Quickly increase the total tension of the strings to allow the instrument's structure to adapt initially, laying the foundation for subsequent fine-tuning.
Raising the pitch offsets the pitch drop caused by physical shrinkage, ensuring tension balance after the entire instrument is tuned.
Play quickly and powerfully, and on the basis of stable tension, fine-tune the harmony and stability of the unison interval.
迅速增加琴弦的總張力，使樂器結構初步適應，為後續的微調奠定基礎。
提高音高可以抵消因物理收縮造成的音高下降，確保整件樂器調音後張力平衡。
快速有力地演奏，並在穩定的張力基礎上，微調同音音程的和諧性和穩定性。
