hi - Here are some basic skills for steel guitar - using the bar to slant across stings to play harmony notes. On a pedal steel, the pedals change string pitches - but on a lap steel, the ‘old school’ technique of slanting the bar lets you play harmonized scales and melodies. This is and advanced technique that yields great benefits!
