[[Time signature]]s in Western [[musical notation]] traditionally are written in a form resembling fractions (for example: {{music|time|2|2}}, {{music|time|4|4}}, or {{music|time|6|8}}),{{r|jon-pea}} although the horizontal line of the musical staff that separates the top and bottom number is usually omitted when writing the signature separately from its staff. As fractions they are generally dyadic,{{r|libbey}} although [[Time signature#Irrational meters|non-dyadic time signatures]] have also been used.{{r|yanakiev}} The numeric value of the signature, interpreted as a fraction, describes the length of a measure as a fraction of a [[whole note]]. Its numerator describes the number of beats per measure, and the denominator describes the length of each beat.{{r|jon-pea|libbey}}
