The term "tenth" refers to the ordinal number that indicates the position of something in a sequence, specifically the one that comes after the ninth. In mathematics, it can also represent a fraction, where one part is divided into ten equal parts, denoted as 1/10. This concept is commonly used in various contexts, such as measuring, ranking, and organizing items. In music, "tenth" can refer to an interval that spans ten diatonic scale degrees. For example, in the C major scale, the interval from C to E is considered a tenth when counting the notes. Understanding the concept of "tenth" is essential in both mathematics and music theory.
