可變後弦長Viola拉弦板(4孔微調)

可變後弦長Viola拉弦板(本產品附4孔德國勾式兩用微調)

在弦樂器（如小提琴、中提琴、大提琴、低音提琴）中，拉弦板（Tailpiece，又稱尾部固定板）扮演著至關重要的角色。它不僅僅是一個用來固定琴弦的配件，更是影響樂器整體音色與結構平衡的核心部件。拉弦板的位置和長度，直接決定了後弦長（After-length）即琴橋（Bridge）到拉弦板之間那段不被演奏、但會產生共振的琴弦長度。後弦長度如果太長或太短，會改變這段短弦的泛音共振頻率。本產品拉弦板結合可變換模組段及主體段，調整後弦長泛音設定，後弦的共振可極大地增加樂器的音量、改善音色的豐富度，並提高樂器的靈敏度與發聲均衡；完全改變傳統拉弦板無法全部設定後弦理想長度，導致聲音悶啞、尖銳或出現嚴重的「狼音」問題。

In string instruments (such as the violin, viola, cello, and double bass), the tailpiece is a critical component located at the lower end of the instrument's body. It serves three primary functions that directly impact the instrument's structural integrity, playability, and tone quality: (1) Anchoring the Strings & Managing Tension; (2) Controlling the "After-length" to Optimize Tone; (3) Housing Fine Tuners for Precise Tuning.

The position and length of the tailpiece dictate the after-length—the segment of the string between the bridge and the tailpiece. Afterlength is not supposed to be playable, but affect resonance respond. The afterlength is too long or short will interact frequency with other string sound. This product(AATB) integrates main tailpiece body and changeable tuning module for afterlength definition by beads location. Corresponding setting engages string sound volume and overtone. It promotes sound enrichment, respond, and balance without dimmer backside that traditional constant afterlength tailpiece. It is the best way to get rid of 'wolf tone' in nature.
