How important elements of music are

They are important for 2 reasons:

1. Performing/analysing Music – An understanding of the musical elements will enable you to understand any piece of music, whether you are trying to perform the piece or analyse it. If we know the key elements that make up a car then we can use them to compare any car around the world from a Ferrari to a pickup truck by asking some simple questions – “What size engine does it have? What colour is it? How many wheels does it have? etc..” In the same way, we can understand any piece of music by asking questions – “What is the tempo? How loud is it? What key is it in? What instruments are playing? Etc…”

2. Composing Music – The musical elements are your “composer’s toolbox” – without a clear understanding of the elements of a car you will never be able to build a car. Without a clear grasp of the elements of music your ability to write music will be seriously compromised and you will not be able to reach your potential as a composer (whatever style you are wanting to write in).
