About 440 Hz
440 Hz, also known as A440, is the international standard pitch for tuning musical instruments. This means that the note 'A' above middle C vibrates at 440 cycles per second. While this is the modern standard, it hasn't always been the case - historical tuning varied significantly. The adoption of 440 Hz as a standard helps ensure that musicians around the world can play together harmoniously. Some musicians and sound healers prefer alternative tunings like 432 Hz, arguing it sounds more natural or harmonious.
