The wah-wah mute (aka Harmon) produces which type of tone?

• A. Bright, piercing tone
• B. Buzzed tone
• C. Soft, muffled tone
• D. Pure, clear tone

Answer: (B)

Muting devices on brass instruments reshape how the air column vibrates, changing the tone by altering the harmonic content. The Harmon (wah-wah) mute is designed to partially block the mouthpiece and alter the air flow in a way that tightens and stresses certain harmonics, producing a distinctive buzzing, nasal quality. That buzzy character is what gives the wah-wah mute its recognizable sound, often described as a buzzed or buzzy timbre with the classic wah-wah effect. A bright, piercing tone comes from a clean, unmuffled or straight-muted sound, a soft, muffled tone from a cup mute, and a pure, clear tone from an open or minimally muted instrument. So the best description for the Harmon mute is a buzzed tone.
