6Da Capo Aria A Da Capo Aria is basically written in ternary form. The ‘A’ section is where the singer presents the main themes of the aria.The ‘B’ section will present some new ideas, and may be in a different key.The ‘A’ section is then repeated, but the solo singer will be expected to vary it and make it more interesting by adding some ornamentation.Listen to part of the alto aria He was despised and rejected from Handel’s ‘Messiah’ as an example of this.
