Musically, the madrigals avoided blatant archaisms, but their texts were imbued with them.
However oblique the harmony, it is plainer than is the case with the madrigals.
There are also a few examples of poetic texts not organised into triplets, and lacking the ritornello, that are set to music as madrigals.
Nuptial madrigals were printed as a set of single leaves, one for each voice-part.
At wedding parties, the usual musical gift was a madrigal or villanella.
One telltale pointer is the presentation of the same madrigals the same order in earlier sources.
I have deliberately chosen a text with forms of pseudo-communication that recur, but probably do not predominate in the madrigal repertoire.
This is actually the only instance, albeit repeated, of a full authentic close in the whole madrigal.
