Quick Answer

The Frequency to Note utility instantly converts sound frequencies in Hz to musical notes like A4 at 440 Hz, using equal temperament tuning where each semitone multiplies by the twelfth root of 2 (≈1.059463).[1][2][5] Enter any Hz value—such as 98 Hz for G2 or 261.63 Hz for C4—and get the exact note, octave, and cents deviation for tuning, mixing, or analysis.[3][4][5] Pianos span 27.5 Hz (A0) to 4186 Hz (C8) across 88 keys, making this tool essential for over 50 million musicians worldwide.[3][5][6]

Why You Need This

Converting frequencies to notes solves pitch identification in music production, instrument tuning, and sound design, where manual math is complex due to the logarithmic scale.[1][2][5] A4 = 440 Hz is the global standard, with octaves doubling frequencies (e.g., A5 at 880 Hz), and pianos covering 27.5-4186 Hz.[1][3][5] Music producers cut muddiness at ~200 Hz, boost vocals at 2-5 kHz, while guitarists and luthiers tune to precise Hz like 130.8 Hz for C3.[2][3] Audio engineers, educators, and live performers rely on it for harmony and EQ.[1][4]

How It Works

The tool uses the formula ( f(n) = 2^{(n-49)/12} \times 440 ) Hz or inverse ( n = 12 \log_2(f / 440) + 49 ) for equal temperament, referencing A4 at 440 Hz.[3][5] Input the fundamental frequency (e.g., 1109 Hz outputs B5 with cents), ignoring harmonics for core pitch.[1][4] It outputs note name, octave, and deviation (1 cent = 1/100 semitone), supporting piano's 8 octaves from 16.35 Hz (C0).[2][4][5]

Tips for Best Results

  • Enter the fundamental frequency only, typically 50-400 Hz for mid-range.[1][2]
  • Specify octave if ambiguous (frequencies double per octave).[4][5]
  • Use 440 Hz reference; note alternatives like 432 Hz shift all notes.[2][3]
  • Verify by playing the note against your source for zero cents deviation—ideal for guitar strings or EQ notches.[1][6]
