With schools starting a new year (this was recorded in September), the timing for this musical experiment was ideal. The reason I started creating them though was because I’ve been listening to Amaranth by Nightwish a lot. It’s one of my favourite songs at the moment, with a incredible chorus that both rocks and hits all the right harmonies. When the chorus starts, I started playing with the lyrics. Rather than ‘Caress the one’, I thought, ‘Carry the one’ would be a brilliant start to a mathematical parody of the song, or in other words, an excellent mathematics ear-worm. In the final version, it became ‘Carry the number’, to apply to other sums, but the education train had begun!
