A whole note in music is a symbol that represents a note that lasts for a full four beats. While whole note is the usual term for this concept, there are some synonyms that can be used to describe it. Depending on the context and the musician's preferences, some other terms that may be used include semibreve, full note, or simply whole. These terms all essentially refer to the same type of note, but may be used to add variety to written music or to better convey the intended tone or tempo. Regardless of which term is chosen, the whole note remains an important foundational element in many musical pieces.
