A method for generating accompaniment to a musical presentation, the method comprising steps of providing a note-based code representing musical information corresponding to the musical presentation, generating a code sequence corresponding to new melody lines by using said note-based code as an input for a composing method, and providing accompaniment on the basis of the code sequence corresponding to new melody lines. Providing the note-based code representing the musical information comprises steps of receiving the musical information in the form of an audio signal, and applying an audio-to-notes conversion to the audio signal for generating the note-based code representing the musical information, the audio-to-notes conversion comprising the steps of estimating fundamental frequencies of the audio signal for obtaining a sequence of fundamental frequencies, and detecting note events on the basis of the sequence of fundamental frequencies for obtaining the note-based code.
