I have two pedal harps that I  perform on. These harps are made by the same company and look exactly alike  except that one is larger. I bring the harp that I think is most suitable to the location and event. The larger of these harps has 47 strings and is 75 inches tall.  The smaller has 44 strings  and is 67 inches tall.  

I often do weddings on the 44-string pedal harp. 

Of the two pedal harps, the 44-string one is the one that I take outside most of the time. 

These harps are heavy and I need to know ahead of time about any steps so that I can decide if I can make the situtation work with one of these larger harps or if I should bring my lever harp instead.

My 36-string lever harp is a full 5 octaves and is made from exotic bubinga wood that gives the harp a lovely warm tone that carries well. I sometimes use this harp for  weddings and private parties.  The harp is fairly easy to move and stairs are of minimal concern when I play this harp as it weighs only about 30 lbs. While I cannot play in direct sunlight with any of the harps, I sometimes choose this harp when asked to play outside.  This is also the harp I use when performing in my harp duo Enchantment. The harp is 54 inches high.
