A sixteenth note is half as long as an note.

The clarification "half as long as an note" seems to be incomplete. Could you please provide more information?

A sixteenth note is actually a quarter of the duration of a regular note. Let's break it down step by step:

1. A regular note, also known as a quarter note, is typically given one beat in common time (4/4 time signature). It represents a length of time that is equal to one quarter of the measure.

2. A sixteenth note, on the other hand, is four times shorter than a quarter note. This means that within the same measure, four sixteenth notes can fit in the space of one quarter note.

To summarize, a sixteenth note is a quarter of the duration of a regular note, not half as long as a note.
