I post this as a new thread because I don’t want to pre-occupy anyone from Stephen's thread and composition of his variations on La Folia.
I have done years ago a set of variations for bouzouki on this Folia theme, but they're lost amongst my manuscripts.
The last two years I've been working on a big song cycle called "LIBYAN SEA TALE" where I thought of using modulations as instrumental interludes, and one of the themes that came first into my mind was La Folia again. I wanted something that could take me round the clock in terms of tone steps and as Handel is one of my favourite sets I started with his setting.
So my aim was to go quickly and smoothly from Dm to Em and imo this can be done as early as from the 1st or 2nd bar of Handel's setting, if you agree. Bars 17 - 18 in this pdf behave as if the 2nd triad in Dm is not diminished but Em itself. I marked the harmonic understanding with Roman numerals for both tonalities, and after bar 19 in the new tonality only. The change sounds fairly smooth to me.
What now remains is to write my own variation instead of repeating Handel's. :-)
Perhaps what Stephen says about a competition on this theme could take ground and give all sorts of nice results.
Something like a "Composers Forum contribution to a Musical Cathedral", as the great cathedrals took centuries and many architects to be completed, so is Folia a cathedral still in progress.
How about it Gav? (After this summer preferably)
