Actually, theoretically, semitone changes are some of the least subtle changes you can make. The second key has almost no relationship to the first key. If you want to hear subtle modulation, try some Debussy. Changing to the V of V or even the V can be very, very subtle. This is where having a basic background in music theory comes in handy!
