The sisters copied and decorated sheets of music.  Beissel was famous in the colonies for his original music.  Upon learning the basic rudiments, he immediately appointed himself choir director.  The hymns that the choir sang under his direction were so outstanding that their enchanting tones became known far.  During his lifetime, he wrote 1,000 hymns, 44 of which were published. 

A description of Beissel’s music, which was published in the 1853 Hazards Register of Pennsylvania by Mr. Fahnestock reads:

“The tones from the choir imitate soft instrumental music conveying a softness and devotion almost superhuman to the auditor.  The whole is sung in the falsetto voice, the singers scarcely opening their mouths, or moving their lips, which throws the voice up to the ceiling, which is set high, and the tones, which seem to be more than human, at least so far from common church singing, appear to be entering from above, and hovering over the heads of the assembly.”
