Appoggiatura

An appoggiatura (/əˌpɒdʒəˈtjʊərə/; Italian: [appoddʒaˈtuːra]; German Vorschlag, Vorhalt; French Port de voix) is a musical ornament that consists of an added note in a melody that is resolved, delaying the appearance of the principal note. The added note (the unessential note) is typically (though not always) one degree higher or lower than the principal note; and, if lower, it may or may not be chromatically raised.
