    Does anyone know the frequency of the open E string?

    In addition, does anyone know the frequency when its dropped to D?

    As I recall, open E is just over 40Hz. Not sure about the D, but the B below is about 30Hz, so you're looking at somewhere around 38Hz. Of course, the tonal characteristics of the sound you hear also have a good measure of harmonic overtones blended in, which is why you can still get a good illusion of a low E even if your amp starts rolling off somewhere above 40Hz.

    Any particular reason why you ask?

    B is 30.868Hz.
    E is 41.203Hz.
    A is 55Hz.
    D is 73.416Hz.
    G is 97.999Hz.

    Good old differential equations class, I knew it would come in handy one day.;)

    thanks for the info, but do you happen to have the A just below low B?

    In that case, D below the open E will be half the frequency of the open D (up one octave = double frequency)....

    ... about 37 Hz (so I was a little bit out)

    Hope the rounded numbers don't offend anyone, but I went on to study history, not maths ;)

    As wulf said, you always multiply by two to get the next octave of a given note.

    So, for A

    A0 = 27.5Hz
    A1 = 55Hz
    A2 = 110Hz
    A3 = 220Hz
    A4 = 440Hz

    Hope that helps.

    So...which ones the brown note ;)

  9. It's 7.something Hz, isn't it?
  10. brown note = 96 cents below the lowest E flat

    im studying all of this for my high school science olympiad where i had to build a guitar that resonated by having 2 styrofoam coolers bolted to the ends of the neck. sounds like a banjo and i played no one knows by queens of the stone age and actually got more points for knowing this than for playing the song...

    :) Wrong Robot is refering to a previous thread where everyone was getting carried away with accurate reproduction of the low B = 31.5hz. I nominated this as the "Brown Note" to give the south park fans a bit of a giggle but it seems to have stuck.......
