ok random post.
techno =/= trance pls understand this well lol

Techno
1. Techno mainly focuses on percussion - the beats, while the melody is usually non-existent or very subtle in a techno track. By employing a wide variety of abstract drum patterns, techno doesn't need a melody to make it interesting.
2. Techno generally has fewer layers than trance, so it may seem more repetitive, but this allows it to be layered nicely on top of other techno tracks without sounding too busy.
3. Build-ups are rare in techno. Instead, a techno song usually consists of constant pumps of high energy.
4. Techno is older than trance, originally created in the early-to-mid 80s by black Americans in Detroit.
5. Techno is generally harder than trance, groovier, it makes you want to forget about your problems and dance like a crazy person all night long!

Trance
1. Trance mainly focuses on the melody. It's all about the lead synths, whooshing pads, and pretty strings.
2. Trance generally has more layers than techno, and for this reason it is usually less repetitive since there is more to add or subtract and change up the sound.
3. Trance usually has one or more build-ups, each followed by a release.
4. Trance is newer than techno, created in the early 90s by white people in Europe (Germany originally).
5. Trance is more uplifting, it is music for the mind. It finds escape in dreaming more than it does in dancing, though it's good for that too!

most of the comparison extracted from somewhere.
techno and trance are very different..
