The term "5th" typically refers to the ordinal number that indicates the position of something in a sequence, specifically the one that comes after the fourth. It is commonly used in various contexts, such as ranking, dates, and events. For example, the 5th of July is the day that follows the 4th of July. In music, "5th" can also refer to the interval between two notes. A perfect fifth is a specific distance between notes that is often used in harmony and chord construction. For instance, in the C major scale, the note G is the perfect fifth above C.
