Livre d'orgue d'Entrevaux part 1

The manuscript belonged to Felix Delmotte (1754-1800), organist around 1774.
The organ pieces are typical french liturgical pieces. Some works are for the harpsichord. One of the longest pieces can be attributed to Charles Piroye.
I propose here the first 16 pieces. There are a minor and G major pieces together.after the titel "Te Deum". Different tonalities are surprising in the same work, as such is a piece describing birds....
