Which mute is described as producing a muffled, darker tone and was common in the trumpet big band era of the 1930s and 40s?

• A. Straight mute
• B. Cup mute
• C. Bucket mute
• D. Wah-wah mute

Answer: (B)

The effect being tested is how a mute changes the trumpet’s tone color. A cup mute softens the trumpet’s brightness and adds a mellow, darker, more muffled quality, which was a common color for trumpet lines in big-band records of the 1930s and ’40s. The mute works by dampening high frequencies and shaping the sound envelope, helping the trumpet blend with the rhythm and reed sections while still singing through the band. The other mutes produce different sounds: a straight mute brightens and cuts through with a harsher, more piercing edge; a bucket mute is far more muffled and damped, often used for special effects or darker textures in a more extreme way; the wah-wah mute creates a vocal-like pitch modulation rather than a simple muffled tone. So, the cup mute best fits the description.
