In this lecture, sara talked about the power of the chord G# and how it is used in songs in order to make the sing sound similar to others. A lot of artists use the chord in this way. However they can change it ever so slightly in order to trick the listeners into thinking that it is something new. Some of the examples that we were shown in the lecture are as follows.
Dire Straits - Brother in Arms
Lady Gaga - Poker Face
Both of these songs use the chord G# Minor however sound completely different. It is clever how artists do this and does in fact show how powerful the chord is. I am interested in music myself, and actually contemplated taking music forward to college, however i now just play drums and dabble in compositions as a hobby.
