Pedal Steel Data" is an app about pedal steel guitars in the popular E9 tuning. Several charts present information about the tuning, pedal/knee lever actions, notes, harmonies (double-stops), chords and major scales in multiple ways. All of these can all be heard by selections of strings, frets, grips, pedals and knee levers. The pedals considered are pedals A, B and C with the standard actions. The (knee) levers considered are the left knee left (F) and left knee right (D). A detailed user guide is presented by selection of the "INFO" toggle button on the home screen.
