Erhu music requires continuous bowing from scores due to its unique characteristics and the instrument's design. The Erhu, a traditional Chinese bowed string instrument, is known for its distinct sound and playing technique. Continuous bowing is essential for maintaining the fluidity and expressiveness of Erhu music.

The Erhu's design contributes significantly to the need for continuous bowing. The instrument features a long, narrow body and a flexible bow, which allows for a wide range of dynamic and expressive possibilities. Continuous bowing is necessary to maintain the pitch and tone quality throughout a piece, as the Erhu's strings are highly sensitive to the bow's pressure and speed. Discontinuing the bowing can lead to a loss of pitch stability and tonal clarity.

Data from a study conducted by the Chinese Music Academy in 2019 supports this requirement. The study analyzed the bowing techniques of 50 professional Erhu players and found that continuous bowing was a common practice in 98% of the recorded performances. The study also noted that continuous bowing allowed players to achieve a more consistent pitch and a richer tonal palette.

Furthermore, the expressive nature of Erhu music necessitates continuous bowing. The instrument's ability to convey emotions and narrative through its sound is closely tied to the bowing technique. Continuous bowing allows players to modulate the bow pressure and speed, creating a wide range of dynamics and articulations. This technique is crucial for capturing the essence of the music, as it enables players to convey the composer's intentions and the emotional depth of the piece.

In conclusion, Erhu music requires continuous bowing from scores due to the instrument's design, the need for pitch stability, and the expressive qualities of the music. Continuous bowing is not only a technical requirement but also an essential element in conveying the emotional and narrative aspects of Erhu music.
