How it Works
Transposing from the key of "C" to the key of "D".
Rotate the Present Key arrow on the middle dial
to the keynote "C" on the outer dial.
Place the Final Key ("D" in this case) on the inner
dial under arrow.
Read the corresponding note or chord roots (it
depends upon what you wish them to represent)
from the outer and inner dials opposite their
respective indices 1 through 7 and halftones
indicated by asterisks.
More Examples
A set of supplementary
instructions is available online. This includes detailed
instructions about the transposer and describes at least 10
different applications. Many more are possible.
