To process music, we have a structure of specific neural networks. We know that they are independent of the networks responsible for processing speech and ambient sounds. It is known that people who stutter while speaking can sing without stuttering (By the way, I got rid of stuttering in my childhood thanks to singing).
When we listen to a musical composition, various processes are activated in our brain: melody analysis, musical memory, recognition, emotional reaction, and many others. The integration of all these processes occurs as a result of a complex brain process in which several neural networks are simultaneously or sequentially involved.
Based on studies of patients with brain damage, researchers Peretz I. and Coltheart M. have developed a
model of the functional architecture of music processing. According to this model, music processing is organized in two independent and parallel systems.
The melody system processes all information about the melodyIt distinguishes between two key components: tones (each note of a melody) and intervals (the distance and direction between notes). To perceive the contours of a melody, you need to integrate them into a single way of perception.
The time system is responsible for embedding the melody in the time spaceIt also operates with two components: rhythm (the duration of sounds and pauses) and musical metre, which are integrated into a single way of perception.
