Sorry, John, but I don't believe you about the 40 different lines. Oh sure, if they were mostly parallel lines, but musical parts would be more complex than that. Picture the bassoon part, hopping through broken chords while the flute wafts through a smooth, melodious line. The tympani start and stop, sometimes fast, sometimes slow, sometimes loud, sometimes soft. Keep doing that for 30 musicians or 40 choir members.

Very hard to decipher, visually.
