The Three Frequencies and Their Contexts of Use

440 Hz - The Standard A

This is the universally recognized frequency for tuning musical instruments.
Known as the "international A", 440 Hz is the standard in modern performances,
providing a clear and stable base for intonation.

432 Hz - A Historical Alternative

432 Hz is sometimes used as an alternative to 440 Hz. Some musicians prefer it for its
slightly lower pitch, which is perceived as softer and warmer. While not an official standard,
it’s appreciated in certain musical circles for its unique expressiveness.

415 Hz - The Choice for Baroque Music

Approximately a semitone lower than 440 Hz, 415 Hz is primarily used for performing Baroque
and early music. It provides authentic and historically faithful intonation, making it the
preferred choice for historical instruments like harpsichords and Baroque violins.

Simplicity and Precision

and immediate experience. Its straightforward interface is designed to minimize distractions,
