4Characteristically rags have a steady boom-chick boom-chick in the left hand with the bass notes sounding on the beat and chords sounding on the and of each beat Does the left hand play this?

Yes, in ragtime music, the left hand typically plays a steady alternating bass pattern known as a "oom-pah" or "boom-chick" pattern. The bass notes are played on the beat, while the chords are played on the offbeat (the "and" of each beat). This rhythmic pattern creates a syncopated feel that is characteristic of ragtime music.
