The following sentence has been revised in several ways. Which of the revisions does not improve the awkward or illogical construction?

Harmony is when two or more tones fit together in a pleasing combination of sounds.

Harmony occurs when two or more tones fit together in a pleasing combination of sounds.

When two or more tones fit together in a pleasing combination of sounds, harmony occurs.

The definition of harmony is when two or more tones fit together in a pleasing combination of sounds.

Answer 1

When two or more tones fit together in a pleasing combination of sounds, harmony occurs.

Answer 2

The definition of harmony is when two or more tones fit together in a pleasing combination of sounds.

Step-by-step explanation:

This phrase is awkwardly put together and is not sure if it is explaining harmony or the definition of harmony. The problem with the main phrase "harmony is when two or more tones fit together in a pleasing combination of sounds" is repeated in this revision. You can't say "Harmony is when", because harmony is not a moment in time. It might occur in a moment in time, though, which makes much more sense.
