An Arrangement

What is an arrangement?

An arrangement can be split into two things:

1. A cover - a piece of music or a song that is similar to the original but has been altered slightly to suit the new writer or composer.
2. An arrangement - where a piece of music or a song has been completely changed.

Example of a cover: https://www.youtube.com/watch?v=PGoCtJzPHkU - In this video the girl is singing Titanium by Sia acoustically and stripped back with just a piano in the back ground. 

Example of an arrangement: https://www.youtube.com/watch?v=Bv0NDgCzl6U - In this video the man completely changes the song entirely by using a key board piano as the music and the singing.
