Rhythm is a Language
Rhythm notation is a “universal language” used world-wide.
I promised Q that I would tell you why I am called Cal.
There are a few reasons for my name. You probably noticed I have buttons that have lots of different music symbols written on them, so – I am a Rhythm Calculator. 

Rhythm Notation requires knowing how to count and why Q said that he could always count on me.

As Cal the Rhythm Calculator, my quest is to teach you how these measurements are calculated, and to help you learn the fundamentals of Rhythm Notation.

Exact measurements are needed in order to define all types of note duration.
