Abstract: A song writing method and apparatus using a touch screen in a mobile terminal are disclosed. The song writing method includes: displaying, upon activation of a song writing mode, an onscreen musical keyboard of an octave on the touch screen; identifying, when a key of the onscreen musical keyboard is touched, a musical note mapped to the touched key through computation of coordinates of the touched key; creating musical interval data on the basis of the identified note and the current octave level; and converting the musical interval data into sound data recognizable by the mobile terminal and outputting the sound data. Hence, various types of songs can be conveniently composed through the song writing method employing the onscreen musical keyboard. The applicability of the mobile terminal can be extended through a function that can mix a written song with contents generated through various musical instruments.
