acidentais

Acidentais is a term that can refer to several concepts, most commonly in the context of music and grammar. In music theory, an accidental is a symbol that alters the pitch of a note. The most common accidentals are the sharp (#), which raises a note by a semitone, the flat (b), which lowers a note by a semitone, and the natural (♮), which cancels a previous accidental or restores a note to its natural pitch. These symbols are typically placed immediately before the note they affect and are applied to all occurrences of that note within the same measure, unless cancelled by another accidental.

In grammar, the term "accidental" can describe something that is unintentional or happens by chance. For example, an accidental discovery is one that was not sought after but found unexpectedly. Similarly, an accidental utterance might be a slip of the tongue. The use of the word emphasizes a lack of deliberate intent or planning. Depending on the context, "acidentais" in this sense can imply randomness or a fortunate occurrence.
