Which Konami arcade game directly inspired the original Guitar Hero?

Konami’s Guitar Freaks directly inspired the original Guitar Hero. The Japanese arcade game used a guitar-shaped controller with fret-style buttons and a strum control, establishing the basic idea of performing music by matching on-screen notes.

RedOctane’s founders encountered Guitar Freaks and saw an opportunity to bring a similar guitar-based experience to North American home consoles. RedOctane initially worked on guitar controllers, then approached Harmonix, whose developers had already made rhythm games such as Frequency, Amplitude, and Karaoke Revolution. Together, the companies built Guitar Hero for the PlayStation 2.

The other choices are also Konami music-game names, which makes them tempting mix-ups. Beatmania focused on DJ-style inputs, while Dance Dance Revolution used floor panels; ParaParaParadise centered on motion-based hand gestures. Guitar Freaks is the one whose guitar hardware and note-matching format most directly led to Guitar Hero’s design.
