I recommend Hulusi. I do online marketing and music marketing and found that 80% of adults choose Hulusi as their first choice. First of all, Hulusi sounds more beautiful and gives people a harmonious feeling. It is for this reason. , even if you don’t know how to play it, you won’t find it unpleasant. Then, the range of cucurbit flute is relatively low, and there are not many requirements on the use of breath. It is easy to learn. Moreover, the cucurbit flute music score uses simple notation, which can be understood without any knowledge of music theory. The guitar uses six-line music notation, which is much more complicated. . Finally, there are many classic songs in Hulusi that are easy to play, such as "Wedding Vow" and "Phoenix Bamboo in the Moonlight", which are suitable for quick learning. The guitar erhu may have higher requirements on the fingers and may require higher basic skills, so it is not so easy to learn. In fact, the most important thing is to see what you like. After all, interest is the best teacher. I personally prefer Hulusi, so I recommend Hulusi, haha. Hope this helps.
