FORMAT: Laminated Cards Music theory made easy! These laminated cards are the definitive charting, transposing and music theory tools for all musicians, no matter what their instrument. The Table of Keys is the best transposing tool ever made because it also shows how to write chord charts using "The Nashville System" of Roman Numerals to represent chords: I, IV, V etc. The Chord and Scale Table- not only lists all the chords and scales (including the modes) used in popular music it also shows you which scales to play over which chords in the many styles of today's music. These two tables are indispensable for students, teachers, arrangers, composers, choir directors, band leaders and songwriters. As one music teacher told us: "It's like having Juilliard on a card!"
