This view allows you to define how your Harmony Rules behave.

Name

The name of the Harmony Rule.

Value

Alter the height of each of the bars in the display, by clicking the mouse at the appropriate position.

The relative height of each bar, indicates the relative probability of a note being chosen for a Voice, where the note being considered is the indicated semitone distance from a note already selected as being composed at the considered time for any Voice other than the one being composed for.

By way of example, imagine that you have three Voices, called X, Y and Z.

Imagine that at some time in the piece, Noatikl has already chosen to play note C for Voice X, and note G for Voice Y. At that time, Noatikl thinks about composing a note for Voice Z. It looks at the notes available for it to compose, and adjusts the probabilities of choosing each of those notes, by applying the Harmony Rule bar heights for each of those two composed notes which are active at time (i.e. notes C and G).

Harmonies are always calculated based on a rising direction up from the Piece Root. So, if Noatikl is using a Piece Root of B, and Noatikl is considering if it can compose note D for Voice Z, and it looks at the note it needs to harmonize with which is note C for Voice X; then Noatikl figures-out the Harmony Rule values for Voice Z from the C of Voice X, up and through the Octave (i.e. E, F, F#, G, G# etc.).

Confused? Well, it should all become clear when you start playing with it!

A bar with zero height, is one that will not be chosen by the Noatikl music engine.

The text on the the left of the bar (e.g. m2) defines the relative position in the harmony rule governed by that harmony rule bar. The blue text on the right of the bar is a value from 0 to 100, proportionate to the bar height, which is especially useful for keeping tracks of bars that have small values which might no otherwise be visible.
