What is the primary characteristic of the Dotted Crotchet?

The primary characteristic of a Dotted Crotchet is that it lasts for 1½ beats. This duration is derived from the basic value of a crotchet, which is 1 beat. When a dot is added to a note, it increases its length by half of its original value. Thus, in the case of a crotchet, the dot adds an additional half beat to the original 1 beat, resulting in a total of 1½ beats. This is an essential concept in music notation, as understanding the duration of notes allows musicians to interpret rhythms accurately in performance and composition.
