An electronic musical instrument comprises means for detecting depressed-keys on a keyboard to generate key informations corresponding to said depressed keys, and means for generating a musical tone signal which varies pitch from the pitch of a musical tone generated by a firstly-depressed key to the pitch of a musical tone generated by a secondly-depressed key, in accordance with a key information of said firstly-depressed key and a key information of said secondly-depressed key. In the instrument, means is provided for generating an amplitude coefficient which sequentialy varies from an amplitude of the musical tone generated by the firstly-depressed key to an amplitude of the musical tone generated by the secondly-depressed key whereby the amplitude of said musical tone signal is controlled according to said amplitude coefficient.
