An electronic musical apparatus employs a tone-generator section containing a plurality of tone-generator channels, each consisting of a vowel generation unit and a consonant generation unit which operate based on formant sound synthesis, so that a song is automatically swung based on lyric data and performance data. If a syllable within words of a lyric designated by the lyric data consists of a consonant and a vowel, the consonant generation unit generates the consonant with respect to a consonant sounding time which is set in advance whilst the vowel generation unit generates the vowel to follow the consonant. If generation of multiple syllables is allocated to a desired single note within notes corresponding to a melody designated by the performance data, the multiple syllables are sequentially generated during a sounding time of the desired single note. A human operator is capable of inputting words of a lyric to form the lyric data by using a computer keyboard. Or, the human operator is capable of editing the contents of the lyric data by using the computer keyboard. Incidentally, programs and/or the lyric data and performance data can be stored in an internal memory of the electronic musical apparatus; or they can be transferred to the electronic musical apparatus from an external storage device or an external system.
