The global message of this piece is movingly conveyed with pop-like harmonies and simple and accessible vocal lines. The large range of dynamics should be carefully observed, and the crescendos and diminuendos carefully paced. The word ‘know’ is repeated several times: be careful not to move to the ‘ooh’ part of the diphthong until the end of the note. Make sure the middle section is taken quickly enough, and explore a different vocal colour: a darker and richer sonority is needed here.
