Time Signatures - TSV

Time signatures are fractional symbols placed at the beginning of musical notation, where the numerator indicates beats per measure and the denominator indicates which note value receives one beat. They are broadly classified into simple meters (2/4, 3/4, 4/4, etc.) and compound meters (6/8, 9/8, 12/8, etc.), each with distinct rhythmic feels and accent patterns. As one of the most fundamental elements in Western music theory, time signatures determine the interpretation of tempo and rhythm in performance.
