In the 1700's, Bach would play a fugue, in the 1970's the synthesizer was created by who?...I've been trying to figure this out but all I get is Robert or Bob Moog and it was incorrect...

Robert Moog.

Explanation:

A synthesizer is a musical instrument that generates tones electronically by means of sound synthesis, being one of the central tools in the production of electronic music. Although many attempts were made before, the first effective synthesizer was invented in the 1970s by Robert Moog.

A distinction is made between analog and digital synthesizers. As in many areas of technology, digital devices have partially replaced pure analog technology. However, analog devices are still used because of their distinctive properties. Many older devices have achieved cult status among musicians. The characteristic sound of certain common devices and the creative use of their peculiarities has often influenced the development of entire musical styles, such as acid house, techno and drum and bass.
