David Wolfert, who has written hit songs for Whitney Houston, Barbra Streisand and Cher, and who composed the score for my film True Bromance says: “Our enjoyment of music is based on a combination of the tune going where we are culturally conditioned to expect it to go, and how it surprises us from time to time by not doing what we expect. Children like the more expected musical path. This tune, which starts on the first degree of the scale, or tonic – C in the key of C – then comes to rest on the fifth step of the scale on the word ‘star’. The fifth step – G in the key of C – is known to be the second strongest step to our Western ears. The tune then returns to the tonic again on the word ‘are’, which satisfies our expectation of completion.”
