and operated positions. The result is clean performance, absolutely balanced in both modes.

Why choose Thayer?
Response
At a tempo of about one bar at 100, the trombonist needs a quick, sure response to play this passage. It does not take as long, nor is it as difficult to establish a note with the Thayer valve.

TONE
The Thayer valve makes this beautiful solo playable with no variation in balance and tone. It provides uniform performance whether in open or operated position.
Definition
The uncompromised fundamental sound wave allows a clear centering of the note on a given pitch. It gives a feeling of precision and control. Both the low and high ranges are outstanding in definition and clarity.

Dynamics
Maximum fortissimo passages are deliered full, round, and solid without the harsh flare of an overblown note. Feather light pianissimos speak with delicacy and assurance. All intensities are delivered with less effort as with the valve-less trombone.
