What is the duration of a Dotted Quaver?

A dotted quaver is a note that combines the duration of a quaver (or eighth note) with an added half of its own value. A quaver lasts for half a beat, and therefore, when you add a dot to it, you extend its length by another quarter of a beat (which is half of a quaver).

So, the calculation for the duration of a dotted quaver would be:

1. Duration of a quaver = ½ beat
2. Add half of that duration (which is a quaver’s value) = ½ beat + ¼ beat = ¾ beats.

This calculation illustrates that the dotted quaver lasts for three-quarters of a beat. The answer provided reflects this understanding accurately.
