Quote James Percival:Quote Daniel Davis:
Polyphony (music containing more than one simultaneous note) is a western European invention which arose almost two millennia after King David. It is hardly likely that David had even the concept of a chord let alone a secret one which pleased the Lord.
Not necessarily. Harmony was certainly anathema to the Greeks (who considered the octave to be the only permissable consonant interval).
The perfect 4th and 5th were also widely used (and indeed the 5th is the interval that is the basis for the system of Pythagorean tuning); it was the so-called major third that was and has been the problem historically, and was considered dissonant right through to beginning of renaissance polyphony.
It is clear that their conception of harmony differed greatly from ours of course, and that melody and (mode) was far more important.
