Composer-Engine-in-Java\n\nA console application written in *Java* that generates a chord progression in a given musical key.\nThe progression could be used for improvisation and educational purposes.\n\n========================================================================\n\nComposer.App supports the following functionalities:\n- *_RandomKeySelector_* =\u003e chooses a random key to be constructed\n- *_KeyGenerator_* =\u003e creates the main scale of the given key\n- *_Chromatizer_* =\u003e appends the required chromatic signs for the chosen key signature\n- *_ChordGenerator_* =\u003e generates all of the main chords in the tonality with their applied dominants\n- *_ProgressionGenerator_* =\u003e creates a simple chord progression in the chosen key applying the traditional laws of tonal harmony\n- *_Colorizer_* =\u003e inserts applied dominants, ii-v 'movements' and appends final cadence\n- *_TonalMapper_* =\u003e maps the progression to specific chords in the particular key\n- *_ChordMapper_* =\u003e maps the chord abbreviations to full representation of the chords\n- *_DominantMapper_* =\u003e reads dominant seventh chords and modifies them where necessary\n- *_NoteAlterator_* =\u003e adds accidentals for raising or lowering chord tones\n- *_Randomizer_* =\u003e helper function for random selection of integers used throughout the application\n- *_MidiCreator_* =\u003e creates MIDI file with the generated progression\n- *_Generator_* =\u003e main entry point of the application\n\n\n========================================================================\n\nExample progression generated by the application:\n\u003cbr\u003e\u003cimg src=\"https://github.com/Mithras11/Composer-Engine-in-Java/blob/main/example-progression.png\"/\u003e\n\nwhich could be realized on the piano in the following manner:\u003cbr\u003e\n\u003cimg
