When we look at traditional and modern ways to create harmony in music, there are some important differences to notice:

1. Voice Leading:

   • Traditional: This style focuses on smooth transitions between musical notes. It follows certain rules, like counterpoint.
   • Modern: This style often breaks those rules to create interesting effects, which can lead to more tension and unusual sounds.

2. Chord Progressions:

   • Traditional: This method relies a lot on standard harmony, using familiar sequences like I-IV-V-I.
   • Modern: This method tries out new combinations, using things like modal interchange or chromaticism to make more unique sounds.

3. Dissonance:

   • Traditional: In this approach, dissonance is often seen as something that needs to be fixed.
   • Modern: In the modern approach, dissonance can exist on its own. It adds depth and interest without needing to be resolved right away.

In short, the modern way of creating harmony is more flexible and adventurous than the traditional approach.
