Wow!!! I'm very excited about this! I look forward to hearing it live! It seems a very ambitious work to compose, and very ambitious for a choir to sing as well considering its length and complexity Karl Henning
is gently pushing the work, as I mentioned above.
Thank you for the nice comments: as far as being "very ambitious," all I can say is that the original work would have been nearly an hour long, i.e. I simply had a certain conception for the structure in my head 45 years ago, and certain melodies of course, and did not really think about the length, and did not consider the work to be ambitious at all!
When bringing it to fruition a year ago, I began to have second-thoughts about the length, and so cut it short by c. 100 bars.
And of course my mental choir has lungs like hot-air balloons, and can sing like Pavarotti
However, in "orchestrating" the piece, I did stay conscious that singers need to breathe now and then! In my earlier days, I may not have been so cognizant of that necessity!
