Detailed Description

Time signatures are represented by two elements. The beats element indicates the number of beats, as found in the numerator of a time signature. The beat-type element indicates the beat unit, as found in the denominator of a time signature. The symbol attribute is used to indicate another notation beyond a fraction: the common and cut time symbols, as well as a single number with an implied denominator. Normal (a fraction) is the implied symbol type if none is specified. Multiple pairs of beat and beat-type elements are used for composite time signatures with multiple denominators, such as 2/4 + 3/8. A composite such as 3+2/8 requires only one beat/beat-type pair. A senza-misura element explicitly indicates that no time signature is present.
The MusicXML time element is defined in attributes.dtd.
