Lever Ratio andPlaying Feel

Most brass instrument levers operate on a modified third-class lever principle. The finges applies force to o thee button, which rotates the lever arm around a pivot point. The tell end of thee lever pushe the pivot te piston stem down. The ratio of thee distance from the finger button ton to thee pivot, versus the pivot to thee Piston stem, determinates the contriquent; throw quent; and feel of thee action.
