Think of pulling daisy petals and start counting on a music scale. As it is customary, you start with ‘he/she loves me’, so for the music, the first note will be included in our progression. That leaves us only with the 1-3-5-7-9-11-… degrees of a scale. (I know that there are only 7 unique notes in each scale, so when you run out of notes, start again from the beginning!) Most basic chords are 1-3-5 chords. If you want to spice things up a little bit, you can have 1-3-5-7, 1-5-7-9, 1-3-5-9, 1-7-9-11 and so on.
