I've come up with a puzzle that is both long, difficult, musical, mathematical and, I think, soluble given some patience. Here goes:

Answer each of the folowing clues, then find the 2 patterns that emerge, one mathematical, one musical.

1. Square, or H
   
2. Sweet (or Candles?)
   
3. A cold month in a year that doesn't hop
   
4. North Dallas
   
5. A Pack of fun, no joke
   
6. Commander of a fleet (of old computers?)
   
7. Meditate on the flag
   
8. The end of my job, in a sense
   

The first person to come up with the full answer gets a BIG prize, which I'll think up later :)
