[Intro]
String theory
(Coming in clearly)
What is your frequency
(Unspeakably?)
[Verse 1]
Does your Hertz
(Cure what hurts)
Does your music
(Cure the sick)
[Chorus]
String theory
(Coming in clearly)
What is your frequency

[Bridge]
If it’s music to my ears
(Then it cures all my fears)
Producing all the frequencies
(Harmonically)
Hz, Hz, Hz,
(Hz, Hz, Hz)
[Verse 2]
Does your hertz
(Hurt or heal)
What’s the deal
(Repel or flirts?)

A SCIENCE NOTE
Hertz (Hz): The base unit of frequency, equal to one cycle per second
The similarity of scales ultimately depends on their interval structure rather than the exact reference pitch. This means the “scale experience” can be replicated across different tuning standards, as the relationship between notes remains unchanged. Whether you tune A to 440 Hz, 432 Hz, or another frequency, the intervals are what define the scale’s character. While sound waves and frequencies determine the physical pitch, the tuning standard is simply a reference point and does not alter the musical relationships between notes.
You can reference String Theory — “A piano or violin string can resonate or vibrate in various patterns, producing multiple tones simultaneously. These include a fundamental tone and higher overtones (and sometimes lower undertones). The richness and beauty of music arise from the intricate interplay of these harmonics,” explains Edward Witten. (Notice the shape of the strings in the picture. Each string is playing a wide variety of frequencies.)
Music encompasses a wide range of audible frequencies, with live and recorded music differing in frequency range and dynamics depending on the instruments used and the acoustics of the environment. The piano, with its 88 keys, spans nearly the entire range of human hearing (approximately 20 Hz to 20,000 Hz), but music often extends beyond these bounds through techniques like note bending. For example, a blues guitarist may manipulate a single note to produce subtle frequency variations, creating emotional resonance and engaging the listener in unique ways.
In addition to audible frequencies, inaudible frequencies can also have physical effects. Extremely low frequencies (known as infrasound) are often felt in the body rather than heard. These vibrations can create a tactile experience, impacting listeners on a visceral level, such as the rumble felt during a live bass performance or a cinematic explosion. This interplay between audible and non-audible frequencies contributes to the emotional and physical experience of music, though more research is needed to fully understand the mechanisms behind these effects.
While sound and frequencies can have calming and therapeutic effects, claims of specific frequencies directly causing physical or emotional healing remain largely unproven. Evidence supports broader uses like music therapy and relaxation techniques, but more rigorous studies are needed to validate frequency-specific healing.
Since most live music encompasses a wide range of audible frequencies, the specific tuning standard for the A note (e.g., 440 Hz or 432 Hz) plays a relatively minor role in the overall listening experience. What resonates with listeners is the interplay of frequencies across a piece of music, particularly the harmonic combinations of notes—such as the emotional contrasts between major and minor chords—that evoke feelings of joy, melancholy, or tension.
Moreover, the format of the music significantly influences the frequency response. Live performances deliver a full spectrum of sound, including subtle overtones and spatial acoustics, while recorded music, especially if compressed, can alter the richness and range of frequencies reaching the listener’s ears. Beyond tuning and recording methods, the dynamic and unpredictable nature of musical compositions often triggers physical responses. For example, the rising tension, sudden shifts, or crescendos in a piece of music can produce sensations like goosebumps or shivers, a phenomenon linked to the release of dopamine in the brain during moments of heightened emotional engagement.
In essence, while tuning standards provide a framework for harmony, the emotional and physical impacts of music are driven more by its structural, performative, and acoustic qualities than by the exact frequency of any single note. This underscores the complexity of music’s influence on human perception and emotion.
