432 Hz – a gentler sound with history
More and more piano owners are having their instrument tuned to 432 Hz – and experience the sound as remarkably warm and soothing. Here is what lies behind it, and how I tune your piano to it expertly.
What does 432 Hz actually mean?
“Hz” (hertz) means vibrations per second. The concert pitch A is the reference note to which a whole instrument is tuned. Today the international standard sets it at 440 Hz. A 432 Hz tuning places this reference note slightly lower – at 432 vibrations per second.
The difference is only about 32 cents – roughly a third of a semitone. Small, and yet audible to many ears.
Why 440 Hz at all? A look at history
Concert pitch was anything but uniform for centuries: depending on country, era and instrument it ranged from about 415 to 460 Hz. Only in 1939 was 440 Hz fixed as the international standard.
Precisely because pitch was fluid for so long, 432 Hz holds a special appeal: it recalls a time when instruments often sounded lower and mellower. Even the composer Giuseppe Verdi championed a pitch close to 432 Hz – which is why it is sometimes called the “Verdi tuning”.
Does 432 Hz really sound different?
Yes – subtly, but noticeably. Many people describe 432 Hz as warmer, softer and more relaxed. The physical explanation is simple: the slightly lower frequency is often perceived as less piercing.
Whether you hear the difference clearly is entirely individual. Sound is always personal perception, too – which is exactly what makes the subject fascinating.
Why many people find 432 Hz soothing
Very many people who have their piano tuned to 432 Hz describe the sound as calming, balancing and soothing – in meditation and sound work, in their own playing, or simply listening at home.
Research is approaching the subject as well: early studies suggest that music at 432 Hz is perceived as more relaxing and may go along with a slightly calmer heart rate. Sound reaches more than the ears – it reaches the whole person.
For me as a piano maker, your perception is what counts: if 432 Hz feels more harmonious and soothing to you, I will tune your instrument to it with pleasure and care – convinced that good sound is far more than technique.
How is a piano re-tuned to 432 Hz?
Technically, a 432 Hz tuning is a tuning with a downward pitch correction. If your piano currently stands at 440 Hz, I gently lower the overall string tension and then fine-tune the instrument to 432 Hz.
For a piano that has gone a long time without tuning or deviates strongly, a second appointment can be advisable for a stable result – I always discuss this openly in advance, so there are no surprises.
Who is 432 Hz for?
The 432 Hz tuning is especially valued in meditation and sound work, in yoga studios and by anyone who consciously seeks a mellower sound. Musicians playing with ensembles tuned to 432 Hz benefit as well.
And sometimes it is simply personal preference – which is reason enough. It is your instrument and your sound.
A 432 Hz tuning is a tuning plus pitch correction. You will find the exact prices transparently on my pricing page.

Is 432 Hz better than 440 Hz?
Neither better nor worse – simply different. 440 Hz is the international standard, 432 Hz a deliberately chosen alternative that many perceive as warmer. It is a question of personal preference and purpose, not of quality.
Can I have it tuned back to 440 Hz later?
Yes, at any time. Switching between 432 and 440 Hz is unproblematic for a healthy piano – technically it is just a normal pitch correction.
Can every piano be tuned to 432 Hz?
In principle, yes. The difference from 440 Hz is small and the change in string tension modest. With very old or long-neglected instruments I assess the condition first and discuss it openly with you.
