Tech house is a fusion of several music styles associated with the underground house music scene. It combines elements of house, techno, and acid house, and typically features energetic beats, looped synth melodies, and strong bass lines. Although tech house has its roots in the original house sound, it’s more associated with a more modern, tech-influenced sound.
Business techno, on the other hand, is a style of techno music designed specifically for corporate or business environments. It is designed to be unobtrusive yet stimulating, and to create a relaxed, focused atmosphere. It is upbeat, positive and usually incorporates melodic elements such as synthesizers, chord progressions and repetitive samples. It does not contain aggressive or heavy beats and is instead tailored for productivity and focus.
