Which time signature is commonly used in Western music?

The time signature commonly used in Western music is 4/4. This signature indicates that there are four beats in each measure and that the quarter note receives one beat. It provides a balanced and stable rhythmic foundation, making it suitable for a wide variety of musical styles, including pop, classical, rock, and many others. The prevalence of 4/4 can be observed in countless songs and compositions throughout different genres, contributing to its familiarity and popularity among both musicians and listeners.

The other time signatures, while they may be used in certain contexts or specific genres, are not as universally adopted. For example, 5/4 is considered more unconventional and is often found in certain progressive or experimental music. Similarly, 7/8 is typically associated with specific folk or world music traditions and can create a complex and less stable rhythmic feel. The 2/3 time signature also doesn't fit the conventional framework of Western music, as it suggests a faster and less typical grouping of beats. Thus, while they all have their unique applications, they are not as commonly encountered in Western music as 4/4.
