Joseph Funk, his work and his
Harmonia Sacra are well-known in many shape-note circles. The
Harmonia Sacra is still used at singings in the East among the Mennonites and others. (It has some very nice songs in it.) His grandson Aldine S. Kieffer is also one very important person in shape note history.
Funk was a developer and leader in shape note printing, but the initial invention is usually credited to John Connelly of Philadelphia, Pennsylvania around 1790. William Little and William Smith credited him in their song book
The Easy Instructor, which first came out in 1801. Andrew Law asserted that he was the inventor of shape notes, using them in his
The Musical Primer in 1803. Of course, that is two years later than Little and Smith, and five years later than Connelly's note below.
Law's shapes were only slightly different, but he dispensed with the use of a staff -- possibly dooming his idea to failure.
