上海手风琴厂不久前试制成功特殊规格的54贝司手风琴样琴,很快将投入批量生产。该琴借鉴48贝司手风琴原型,进行合理改进,贝司部分增加了属七和弦、减七和弦两排键钮,从而使琴的部分功能与96贝司琴相类似。
Shanghai Accordion Factory recently trial-produced 54 bass accordion-like instruments of special specifications and will soon be put into mass production. The piano draws on a prototype of a 48 bass accordion and makes reasonable improvements. The bass section adds seven-chord and seven-chord two-row keys to make part of the piano similar to the 96 bass.
