Tuning music to Solfeggio frequencies involves adjusting a song so specific notes align with target frequencies like 396 Hz, 417 Hz, or 528 Hz. The process usually involves retuning the project’s reference pitch, using pitch-shift tools, or generating exact drone tones for meditation-style audio. The article explains the difference between traditional solfège singing systems and modern Solfeggio frequency concepts often associated with wellness and sound healing. It also covers practical workflows for MIDI instruments, recorded audio, and multi-frequency projects while highlighting common tuning mistakes to avoid. Although alternative tunings are musically valid, the article notes that scientific evidence supporting specific healing claims for Solfeggio frequencies remains limited.
