Tenor provides chord lookup for Tenor Banjo and Tenor Guitar in CGDA and GDAE tuning. There are 17 chord types in the library, each of which are supported with 3 or 4 different fingerings each, depending upon the chord. To plot a chord diagram, select the root of the chord from the Root menu, and the type of the chord from the Type menu. Then, diagram it with the Form 0,1,2,3 buttons from the tool bar. Form 0 chords are available for Major, Minor, and Dominant 7th chord forms and are generally the open or common forms of the chord. Form 1 chords generally have the root on the 4th string. Form 2 chords generally have the root on the 3th string, and Form 3 chords generally have the root on the 2nd string.

The Neck Window view provides additional chord lookup functions. This window allows the browsing of chord fingerings over the neck and has a Name-that-Chord function which recognizes 40 different chords in standard and non-standard tunings. These user-created chord voicings may then be diagramed in the chord editor window.
