Musicians for more than 10 years, we followed various music trainings.

During our music theory program, we were regularly confronted to the founding writing rules of the western music.

 

Indeed, music compositionrequires numerous tools, which are more or less complex and which need to be used folowing very precise rules. The use of notes and melodies, for example, is never chosen randomly : these rules answer criteria defined by the musical period (as the Baroque, classic, romantic period, etc.), by the culture (the western music is indeed very different from the oriental music for instance- moreover it is where our knowledge area is the most important, that's why we chosed in this TPE to only refer to the western music), of the researched effect (a melody can  be described by adjectives of feelings or states such as  " melancholic ", " majestic " or still "dancing"), and by many other elements.

 

To build some music, we so need to stack notes and melodies to give a tone, and to give the aforementioned felt: we then form chords.

 

The chord is a very important element in music, it serves to intensify a melody, to make it deeper. Through every periods  and the musical currents, chords have evolved and are still oftenly used today. We find them everywhere, in  group music or still in individual music, as for the piano where the chords constitute a major part of the basic teaching. That is why we decided to interess ourselves in it in a deeper way, and to study how they were formed and they evolved over time, and how we are able to perceive them.

 

At first, we will detail  the basic elements which are used in the creation of the chords, like the music scales, the notes and their evolution through time.

 

Then we will study the rules ofthe chords formation and how they were and are used in music.

 

Finally, we will finish by the perception of the chords, a subject that we will deepen thanks to the study of the particular case of the absolute pitch.
