Which mute on brass instruments is associated with the wah-wah effect?

• A. Cup Mute
• B. Harmon Mute
• C. Straight Mute
• D. No Mute

Answer: (B)

The wah-wah effect on brass is produced by the Harmon mute. Its design creates a muffled, buzzy tone with a distinctive color that changes when you move the mute in and out or adjust your hand position around it, producing that vocal-like “wah-wah” quality heard in jazz solos. Other mutes alter tone in different ways—a cup mute gives a softer, dampened sound; a straight mute yields a bright, piercing timbre; playing without a mute offers an open, untreated brass tone. So the Harmon mute is the one most closely associated with the wah-wah effect.
