The vocabulary used in music is quite confusing. Even the definition of some of these terms can be sometimes difficult to understand. It's as if music was reserved to a special private club that limits its members by making their language way more confusing than it should be.

The object of this article is to demystify the subject by offering a list of definitions of the most commonly used terms associated with music theory. In the following list, I will try to use every day words and eliminate all the extra wordy baggage often associated with music.

Because this list is meant to bring the reader up to date quickly, the following definitions are greatly simplified and may even be considered wrong by more advanced musicians. The real purpose of this article is to help beginners understand what is being talked about when surrounded by more advanced (or wordy) musicians.
