Castalia Communications' posters have been putting answers up on the walls for generations of musicians. This incredible 24" x 36" poster makes teaching music theory as easy as do--re--mi. In addition to fundamentals such as the circle of fifths and the great staff, the poster shows in easy-to-understand graphics how music works. The table of keys uses numbers based on the major scale to represent the notes of scales and chords, making transposition quick and easy even for students who do not yet read music. The chord and scale table lists the formulas for all the common chords and scales, showing which scales to play over which chords in all styles of popular music. This poster also shows how to write chord charts and transpose chord progressions with the Nashville system used by professional studio musicians. This new poster is a must for every school music room and teaching studio.
