Kathleen Schlesinger, 1911 Encyclopædia Britannica (1911)
“ The right hand plays the melody on the keyboard, while the left works the bellows and manipulates the two or three bass harmony keys, which sound the simple chords of the tonic and dominant. The archetype of the accordion is the cheng (q.v.) , or Chinese organ, between which and the harmonium it forms a connecting link structurally, although not invented for some thirty years after the harmonium. The timbre of the accordion is coarse and devoid of beauty, but in the hands of a skilful performer the best instruments are not entirely without artistic merit. ”
