Since bells/maramba/and the piano are so similar in key structure, that's one thing that really helped me learn. Wind instruments are completely different. All depends on how your lips are placed on the reed and needs quick changing at times. I guess that's why I couldn't get into those.
I'm pretty surprised, but I just found some big, possibly very revealing, PSMD news. This requires a spoiler tag tho as it contains spoilers from Pokemon Mystery Dungeon Explorers of Time/Darkness/ and Sky.
