Music Note Frequency Chart
Note Frequencies:
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 - 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 containes 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... Heres your chart :)
