+/**
+ * For a more accurate description of the tempo of a musical piece, the
+ * <i>Synchronised tempo codes</i> frame might be used.
+ * 
+ * The tempo data consists of one or more tempo codes. Each tempo code consists
+ * of one tempo part and one time part. The tempo is in BPM described with one
+ * or two bytes. If the first byte has the value $FF, one more byte follows,
+ * which is added to the first giving a range from 2 - 510 BPM, since $00 and
+ * $01 is reserved. $00 is used to describe a beat-free time period, which is
+ * not the same as a music-free time period. $01 is used to indicate one single
+ * beat-stroke followed by a beat-free period.
+ *
+ * The tempo descriptor is followed by a time stamp. Every time the tempo in the
+ * music changes, a tempo descriptor may indicate this for the player. All tempo
+ * descriptors must be sorted in chronological order. The first beat-stroke in
+ * a time-period is at the same time as the beat description occurs. There may
+ * only be one SYTC frame in each tag.
