This composition struck me as the start of a quest, when the entire journey lies ahead and one begins with eager anticipation of adventures to come. Again, one of my innocent optimistic tunes from the 1970s when I was in my late teens.
You know, I always hear full orchestration when I write these things, then just jot down the basic sketch and leave it at that. But try to hear the timpani and the French horn and the string section. If you can, I'll never have to bother multi-tracking it!
