Pitch and music frequencies

Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their perception of the frequency of vibration (from Wikipedia). There are different pitch definitions, for instance:

  • Concert pitch: A reference pitch of a group (orchestra) of instruments.
  • Standard pitch: A pitch often defined based on the A4. Popular values are 440 Hz, Baroque pitch (415 Hz), etc.
  • Alternative pitch: A standard pitch used in esoteric, chakra, natural, and other alternative forms of music. Popular standard pitches are 432 Hz, 528 Hz, and 639 Hz. Alternative pitches are often said to sound better, be more harmonic, and have transcendental powers.

Popular frequencies

The following table lists different base frequencies, notes/scores, and the reference A4 frequency (source: Attuned Vibrations):

Frequency A4
174 Hz (F3)438.48 Hz
285 Hz (C#4)452.37 Hz
396 Hz (G4)444.34 Hz
417 Hz (G#4)441.78 Hz
432 Hz (A4) 432 Hz
440 Hz (A4) 440 Hz
528 Hz (C5)444 Hz
639 Hz (D#5)451.84 Hz
741 Hz (F#5)440.60 Hz
852 Hz (G#5)451.33 Hz
963 Hz (B5)428.96 Hz

Offline applications

If you want to convert multiple files or change the frequency in realtime during playback then offline applications might be more suitable than this online tool. The Music Speed Changer app is extremely useful for practicing because it can change the pitch in realtime while playing. The 432Hz app on the other hand can be used for converting batches of music files.
