How can I manage to write music and compose a song? Trying to understand the logical relationship between the various sounds that could be used to compose, the concepts of scale and tonality were born, which are fundamental systems for understanding how to choose notes in a composition. Or: how can I play the same piece by repeating it without having a sense of monotony? In this way, understanding that to resonate the same musical fragment without perceiving boredom, it was enough to play it in another key, the relationships between the various tonalities were studied, in order to understand how to pass from one to the other in an effective way, thus arriving at music theory. of the circle of scenes .
These are just a few examples that can show how practical music theory is . And how naturally it is essential to fully understand the principles in order to be able to write about music. It would be like writing a novel without knowing the grammar. We could only do it “by ear” but without great results.
2. Musical harmony: the scaffolding of each piece of music
The musical harmony is the material that allows to know in depth the world of the chords and is of fundamental importance since the chords constitute the skeleton, the skeleton of any piece of music . For this reason it is necessary to know it thoroughly. The principles that need to be understood to understand musical harmony are above all the following:
The chords are not isolated entities but are related to the scale and tonality in which we find ourselves: this is an essential concept since, especially in pop music, people tend to see chords as something isolated from each other. ‘other. These agreements instead have a well-defined role in the tonality and understanding it is essential to be able to learn to create sequences of chords that Sunonino well. Otherwise, even in this case we will only rely on the ear.
The more complex chords derive from the basic chords : the seventh chords, the ninth chords, or the excess fifth chords are nothing more than changes to the chords of three sounds. This is a fundamental aspect to understand in order to be able to use them to the fullest. In fact the role that has an agreement of three sounds within the key is maintained even after its modification: in essence the seventh or ninth chords, etc. they are just a different, more suggestive “version” of the basic agreements.
The modulation between the tones is an essential moment to build the musical harmony of a piece : this aspect is also of extraordinary importance. In fact, passing from one shade to another corresponds somewhat to the change in color: it is as if we wanted to make a picture all with the same color. Instead moving inside the various shades we have the possibility of being able to obtain a great and suggestive variety.
