While that previously referenced scientific article concludes is that the frequencies (Hz) of the notes :
a segment of approximately one second was selected in
the middle of the chord. The sound was saved as a
file, and using some Mathematica subroutines from
[2, chapter 14] a Fourier Transform was run on the
list of data. There were 29,375 frequencies present,
which included not only the notes being struck, but
also harmonics, as well as any other frequencies that
might have arisen during the recording.
What George Harrison played on his 12 string
was nothing like any of the transcriptions: he played
A2 A3 D3 D4 G3 G4 C4 C4, most likely on string
sets 2 through 5 – eight strings with six open strings
in total; (for a great chiming effect).
