MIDI Note Number to Frequency Conversion Chart

For example, in the 18th and 19th centuries, A4 was often tuned to a lower frequency, around 415 Hz. It is important to note that while 440 Hz is the standard reference frequency, other reference frequencies have been used in the past and are still used in some cultures. For example, the frequency of C4 is 261.63 Hz, while C5 is 523.25 Hz. This note serves as a reference point for all other notes, and from this reference point, other notes can be calculated using mathematical relationships based on the musical scale. The standard tuning for most musical instruments is based on a 440 Hz reference frequency for the note A4 (which is often referred to as 'Concert A'). In this system, the interval between any two adjacent notes is a fixed ratio, making it possible to play in any key without significantly altering the sound of the music. This led to the development of the 12-tone equal temperament system, which is used as the standard tuning system for most Western music. The relationship between frequency and musical notes has been well-studied, and it has been found that certain frequency ratios sound harmonious to the human ear. In Western music, these notes are named (A, B, C, D, E, F, G) and each note has a corresponding frequency in hertz (Hz), which is the unit of measurement for frequency. Note frequencies refer to the specific sound frequencies that each musical note produces. (If you see an image representing the golden ratio, notice how it looks like a shell that is formed in nature - and how that looks similar to something like a tuba. Here are some terms if you want to go down that rabbit hole: A432, superior temperament to A440, middle C C4 256 Hz, Schuman resonance, Universe Golden Mean, Golden Ratio. Many musicians and others prefer A432 instead of A440. Eventually a standardized pitch of 440 Hz for A4 was set. Throughout the years A4 has ranged between 400 Hz and 480 Hz. The tuning of A4 is the measurement and tuning standard for Western music. This Note frequency Chart contains the MIDI number, note name, frequency and period. Maybe you want your root note length in milliseconds to coinside with the tempo of your song. So when someone says, 'Boost 12K,' they mean boost at 12,000Hz, which is between F#/Gb and G on the Note Frequency Chart at Octave 9. You'd need a sub that can reproduce frequencies that low, however.ġKhz(kilohertz) = 1,000Hz(Hertz). *Note - Some of the grayed out low note frequencies in this chart may be felt rather than heard.
