Chord King was designed to allow you to play both chords and scales on the same screen. The idea of seeing and hearing them together leads to a primary discovery of the basic function of music. Chord King is a repository for the basic elements, chords, scales and modes. It gives you easy and intuitive access to over 10,000 chords and over 1,000 scales. You can view and hear all chords and scales on the guitar fretboard, the piano, the clef, and the tablature box. And have a full explanation to the origin of each chord and scale at all times in the information areas. The upper portion of the program window switches views. From the chord database to the tablature box, to the scale selection box, to the Musical Alphabet. There is an optional 88 key piano view at the bottom of the program window which reacts to every facet of the program. The main program window shows two guitar fretboards. One for scales and one for chords. Chord King is built around an octave view. The notes that appear on the fretboards and piano are determined by the notes on the clef. This enforces the idea of reading from the clef. The tablature box for chords gives an arpeggio and for scales gives a basic interpretation of the scale. Chords are found by the main menu. And can be displayed by chord type or by Key. Scales are found in four places. The mode buttons, the scale box on the upper portion of the program window and two dedicated scale utilities. Everything you enter into the program can be played ascending and descending across the full range of octaves of an 88 key piano. You have control of all chord and scale instrument sound, volume and tempo settings.
