Which term is described as 'with a mute'?

• A. Tremolo
• B. Slur
• C. Simile
• D. Tie

Answer: (A)

The phrase “with a mute” is a directive to change the instrument’s timbre by using a mute, typically written as con sordino (often abbreviated sord. or con sord.). Tremolo, the option listed first, is about rapid repetition of a note or between two notes and is a technique applied for texture or speed, not about muting. A slur indicates that notes should be played legato, connecting them smoothly. Simile means you should continue the same manner as in the previous passage. A tie connects two notes of the same pitch across a barline. So, the idea of playing “with a mute” is not conveyed by any of these terms; the correct designation for the mute itself would be con sordino, which isn’t listed among the choices.
