How would you explain the difference between House, Techno, Electro, Progressive House, Progressive Trance, Uplifting Trance, Psy Trance, Deep House, D&B, Dubstep and all the sub-genres of EDM (Electronic Dance Music) to a layman?!

Extremely short descriptions of each of these: House: The last remnants of disco. Simple 4/4 beats and groovy lines. The stem cell of electronic music. Progressive House: House music that is totally cool with gay marriage. Deep House: Echo-y and repetitive. The opposite of progressive house. One of my least favorite sub-genres. Techno: Like house music but more industrial-sounding. Weaker drums and very less sound variation. Electro: Hits you heavy and hard. Hits you on the high end with screeching lines that are like 5 octaves above mid-C, and thumping low end bass. Usually 4/4. Deadmau5. Trance: Often faster than house. Trippy & more intense. Tickles the back part of your brain. Progressive Trance: Trance music that bleeds into a wide range other genres. Tends to be more melodic & interesting. Probably my favorite type. Uplifting Trance: Exactly what it sounds like. Happy, positive, bullish. Even without drugs. Psy Trance: Incredibly fast, intense, and druggy. What a mushroom trip sounds like. Drum n Bass: The http://en.wikipedia.org/wiki/Amen_break with tons of variation in every element layered on top. Dubstep: Sounds like a three-way between a robot, fax machine, and a dishwasher.

You distinguish EDM on these dimensions : Important : - rhythm ... what are the actual patterns / matrices of rhythmic elements, how fast does the music go? - timbre ... what are the typical sounds that dominate. (All genres have examples of borrowing sounds and ideas from others so it's never a hard exclusion, but there is a predominance of certain sounds in certain genres (house and garage tends to have more samples of real instruments and human voices, techno, trance and dubstep tend to have more overtly synthetic sounds ) - broad-structure ... pretty much all EDM is repetitive, but some genres focus on a continuum. All tracks blend into each other without interruption or too much of a jolt. Recent post-dubstep innovations have moved in the opposite direction to short-buildups and "drops", pauses and dramatic shifts of instrumentation and speed. - scene ... all genres have a place where they come from, an inner mythology about the kind of people who like them, the places where those people gather, the visual language that accompanies them. - feel ... all that indescribable stuff that you still know when you hear it ... is it ecstatic, sexy, spiritual, rousing etc. etc. Lesser : - era ... some music is just old-skool, you know it's a scene which is "gone". What period does it cunjour up? There are tracks that just ARE part of the Acid House / second summer of love era, even though they don't have anything much in common with your contemporary acid workouts. - harmonic language ... really isn't all that important in EDM. Most genres will encompass both melodic / harmonic and scarcely harmonic tracks. You can see a few vague trends : jazzy harmonies work well in house, some forms of drum'n'bass and footwork, but would be out-of-place in trance or dubstep.
