When you ask musicians, all of them would agree that harp is far by one of the most difficult instruments to play. For you to learn how to play the instrument, you need to know the basics not just in playing the instrument but as well as music theory. In playing harp, you need to use both hands for two sets of notes. The left hand plays the accompaniment while the other creates the melody.
This may appear as easy but when you start playing, it gets more complicated especially if you do not have any experience in playing any musical instrument before. For those who know how to play piano or any string instrument, it is an advantage. When you know how to play any musical instrument, you are at least knowledgeable with notes and music theory and this is definitely a good thing. You only have to take time and be patient in learning harp.
For you to be actually really good at playing, it does not take overnight. You need to constantly practice. Is there a need to purchase a harp? It really depends. You can either buy or rent the instrument. What is important is you can spend time for practice.
