• Appoggiatura
  • Arch-top: A guitar featuring two f-holes (as opposed to the usual single soundhole on flat-top guitars) and a pronounced curved soundboard similar to cellos and violins. The Gibson L-5 produced in 1924 is one of the first examples of a modern arch-top guitar.
  • Arpeggio: In music, an arpeggio is a broken chord where the notes are played or sung in succession rather than simultaneously. The word, like many other musical terms, originates from Italian, in which it means "in the manner of the harp."
