If you have explored sound healing, you have likely encountered debates about which frequency is "most healing." Two names dominate the conversation: 432Hz and 528Hz. Both are audible tones in the mid-range of human hearing, and both have devoted communities — but they serve different philosophical and practical purposes.
432Hz: The "Natural" Tuning
432Hz is often called the "natural" or "Verdi tuning" frequency. Proponents claim it aligns with nature, mathematics, and the body's resonance — citing references to ancient instruments, planetary cycles, and water cymatics experiments. Music tuned to A=432Hz (instead of the modern standard A=440Hz) is described as warmer, more harmonious, and less stressful to the nervous system. Many crystal singing bowls and meditation tracks are tuned to 432Hz or its harmonics. While rigorous clinical evidence remains limited, countless practitioners report that 432Hz music feels subjectively calmer and more grounded.
528Hz: The "Love" or "Miracle" Frequency
528Hz occupies a different niche. Often labeled the "love frequency" or "DNA repair frequency," it gained prominence through Dr. Leonard Horowitz's work and the growing solfeggio frequency movement. Advocates associate 528Hz with transformation, heart-centered healing, and cellular repair. It sits higher in pitch than 432Hz and tends to feel brighter and more uplifting. Solfeggio frequency playlists on streaming platforms frequently lead with 528Hz tracks. As with 432Hz, scientific validation is still developing, but subjective reports of emotional release and elevated mood are common.
75Hz: Heal75's Low-Frequency Approach
While 432Hz and 528Hz operate in the audible mid-range, Heal75 takes a different path with 75Hz — a low-frequency tone designed for nervous system regulation rather than melodic tuning. Low-frequency sound therapy works through a different mechanism: rather than tuning music to a specific pitch, a sustained sub-bass tone creates a physical grounding sensation that many users describe as deeply calming. The 75Hz frequency in the Healing Sounds app sits below typical musical notes, acting as a subtle anchor during meditation without demanding active listening. It complements rather than competes with 432Hz or 528Hz — think of it as the foundation beneath the melody.

Which Frequency Should You Use?
There is no single "best" healing frequency. Choose 432Hz if you want warmer, nature-aligned music for relaxation. Choose 528Hz for uplifting, heart-centered sessions. Choose 75Hz if you want a passive, grounding low-frequency anchor that works beneath any meditation style. Many practitioners layer approaches — playing 432Hz music while running 75Hz in the background through Healing Sounds.

Conclusion
432Hz and 528Hz each offer distinct subjective experiences within the sound healing tradition. Heal75's 75Hz frequency adds a low-frequency dimension focused on nervous system calm — a practical, evidence-informed complement to mid-range healing tones.
