- The Hulusi is played differently from a Western flute: the bass notes require vigorous blowing while the higher tones are shaped by careful air flow control, enabling expressive dynamics. - Design and portability: simple, elegant appearance with a compact structure that is easy to learn, easy to use, and convenient to carry. - C button configuration: hole spacing is moderate, producing a melodic, crisp tone that is easy to identify and is well suited for beginners. - B Key configuration: hole spacing is farther from the lower holes, comfortable for adult hands, with a soft sound and good resonance. - Build and material: traditional pumpkin (gourd) flute design, focused on reliable performance and a pleasant tonal character. - Practical use scenarios: - Beginner practice or lessons at home, building technique and tone gradually. - Travel, commuting, or outdoor playing thanks to compact size and portability. - Small ensemble or solo play, using C for brighter melodies and B Key for more mellow passages.
