Composed in 1791 in Vienna. Since the glass harmonica (an automated form of rubbing crystal goblets) is rare these days, this charming work is usually assigned to the organ. Registration: Section 1 - Copula Major + copula minor, which is replaced with Quintadena for the repeat. Section 2 - Salicinale + copula minor, replaced by Principale for repeat. Organ Gabler temperament. [3:25]
