In a key input indicating tone generating system for small-sized electronic devices, key switches are classified into a plurality of groups according to their function. When key switches belonging to a group of key switches are operated, music tones are generated. When the key switches of at least one of the remaining groups of key switches are operated, tones different from the above mentioned tones are produced.
