Hupfeld Phonoliszt Violina Model A, c. 1910

Ludwig Hupfeld A.G., Leipzig. Coin-activated pneumatic orchestrion with piano and three violins, driven by a 230-volt electric motor, in oak case with cloth-backed fretwork panels, rounded doors and carved integral pediment flanked by brass-capped columns, 166 x 119 x 225 cm, excellent restored playing condition, with 93 old and recut music rolls. - Note: A single string (D, A and E) is played on each of the violins, while the other strings resonate. The traditional violin bow is replaced by an octagonal wheel laced with horsehair. The sensitivity and finesse of the rendition are achieved by the speed of the bow, the pressure of the violins on the bow and the artificial fingers. Thus, a number of different types of stroke, including legato, staccato and vibrato, can be represented expressively in mechanical form. To accompany this, 44 piano notes are played with nuance.
