In the first "Theory Essentials 101" lesson we take a look at the "lingo" behind Intervals which are used to describe chords, scales, modes etc. Intervals are the basic building blocks anything is built upon when communicating harmonic music.
Forgot to mention Augmented is also called "Sharp", and referred to with a "#" as opposed to flat which is "b". Example, aug11 will be spelled "#11".
Hope you enjoyed this, please leave a comment below if you have suggestions of topics to cover in the future.
