An appoggiatura (/əˌpɒdʒəˈtjʊərə/ ə-POJ-ə-TYER-ə, Italian: [appoddʒaˈtuːra]; German: Vorschlag or Vorhalt; French: port de voix) is a musical ornament that consists of an added non-chord note in a melody that is resolved to the regular note of the chord. By putting the non-chord tone on a strong beat, (typically the first or third beats of the measure, in 4/4 time) this accents the appoggiatura note, which also delays the appearance of the principal, expected chord note. The added non-chord note, or auxiliary note, is typically one degree higher or lower than the principal note, and may be chromatically altered. An appoggiatura may be added to a melody in a vocal song or in an instrumental work.
