Now this is a very debatable topic. To answer this question, we must first define what a musical instrument is. Merriam-Webster defines “instrument” as “a device used to produce music.” With this definition, we need to also define what music is. Music is defined as “the science or art of ordering tones or sounds in succession, in combination, and in temporal relationships to produce a composition having unity and continuity.” Mayonnaise can be used to create this desired effect. It has a distinct sound when being scooped or placed. This sound can be made in repetition by the use of repetitive placement or use in a short period of time, defining it as percussive music. Because it can be used to create productive music, we can make the conclusion that mayonnaise is a device used to create music, which does define it as an instrument.
