Class DiatonicIntervalPatternTransformer

java.lang.Object
  org.jfugue.PatternTransformer
      org.jfugue.extras.DiatonicIntervalPatternTransformer

All Implemented Interfaces:

java.util.EventListener, ParserListener

public class DiatonicIntervalPatternTransformer
extends PatternTransformer

The DiatonicIntervalPatternTransformer transposes all notes in the given Pattern by a diatonic interval (1 -- unison, 2 -- second, ... 8 -- octave, etc.). It only handles upward motion and assumes the key of C. However, it could be used in conjunction with IntervalPatternTransformer to change to another key and/or perform downward motion.

For general information on how Pattern Transformers work, refer to the JFugue documentation.
