Music Theory Square is a simple way to learn music theory from the circle of fifths. Learn scales, modes, key signatures, relative minor, and transposition all from one card. The front shows the circle of fifths with major and corresponding relative minor key signatures. It also shows the order of sharps and flats. The back shows how a major scale is formed by whole steps and half steps. The back also shows how to derive chords and other scales and modes from the major scale. This is a great tool for band directors, private lesson instructors, songwriters, and for learning jazz improvisation. Music Theory Square is printed on an 8" x 8" 24pt heavy card stock.
