In musical terminology, what does 'sons bouches' mean?

'Son bouches' is a term that translates from French to 'stopped note' in musical terminology. This term is typically associated with brass instruments, where players use their hand to partially cover the bell of the instrument, producing a sound that is softer and more muted than the fully open tone. The effect created can imply a more subdued, less resonant quality, which distinguishes it from the brighter and fuller tones of instruments that are played without any obstruction.

In this context, the other choices do not accurately represent the meaning of 'sons bouches.' For instance, harmonic overtones refer to the series of frequencies that occur naturally when a note is played, but they do not directly relate to the idea of stopping a note. Muted sound, while somewhat similar in effect to a stopped note, does not specifically translate to the exact terminology used in 'sons bouches.' Quick passages refer to fast musical runs but are unrelated to the concept of stopping a note. Thus, the correct identification of 'sons bouches' as 'stopped note' is rooted in its specific function and application in musical performance.
