About MusicPlant

    The Musical Plant is a virtual life that resides in a PC and accepts signals from a MIDI control devices such as a keyboard. The plant grows as it receives MIDI signals, and it takes a shape that is determined by the characteristics of the input. The shape thus becomes a reflection of the MIDI input. Some MIDI songs will generate complex shapes while others will generate relatively simple shapes according to the musical form of the MIDI song.
    Before the musician begins to input a MIDI signal, the primitive plant is rotating at the center of the PC display. As signals are input, branches are added to the plant. Each MIDI note generates a branch of the plant. The angle of each branch is determined by the musical context of the note. Plant characteristics such as branch colors, rotation speed and rotation angle are changed with respect to MIDI parameters such as velocity and note intervals.
    When input of the MIDI signal stops, the plant begins to decompose. In this process, each decomposing branch creates a series of sounds. The sound intervals are derived from the notes that made the branch. The decomposing process has two configurations. One configuration is horizontal reversing and another is vertical reversing.
    Horizontal reversing, in this sense, means that the order of decomposition - proceeds from the first (innermost) branch to the last (outermost) branch. Further, the sound of a disappearing branch has the same interval as the note that formed the branch.  Therefore, the collection of these sounds essentially reverses the original sounds.
    Vertical reversing means that decomposition proceeds in the same order as in creation, but the sound of each disappearing branch reverses the interval of the original note. That is, when the interval is reversed, higher notes become lower notes. Also, when reversing is applied, minor chords become major chords since the relation of notes is reversed.
    The musical plant analogy provides a way to visualize the composition and decomposition processes. For example similar MIDI songs will tend to generate similar plant shapes. The music plant analogy also aids in determining the essential elements of a "good tune". Many well-known songs also sound good when played in reverse order.

(2) Illustrates the fact that reverse music still holds some texture of original tune.
