Does the open F# string produces any (minimal) infrasound (a sound below 16 Hz)? The freq. of low F# is 23.12 Hz, so the octave lower would be an infranote (ultra low F#) with freq. of 11.56 Hz. Would the open F# string be resonated treating with ultra low F# infrasound? Sorry guys, if the question is stupid but I am just curious.
