Condisering Key Changes : Does Key changes of different intervals produce different effects on the Audience similar to intervals? Does Key changes have different quality to them and if so what are they called
Yes, they do have different effects.
Often the difference is one of distance, or smoothness. A modulation from C to G will sound very smooth, because there's only one pitch that is different between C and G major. A modulation from C to F♯, though, will sound rather distant, because there's only one pitch in common between the two keys (there are sort of two pitches in common, but technically they're different: F and E♯).
But defining exactly what these qualities are is much more difficult and opinion-based. With that said, there are some modulations (or chord changes) that have been used with some consistency throughout history for particular effects. A common one is discussed by Richard Cohn in this famous article; he shows that motion between two "hexatonic poles," like C major and A♭ minor, is often used to express an "uncanny" effect in music by Wagner.
