I am trying to identify a hymn tune. The only information I have is as follows:
Composer: Johann Anastasius Freylinghausen (1670 - 1739)
Incipit of tune: 354321232544323

I need to find the following:

1. Name of tune
2. Date of composition
3. First published source (title, author / editor, place and date of publication)

For information, an incipit is a method of notating the first fifteen
notes of any given piece of music. In the key of F, 1 = F, 2 = G, 3 =
A, 4 = Bb, 5 = C, 6 = D, 7 = E.

I have looked up the incipit in the Hymn Tune Index on the Internet,
but have drawn a blank. As hymn tunes are identfied either by name or
incipit, I am unable to go any further!

Is it possible that the incipit is one number off?
Could this link be part of what you are looking for?
