Lol, all the poll results are tied right now. :xd:
I loved the harp, although it was like the rest of the game in that it was a great execution with some weird flaws that shouldn't have been there. My issues with instruments in past Zelda games are with, well, how they were used. In Ocarina of Time, for example, there was essentially no reason for the Ocarina to exist as an item. You played it to advance special plot sequences, and then primarily for warping and a handful of other odd powers, but this meant you had to stop playing, pull out the item, and input a memorized sequence of buttons (assuming you memorized it; if you didn't then the process became a total pain in the ***). There's no reason that you should have to input a string of buttons to use all of these abilities past maybe the first time you learn or perform it, because it's not really fun. It's not that entertaining for me to actually play the songs in OoT, MM, or TWW, because there's no actual challenge. It's not gameplay. There's no skill involved.
That's why I was a fan of the Spirit Flute in Spirit Tracks, and to a lesser degree the Wolf howling in Twilight Princess, because those both required a degree of skill to perform a song. It was a section of legitimate gameplay, like music games where you have to input buttons with correct timing to play a song. You can fail. It's gameplay.
What I like about the harp is that it is used in story sequences as just that, a section of gameplay that might take a little practice and is actually kind fun to do, and you're not forced to replay the songs all the time to do basic things that should be handled with the press of a button. Additionally, the songs sound gorgeous, and I love how you can mess around with the harp whenever. I know other instruments in other games let you do this, but it feels better here, probably because I have direct control over it.
What I didn't like about the harp, and this is what I was talking about when I mentioned weird design flaws, is that you don't use it that much. You can strum it to activate Gossip Stones and Goddess Walls, but other than that it's used less than sparingly. Now I don't want it to be used for everything, but that doesn't mean they shouldn't implement plenty of moments that use it, just not tie the whole thing into basic actions, because that's annoying. I also don't like that you can't actually replay the songs you learn whenever you want. I love being able to freestyle, but I'd like to be able to perform the stuff I learn too... -.-
