What is 432 Hz music?
432 Hz is an alternative tuning standard where the note A above middle C is tuned to 432 Hz instead of the modern standard of 440 Hz. The entire song shifts down slightly, which many listeners describe as warmer, softer, and more natural. It is often called Verdi tuning after composer Giuseppe Verdi, who advocated for lower tuning in the 1800s.
What are Solfeggio frequencies?
Solfeggio frequencies are a set of specific frequencies — 174, 285, 396, 417, 528, 639, 741, 852, and 963 Hz — commonly used in modern sound-healing frameworks. Each is traditionally associated with a different emotional or spiritual theme, though these associations come from sound-healing culture rather than clinical research.
Is 432 Hz better than 440 Hz?
Neither is "better." 440 Hz is the global tuning standard that coordinates modern music. 432 Hz is an alternative that many listeners find softer and more comfortable, especially for meditation, prayer, or rest. The best way to decide is to listen to music you know at both tunings and notice what feels right to you.
Can retuning music cure illness or heal the body?
No. Re-Tuner does not make therapeutic or medical claims. Retuning music does not cure disease, repair DNA, remove trauma, or produce any specific health outcome. It is a listening practice. If you have a health concern, consult a qualified healthcare professional. See our full disclaimer for details.

Can I retune Apple Music?
Yes. The dedicated app for Apple Music retuning is HZP, which connects to your Apple Music account and streams retuned audio on web, desktop, mobile, Apple TV, Android TV, and Fire TV. HZP has a free tier (20 songs forever) and paid plans from $2.99/mo.
Does retuning damage the music or audio quality?
A well-built retuning tool preserves the song. The melody, lyrics, rhythm, and vocals stay recognizable; only the tuning foundation shifts. Poor pitch-shifting software can introduce artifacts, but the apps we link to use high-quality pitch processing.
What is the difference between pure tones and retuned music?
A pure tone is a single steady frequency with no melody or structure — often used for meditation or sleep. Retuned music is a full song (with melody, lyrics, rhythm) that has been shifted onto a different tuning foundation. Pure tones give you the frequency directly; retuned music gives you the frequency through music you already love.
Are all "432 Hz" YouTube videos actually at 432 Hz?
No. A title or thumbnail is not proof the audio was correctly retuned. Many uploads labeled "432 Hz" or "528 Hz" are mislabeled or only approximately tuned. The only reliable way to hear a specific frequency on purpose is to retune the music yourself with a tool that lets you choose the frequency directly.
Can I convert my MP3 files to 432 Hz?
Yes. For a single song, Song Retuner is a free browser tool that handles one file at a time. For a whole library, HZ Detect runs on Mac or Windows and batch-converts folders of music with the frequency you choose.
Does Re-Tuner recommend any particular frequency?
No. We present information about each frequency so you can make your own informed choice. The apps we link to are tools that enable the choice; the choice itself is yours.
What is Verdi tuning?
Verdi tuning refers to A4 = 432 Hz, named after Italian composer Giuseppe Verdi, who objected to the rising pitch standards of his time in the 1800s. He advocated for a lower, more stable tuning linked to C = 256 Hz. "Verdi tuning" is modern shorthand for A = 432 Hz.
What is A440 and why is it the standard?
A440 means the note A above middle C is tuned to 440 Hz. It was formally endorsed at a 1939 international conference in London and later codified by the International Organization for Standardization as ISO 16. It became standard because industrialized music — recording, broadcasting, mass manufacturing — needed a single global reference pitch.
