What is timbre in music?
Timbre is the sound or tone quality of a note played or sung. The musical instrument used to play a note changes the timbra of the note. Think about the difference between a piano and a trumpet. Even if they both play the same note, you can recognize the trumpet as sounding different from the piano. This is tone-color or timbre. You are probably familiar with some words people use to describe timbre, such as "nasally", "rich" or "thick" and "breathy".

What is encapsulation and why is it important?
If we have a program with a few different objects, and we need these objects to interact with each other while also maintaining safety against outside interference and misuse. Encapsulation is essentially the "bundling" of data and functions together. When encapsulated, each object in our program keeps its state private, such as inside a class (a form of encapsulation). Objects don’t have direct access to another objects state. Instead, they can call a list of public functions, called methods. Thus, each object manages its own state with its methods methods, and no other class can touch its state.
