The Circle Of Fifths poster will teach you all 12 keys, which is the root of all music and most basic knowledge that any student of music must grasp. Using this "Circle of Fifths", also known as the "Cycle of Fifths", makes the learning of key signatures enjoyable and easy. This memory process, once the Circle is understood, will take the fear out of learning the keys of Db major or even C# minor. Avoiding fear is a good thing and once your students aren't shook by accidentals, the easier the teaching and learning process will be for everyone. This graphically stimulating poster by Phil Black shows all the major & minor keys by using the Circle Of Fifths. Simply hang this poster in your music studio, practice room or bedroom wall. Any visible spot where an "at-a-glance" reminder is all you need. 11" x 17" poster.
