It wasn't really a bad instrument, it just wasn't used in a way that we were all accustomed to. I wasn't really a fan of how it was used, I wish it was more interactive, if that makes sense. It was basically keeping in time with a beat, no notes or making your own songs. It didn't really serve any purpose either besides finding Goddess walls, or to activate something in the main quest. It was similar to the pan flute in Spirit Tracks, but even then it was a bit more fun to play. In Ocarina of Time, the Ocarina had a multitude of uses, besides the main quest. You used it to call your horse, repair a sign if you wanted and warp to various places. Granted, Ocarina of Time had Ocarina in the title, it was meant to play a bigger roll. The harp had a place in the story, but it wasn't as much of a big deal. I would like it better though if it was playing notes instead of just strumming. It's basically just the notes going up and down in a scale, and I don't really remember the songs that well either. It's also really simple, just back and for with the Wii mote. The harp itself I like as an instrument, I just wish it was used a little different.
