See all note frequencies in an organized chart. Keep in mind human hearing is from 20hz to 20,000hz. Note frequencies in that range have been grayed out for that reason.

Note Frequency Chart
This is the note frequency chart that I find most useful.
|Note||Oct -1||Oct 0||Oct 1||Oct 2||Oct 3||Oct 4||Oct 5||Oct 6||Oct 7||Oct 8||Oct 9||Oct 10|
*Note - Some of the grayed out low note frequencies in this chart may be felt rather than heard. You'd need a sub that can reproduce frequencies that low, however.
1Khz(kilohertz) = 1,000Hz(Hertz). 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.
Note Frequency Chart 2
Maybe you want your root note length in milliseconds to coinside with the tempo of your song. This Note frequency Chart contains the MIDI number, note name, frequency and period.
The tuning of A4 is the measurement and tuning standard for Western music. Throughout the years A4 has ranged between 400 Hz and 480 Hz. Eventually a standardized pitch of 440 Hz for A4 was set. Many musicians and others prefer A432 instead of A440. Google it... 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. (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.
I digress... Here's your chart :)

Note Frequencies and Music
Note frequencies refer to the specific sound frequencies that each musical note produces. 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.
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. This led to the development of the 12-tone equal temperament system, which is used as the standard tuning system for most Western music. 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.
Frequency and Tuning
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"). 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. For example, the frequency of C4 is 261.63 Hz, while C5 is 523.25 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, in the 18th and 19th centuries, A4 was often tuned to a lower frequency, around 415 Hz. This difference in reference frequency is known as pitch standard, and it can have a significant impact on the sound of the music.
Music Theory and Frequencies
Understanding note frequencies is important in musical theory and in tuning instruments. The accurate tuning of notes is essential to producing harmonious music, and deviations from the standard tuning can result in an inharmonic sound. For example, if two instruments are playing the same note but are out of tune with each other, the result will be a discordant sound.
Instrument shape, Material and Sound
Instrument makers must carefully consider the note frequencies when designing and building their instruments, as different materials and shapes will affect the way the instrument vibrates and produces sound. For example, a violin string will vibrate at a different frequency than a guitar string of the same length and tension, because the two instruments are made of different materials and have different shapes.
In addition to the material and shape of the instrument, the method of playing can also impact the note frequencies. For example, a brass instrument player can produce different note frequencies by adjusting the lip tension and the shape of the oral cavity, while a string player can produce different note frequencies by adjusting the pressure on the strings and the position of the finger.
To summarize, note frequencies are a crucial aspect of music, as they determine the specific sound frequencies that each musical note produces. Understanding the relationships between frequency and musical notes is essential for tuning instruments, composing music, and appreciating the harmonious sounds of music. The standard tuning for most Western music is based on a 440 Hz reference frequency for the note A4, but other reference frequencies have been used in the past and are still used in some cultures. Regardless of the reference frequency, the accurate tuning of notes is essential for producing harmonious music.
