Dear Rainer,

Thanks for your interesting observation about Mersenne.

I had always assumed that the music on folio 1v of the ML lute book was
associated with change-ringing. Bob Spencer cautiously suggests this as
a possibility on page xxi of the facsimile:

"Forty-six permutations of the scale of C major in bass clef, suggesting
changes for bell ringers, or sight-singing exercises."

The seventeenth century was when change-ringing evolved in England, so
the connection with Folio 1v is not implausible. The first bar consists
of a downward scale of 8 notes in C major. It is normal for bell-ringers
to begin with a series of these downward scales, called rounds, before
branching off onto some method or other. I think it is significant that
the notes alter, from one bar to the next, with adjacent notes changing
places, just as they do in bell-ringing. For example, after that first
bar of CBAGFEDC, there comes CBAFGEDC. In other words, F and G (in 4th
and 5th places) have swapped places. In the next bar we have CBAFEGDC,
so G and E (in 5th and 6th places) have swapped places. This is what
happens in change ringing. As far as I know, the changes on folio 1v do
not make up a recognised method, but I could try to find out more.

Wild speculation: one of the scribes of the ML Lute Book was into bell
ringing.

Further speculation: she was called Margaret. :-)

All the best,

Stewart.

Dear lute netters,

as some of you may know Robert Spencer (editor of the facsimile edition
of the 
ML lute book) was puzzled by the f 1v which contains a list of 46
permutations 
of 8 notes and by the list of factorials on 56r.

Yesterday I noticed that Mersenne's

        HARMONICORVM LIBER PRIMVS

published in 1636 (I am afraid I even don't know if this is a Latin
version of 
his famous Harmonie Universelle) contains:

* A complete list of all 24 permutations of 4 notes.

* A list of factorials from 1 to 64.

Note: 64! has 90 digits and this is probably the largest factorial
calculated 
without computers.


By the way, a complete list of all permutations of 8 notes would require
to 
write down 8! = 40320 permutations, which is beyond discussion.

Anyway, obviously the scribe computed 8! on f. 56r which probably is not
a 
coincidence.


Wild speculation:

One of the scribes knew Mersenne's book.
