# Composer.App

A simple console application written in *JavaScript* that generates a chord progression in a given musical key.

The progression could be used for improvisation and educational purposes.

===================================================

Composer.App supports the following functionalities:

- *_random-key-selector.js_* => chooses a random key to be constructed

- *_key-generator.js_* => creates the main scale of the given key

- *_chromatizer.js_* => appends the required chromatic signs for the chosen key signature

- *_chord-generator.js_* => generates all of the main chords in the tonality with their applied dominants

- *_progression-generator.js_* => creates a simple chord progression in the chosen key applying the traditional laws of tonal harmony

- *_colorizer.js_* => inserts applied dominants, ii-v 'movements' and appends final cadence

- *_tonal-mapper.js_* => maps the progression to specific chords in the particular key

- *_chord-mapper.js_* => maps the chord abbreviations to full representation of the chords

- *_dominant-mapper.js_* => reads dominant seventh chords and modifies them where necessary

- *_note-alterator.js_* => adds accidentals for raising or lowering chord tones

- *_randomizer.js_* => helper function for random selection of integers used throughout the application

- *_app.js_* => main entry point of the application

===================================================
