The term "scale of C Major" is often used in music theory to describe a specific set of notes arranged in ascending or descending order. This scale is one of the most common scales in Western music and is often used as a starting point for many beginner musicians. However, there are many synonyms that can be used to describe the same thing, including the C Major scale, the Ionian mode, or simply the white keys on a piano. Regardless of what it's called, the scale of C Major is an important building block in music theory and a useful tool for any musician to have in their repertoire.
