Abstract
A music chord indicating calculator assists in determining finger placement to play musical chords on a multi-stringed musical instrument containing a finger board. The device has an outer slide member and an inner base member which slides through the outer slide member. The slide member contains a number of columns of spaced viewing ports on both side faces. The inner base member has a number of columns of spaced indicia which are coded to correspond to various chords. A chord selector has one of the indicia on a column of indicia on the base member and can be viewed through a viewing port which has a chord identifying name associated with it. By sliding the base member and slide member relative to each other such that chord selector is viewed through a viewing port which identifies a chord by name, the finger placement of that chord can be viewed through the viewing ports by coding of the indicia on the base member.
