SuggestionBeginners should choose a tuning. There are various different tunings for the hulu and the flute. Generally, the most commonly used tunings for the hulu are: "B♭, C, D, G, F, A". How should one choose? Generally, beginners should choose a medium-pitched hulu, such as a B♭ tuning or C tuning hulu, which is more suitable. Because these tunings have moderate pitch and are easier to play, they are often used in performances. If possible, one can choose two hulu, one in B♭ tuning and C tuning. As long as you have these two tunings, almost half of the hulu pieces can be played.

Adults: Generally recommended to buy the B-flat tuning, as the distance between the holes is suitable, and those with larger hands can also easily press it.

Children: Generally, it is recommended to buy a C-tuned HuLuSu because the distance between the holes on a C-tuned HuLuSu is smaller, making it easier for children to play.smaller
