Cyril, I checked the Workbook (re-downloaded), it is properly updated as mentioned by Richard @Richard_close2u.

I know what you mean but I like the science behind these sort of things.

Hi Lisa,
I am talking about the change he mentioned today at 9:59am.
The new lesson page:
Practical Perspectives
Guitars only play notes between 80Hz to 1.31kHz. ** The second thickest string on the guitar is the note A, whose frequency is 110 Hz. Piano goes lower and higher (down to 27.5 Hz and up to 4.18 kHz (4180 Hz) on an 88 key piano) .
** NOTE: There is an error in the video - it is stated and written that the highest pitch on guitar is 7kHz. This is an error.
The content of PMT v2:

Hi Cyril,
aaah, now I got your point correctly and yes, you are definitely right. My bad.

Wowzers what a debate.
So as far as fundamentals go the frequency is a nowhere near 5k.
But I know editing in the studio that important frequencies exist from the guitar way above thatā¦ we are into harmonics and overtones - but they play a massive part of the sound we hear.
Just as it shows in the video when I play a not on piano the spectrum analyser shows many notes above the note played.
So thatās where I got the figure - didnāt think it would cause so much controversy and outrage lol.
Iāll see if I can tweak the video to clarify, but unlikely to be right away as I have other fish to fry right now! J

Maybe one reason so many of us older folks turn to guitar is that they play in frequency ranges we can still hearā¦
