text: The spinet organ's pedalboard normally spans only a single octave, is often incapable of playing more than one note at a time, and is effectively playable only with the left foot (and on some models only with the left toes). These limitations, combined with the shortened manuals, make the spinet organ all but useless for performing or practicing classical organ music; but at the same time, it allows the novice home organist to explore the challenge and flexibility of simultaneously playing three keyboards (two hands and one foot).  User guides suggest playing the root note of the chord on the pedal. The expression pedal is located to the right and either partly or fully recessed within the kickboard, thus conveniently reachable only with the right foot. This arrangement spawned a style of casual organist who would naturally rest the right foot on the expression pedal the entire time, unlike classically trained organists or performers on the earlier Hammonds. This position, in turn, instinctively encouraged pumping of the expression pedal while playing, especially if already accustomed to using a piano's sustain pedal to shape the music. Expressive pumping added a strong dynamic element to home organ music that much classical literature and hymnody lacked, and would help influence a new generation of popular keyboard artists.
