Our biology is literally tuned to the physics of whole numbers. We find those whole number ratios in music 'right' because our brains are evolved to reward us for finding order in the vibration of the universe.

Why musical notes are of specific frequency. Why all the beings are able to understand. What is the relationship between mind / consciousness and the physical frequency.
Preguntas frecuentes
The fundamental frequency, also known as the first harmonic, is the lowest and purest pitch a string can produce. It occurs when a plucked string moves in one large arc between two fixed points. This basic vibration pattern is dictated by the physical setup and length of the string, forming the foundation of the specific note that your brain recognizes as music.
Standing waves are specific vibration patterns governed by physical constraints, such as a guitar string being tied at the bridge and the nut. These fixed ends are called nodes, which are points that do not move, while the middle of the vibration bows out into an antinode. This geometric arrangement ensures that the resulting sound is a structured note rather than a random or chaotic rumble.
Harmonics are a series of vibrations happening simultaneously within a single note. While the string vibrates at its fundamental frequency, it also vibrates in halves, thirds, and fourths at the same time, similar to a nested doll of vibrations. These overlapping patterns, known as the first harmonic and subsequent harmonics, create the complex and rich sound we experience when a string is plucked.
