![]() Composition parameters such as key settings and the upper and lower bounds of the melody pitches can be organized with the pull-down menu options. ![]() Users can manually correct the prosody by editing the string in the text field. ![]() Prosody of the lyrics is analyzed with the text-to-speech engine of Galatea Talk, and shown in the text fields located in the boxes. In the latest version (version 3) of our system, around 30 chord progressions, 65 rhythm patterns for melody (including 10 patterns which are able to generate melody with auf- takt), and 37 accompaniment patterns are installed for the user to give directions on generating songs. Users can choose composition parameters for each segment. Each segment of the song is represented with a box. When the user proceeds past the lyric input interface, the terface for giving directions on composing songs will ap- pear. Radio buttons for choosing the preset parameters set for composition are available at the bottom of the interface in order to avoid irritating users with having to set a lot of composition parameters. In case the user could not find out what lyrics to input, the system provides the user with an automatic lyrics generator, which can generate lyrics from input of 1 to 5 keywords and then interpolate between keywords with an N-gram model trained with lyrics database. Users are also provided with reserved symbols for instrumental segments mark- up, used for the generation of intro or endings to the song. Linefeed code is used for setting the structure. Here, users can input their lyrics in the text field. The lyric input interface appears when the user accesses the web site. This is our third version of “Orpheus” automatic composition system series. System design and the composition algorithm discussed in Sections 2 and 3 have been implemented. “Orpheus version 3” is a web-based system for automatic composition where users can create songs from Japanese lyrics with choice of composition parameters. However, obtaining the optimal pitch sequence be- comes O ( N ) by using dynamic programming. Since there are 128 possible sequences of pitch, it is computationally unfeasi- ble to search all of the possible sequences for the optimal one.
