Tech house is a subgenre of electronic dance music that combines elements of techno and house music. It emerged in the late 1990s and has continued to evolve and grow in popularity over the years.

The origins of tech house can be traced back to the late 1980s and early 1990s, when house music was beginning to gain popularity in the United States and Europe. At the same time, techno was also gaining popularity, particularly in Detroit and Europe.

In the late 1990s, a number of DJs and producers began experimenting with combining these two genres, resulting in the creation of tech house. These pioneers included artists like Carl Cox, Richie Hawtin, and Danny Tenaglia, who released some of the genre's earliest and most influential tracks.

One of the key characteristics of tech house is its focus on incorporating elements of both techno and house music, including the use of electronic instruments, repetitive loops, and four-on-the-floor beats. It also often incorporates elements of other genres, including elements of funk, soul, and even jazz.

Over the years, tech house has undergone numerous changes and spawned a number of subgenres, each with its own unique sound and aesthetic. Some of the most notable subgenres include deep tech, minimal tech, and techno house.

Deep tech is characterized by its deep, moody sound and focus on basslines and grooves. It emerged in the early 2000s and has become a popular subgenre, with notable artists including Nicole Moudaber and Josh Wink.

Minimal tech, on the other hand, is characterized by its stripped-down, repetitive sound and focus on simplicity. It emerged in the mid-2000s and has become a popular subgenre, with notable artists including Richie Hawtin and Ricardo Villalobos.

Techno house, as the name suggests, is a subgenre that combines elements of techno and house music. It often incorporates elements of both genres, as well as elements of other genres like funk and soul. Notable artists in this subgenre include Carl Cox and Danny Tenaglia.

In addition to these subgenres, tech house has also been influenced by a number of other genres and styles over the years. These include techno, house, and even hip hop, which has had a significant influence on the genre.

Today, tech house remains a popular genre around the world, with major festivals and events dedicated to it and new artists emerging all the time. It's a genre that has always been closely tied to technology and the use of electronic instruments, and as technology continues to advance, it's likely that we'll see even more innovative and groundbreaking sounds in the world of tech house.

Overall, the evolution of tech house has been a fascinating journey, with a rich history and a bright future ahead. From its humble beginnings as a hybrid genre to its current status as a global phenomenon, tech house has come a long way and continues to push the boundaries of electronic dance music.
