What defines a virtuoso in music?

A virtuoso in music is primarily defined as an instrumentalist or singer who possesses extraordinary technical skill. This designation emphasizes not just proficiency, but exceptional talent and the ability to perform music with remarkable dexterity, precision, and artistry. Virtuosos often showcase their skills through complex pieces that require a high level of technical execution, impressing audiences with their command of their instrument or their vocal range.

In contrast, while a composer known for innovative styles can certainly be celebrated and revered in the field of music, the term "virtuoso" specifically pertains to performers rather than creators. Conductors, although vital to the music-making process, are focused on interpretation and direction rather than performance skills on a specific instrument or voice. Similarly, a musicologist's role involves the scholarly study of music history, theory, and styles, which does not align with the technical performance aspect associated with being a virtuoso. Thus, the definition centered on technical skill directly relates to why this option accurately encapsulates what constitutes a virtuoso.
