Circle of Fourths

This handout featuring the circle of 4ths makes it quick and easy for transposing instruments to find concert pitch. For example, those who play B-flat instruments can hear you say, "Play a concert D" and move two "notches" or two notes counterclockwise to find the note they play to sound like a concert D (which would be an "E"). This handout explains the process, and also provides all the other benefits of the circle of fourths or fifths, such as showing how many accidentals are in each key and the order of flats and sharps
