Abstract

In an electronic musical tone generator where a first derivation circuit provides all the musical tones of a scale from a single tone, a second derivation circuit is selectively connected to any one of the tones produced by the first derivation circuit through a selection circuit. By selecting any of the tones of the first derivation circuit, the key of the tones produced by the second circuit may be rapidly transposed.
