Of all of the instruments on which one can begin, I think harp is actually in the category of the harder ones.
Yes it is possible to make beautiful sounds quickly, but if one aspires to play a certain style of music, and play well, that result can be elusive.
Over my five years of lessons I have often become frustrated but in the last 6 months or so, I’ve been feeling much more positive about my goals. Some musicians can’t deal with that kind of frustration.
Also, when some young people come to the harp they’ve played piano for a period of time and are shocked to learn that they need to go back to the beginning to develop good technique for the harp, then wish to quit and go back to piano.
Beginning harpists need ongoing encouragement. If they receive it, at least for me, it’s hard to rip the harp out of my gnarled little fingers.
