Frequency to Musical Note Converter
This calculator helps you convert a sound frequency (in Hertz) into its closest musical note. It uses the standard tuning reference where A4 = 440 Hz. The result shows both the English notation (A, B, C…) and the European solfège system (Do, Re, Mi…).
How Frequency Maps to Notes
Musical notes are spaced logarithmically. Each octave represents a doubling of frequency, and each semitone is separated by a factor of the twelfth root of two. This calculator finds the nearest semitone based on that mathematical relationship.
About Solfège vs English Notation
The English system uses letters (A–G), while the European solfège system uses syllables (Do–Si). Both represent the same pitches; only the naming convention differs. This tool shows both to make it useful for musicians, producers, and students worldwide.
