“There is geometry in the humming of the strings. There is music in the spacing of the spheres.”
— Pythagoras
Perfect Fifths
The Perfect Fifth is a musical interval that is often experienced as calming and harmonizing. In music, it forms the basis of harmony, creating a sound that feels balanced and stable. In musical terms, the interval occurs when one note vibrates at a 3:2 ratio relative to another.
The discovery of musical intervals is often credited to Pythagoras (569—475 BCE), who explored the mathematical relationships between notes. Listen to your favorite movie soundtrack and you can sense how intervals create tension, excitement, and resolution. The first two notes of the Star Wars theme (perfect fifth) feel very different from Jaws (minor second).
My own work approaches musical intervals as experiential tools, using instruments such as singing bowls and tuning forks. I combine different intervals to create a sound journey unique to each person. The Perfect Fifth is a staple in my sessions. Its open, balanced sound is especially effective at helping settle the nervous system.
Want to experience the power of the perfect fifth for yourself? Hold these C&G tuning forks, one in each hand. Tap them on a semi-hard surface (your knee, a hockey puck) and bring one fork to each ear. Hold them until the sound fades out. Switch hands and repeat. Take a moment to breathe and notice how much calmer and centered you feel from just a moment before.
Further reading: Modern-day tuning fork pioneer John Beaulieu studied how each interval affects us on all levels - emotionally, mentally and physically - relating each interval to different elements. He writes about his work in his book, Human Tuning: Sound Healing with Tuning Forks, which I recommend as a resource for anyone interested in this topic.
