If you learn to read full 'Symphonic Scores' - the conductor's copy, that is - you will see much 'doubling' of phrases by many different sections of the orchestra all the time, and much 'counterpoint & harmony...

It's not unlike playing a pipe organ with dozens of ranks of differing sounding and pitched ranged pipes to be coupled in or out as desired - or one of those organs with hammond draw bars: you have all these different tonal qualities to compare and contrast or reinforce to generate new tonal sounds.

... and you 'f*lk lot' get all excited over juggling just a couple of human voices at once like it's some new discovery?!!!
