While most of these seem unaccompanied, there is one (Andantino D Major C time, p.29 of the manuscript) that has indications for "canto", "flute", "ritournelle" so presumably there is an accompaniment for this that is orchestral or chamber in nature. Several have no text under the notes, but the words are given in verses on separate pages
Some of the works, textless ones, have labels such as "La Poule (contredanse)", "marche", "Valse Tyrolienne" etc. and it is unlikely that these would be sung. These have been tagged for open instrumentation
